>>2047439 (OP)
Sauce/Explanation on OP image

>>2047443
just googled vintage cycling

>>2047443
Old photos were often staged like that, cause photographic plates weren't very sensitive, so you had to hold a pose for like half a minute to get a sharp image.
Fun fact: photos were so expensive, lots of people only got one for communion and marriage.
If a child died before communion, some families propped the corpse up in a natural pose so they had a photo for remembering them.

wait are fixed speed bikes like... they can't spin the pedals? theres no clicky thing?

>>2047454
Fixed gear means yes there's no clicky thing (freehub), the pedals, gear, and wheel move as one

>>2047448
the photographer "dodged" all their faces in a (not particularly successful) attempt to soften up the dark shadows. while printing from the plate, they'd put a little disc of cardboard on a wire and hold it over each face on the print for a while so the exposure never gets as dark as the rest of the picture. you can "burn" it, too, with a sheet of cardboard with a hole cut out to darken areas, too.

>>2047455
som.. how the fuck do you ride?.. you have to FOREVER spin the pedals no rest?
how do you go downhill? what if your foot slips? do you just die or have to get your legs broken to stop?

>>2047459
Yes. It's basically ride or die. You either ride, or you die.

>>2047460

>>2047459
believe it or not, they'll tell you it's better and more "pure" that way.
you'll notice most fixed riders are male and teens or early/mid twenties. when they age out of "I can punish my body with no consequences" they ditch all the "pure" rhetoric and quietly get into gravel biking.
young, dumb, and full of cum.

>>2047467
also, a bunch of them are (or were, when the fixed scene was big) into the hardcore punk scene, which is also lots of holier-than-thou people: straight-edge, vegan, etc.

>>2047467
um actually its about being coupled to the road.

>Single speed bikes typically can reach speeds of 15-25 mph
>7-speed bikes typically also can reach speeds of 15-25 mph
So is the ONLY real advantage of a derailleur is that they can climb hills somewhat easier? Because I can climb most gradients just fine on my single speed

>>2047472
>mph
why is this thread a hamburgerfest

>>2047472
Why are people always autistic, almost as if bicycles were a card game or TRPG.
The primary determining factor is always the rider and their intentions. There are people in this world that could mog most normies on a modern superbike using a dutch bike or a rikscha.
A fixie, given the same rider, aerodynamics etc. will be going exactly as fast as a derailleur equiped bicycle at the same ratio. Change the conditions and the guy on the fixie will either spin out or grind hard, slowing him down. The other guy will just shift which enables him to continue producing maximum sustained power.
Single digit improvements in drivetrain efficiency on the fixie are a purely academic discussion and for the shifter there will even be one cog per chainwheel where the chainline is straight and the discussion will be even more hypothetical.
All this is true until something goes wrong. Things are more likely to go wrong on the shifter.
The fixie is cheaper to run. It's potentially lighter. It's less prone to failure. It's easier to maintain. It let's you do things that are impossible on a freewheeping bike if thats your thing. It's quieter.
TL; DR: The modern deraileur bicycle almost always offers better or equal performance and comfort. This is why it is ubiqitous in sports and transportation.

>>2047472
you can also accelerate a lot faster, going through the gears. I ride a race geometry road bike and am constantly shifting gears

>fixie
Single speeds are not fixies anon

>>2047472
you can go way faster than 25 mph after you work up to high gear combinations. the highest I ever clocked was 46mph in something like 52/11 but I was mashing down a prolonged downhill

>>2047475
derailers suck.
IGH master race.

once I build my Frankenstein full suspension IGH commuter MTB with a baggage rack you'll see.

>>2047475
>Single digit improvements in drivetrain efficiency on the fixie are a purely academic discussion
It's not, there will be an appreciable difference in pedal efficiency with a derailer. The biggest source of drivetrain losses will be chain deflection, as most gears on a casette are not directly paralel to the crankset. Chain deflection adds resistance

>fixie
when you run SS you might aswell just run fixed, either way the difference has absolutely no bearing on my observations and explanations, we are considering nicycles that are being pedalled
>>2047480
wow. The next guy who seems to buy into a narrative where bicycles were somehow inteinsically limited to some speed and not merely governed by all sorts of circunstances external to them but then half way acknowledges that.
>>2047483
>IGH master race
well lucky me im on an IGH daily but the response to >>2047472 would have completely missed the question that was specifically about
>deraileurs
and also unnecessary complicated by the fact that IGHs have so far consistently tested to have an overall worse drive train efficiency than deraileurs and single speeds (including fixies) which could potentially distract people who have no clear picture of the relation of aerodynamic drag to rolling resistance and drivetrain efficiency.
Im curious, how did you sort out chain tension on a fully? Did you use a chain tensioner? Might aswell just derailleur in that case.

>>2047485
I didn't do anything yet I don't even know if it would work honestly. just meming.

also >efficiency
you can look at it as a drag, or you can look at it as free exercise

>>2047484
This is literally something I have alluded to. I have also gone on to explain that for every chainwheel there is onr or two cogs for which the chainline is perfect or close to that. But still, for some unknown reasons dimwits will never get this: At any sort of decent speed, like your 1 hr max, aerodynamic drag makes for 90% of all resistance. Rolling will make the rest. Drivetrain efficiency, being thought of as efficiency and not drag of course, is a factor that needs application to the total power of course. So at say 200 watts the difference, as indicated by
>picrel
would be a staggering 2 Watts! Wow I hope you shaved your legs.
But the point I was making still is just as valid:
Say you have a 48 - 17 fixie (or ss...) and you compare it to a derailleur equipped bike. You could put the 48 - 17 ratio exactly where your neutral chainline is. At that very ratio both bikes would be effectively the same (again: Save for the even less relevant jokey losses) and only once you shifted the deraileur bike would be less efficient but once conditions force that shift the guy on the single speed is physiologically far less efficient.

oh nvmd

I prefer single speed bikes and I think it's a crime that they're no longer the "standard" because they're usually more robust and easier to maintain overall than multispeed bikes. I fell like derailleur only became standard because they look good on a department store bike rack and nothing more. The average person does not shift agressively enough to ever even take advantage of the extra gears.

>>2047491
>not ever even taking advantage
descend at 90 without spinning out
climb 15% all day without being a fatass and nuking your knees
yeah sure weird how that ever caught on

>>2047492
You took the consoooomerpill, single speeds can climb 15% gradients just fine, hell I'm out of shape as fuck and I almost prefer climbing with a fixed single speed cadence up hills

>ride bike around town

>no kickstand

yeah i can lean it against a wall i guess, kickstands look so awful... surely there is a solution?

what the fuck do you people do? do i just get a kickstand?

>>2047459
>want to go

>want to slow down

its not that complicated anon its just a super simple bike. try it before you knock it

>>2047498
I must believe you are misunderstanding my comment on purpose
>you took the consoomer pill
yes. I like bicycles, which is why I own several bicycles, amongst them two fixed gears and a single speed. Yes they do climb just fine. If I really want to I'll even climb on my usual 48-17.
It is not like you do not consume anything and it is not like its inherently a bad thing consuming things.
But here is the thing (you) do not or pretend to not understand:
There are physical pimitations to what one ratio can do. When descending you will spin out. It is physically impossible for you to spin past 250ish or whatever cadence. You might hurt yourself trying.
The same applies to climbing: It is a simple question of physics and yes, while it is generally possible to apply more force to the cranks than what is equivalent to your bodyweight you generally don't and you especially won't do for long (you'd be sustaining kWs at this point any might just aswell win any prestigious race in the world if you choose so). Again: You might hurt yourself trying.
You'll especially hurt yourself trying to descend on a ratio that lets you climb 15%+ climbs or trying to climb on a ratio that develops 8m+.
In any case you're phyisologically unable to produce certain power at very awkward cadences. Guess what: Deraileurs solve this issue.
Idk but you havent ever ridden a bicycle if you do not understand this.

>>2047498
Maybe but you will spin out on the flats

>spoke length calculator says 160/163mm
>LBS says 175mm
Should I go with what my LBS? They've never been wrong so far.

>>2047512
repeat all your measurements. don't rely on those from the manufacturer.

>>2047512
1 (one) mm is the most you can get spoke lengths wrong.
More than 10mm is not even the ballpark.
If its a rear wheel i'd generally expect two spoke lengths. That would quickly tell you PBS is wrong.
Measure everything, do not rely on manufacturer data, tables, online databases there is even hubs that changed hole circle diameter.
You need to measure repeatably to well below 1 mm. If you get the ERD wrong by just a half mm thats your entire margin gone basically.

Just get a kickstand, it's that simple. if you have the space for it, get a central kickstand.

>>2047509
Get a Clickstand™.
They are light as a feather and collapse down so you can store them in any frame bag or backpack. They even come with handy brake lever clips so you can safely leave it on a hillside. Brilliant invention, especially if you ride with a load. Invaluable for touring.

>>2047533
or just find a stick?

>>2047508
You can prop your bike up on any convenient rock or curb as long as there's no wind to blow it over.

>>2047508
if you want.
people that don't like them just view them as extra weight that they don't need since it's easy to ride up to something to lean on (98% of the time) or just lay it on the non-drive side if you really need to. they don't work on uneven surfaces and can sink into loose turf and fall. so if you have to hunt around for a place where the kickstand works, you may as well just hunt around for something to lean it on or just lay it down. also the front wheel can jack-knife after a while with enough momentum to tip the kickstand sometimes, which then crashes your bike onto the pavement.
the one you posted can better avoid these problems but they're more than twice as heavy than a standard kickstand.

>>2047514
agree in theory but
counterpoint:
I've only built two wheels but completely different specs.
I ordered all the parts online at the same time using mfr posted specs and an online spoke calculator. they both came out perfectly and I've put hundreds of miles on them so far.
so, it can be done. but if you have mystery parts or if they're old enough to not have specs online (or they're wrong) then you have no choice but to measure.
maybe I got lucky but I used companies I mostly trusted: Shimano and origin8 hubs (origin8 was the biggest question mark for me) two different DT swiss spoke types, and sunrim and velocity rims.
it worked.

>>2047510

There’s a few bike clubs near me but they’re only for rich people on Specialized, I just started practicing a week ago on a 500$ shitbike to get ready to bikepack in January 1st.

just want a place to chat in realtime and post images while on my rides, anons

>>2047554
I would make one, but unfortunately I'm starting to get the odd grey hair or two

>>2047539
I'm just warning that it 'could' happen. Of course you got lucky twice and will probably get lucky 10 more times. But shimano for example sold (maxbe still sells) two hubs that had the exact same number, looked virtual identical but the hole diameter was slightly off.
Used hubs is a whole new can of worms I agree.
So yeah, you do you. I just recommend you measure. The best idiot theck is sometimes putting the hub into the rim using a few old spokes and checking how much they stick out of the nipples and wether it aligns with your preconception.

yeah seems fine for the price
has hydraulic disk brakes which is a big + and the groupset is supposed to be a replacement for their other entrylevel groupsets

>>2047579
usually canyon is the best value since they're consumer direct but this has a Cues group on it, which is a new thing Shimano put out for the utility/casual/ebike crowd.
I don't know a lot about it but I don't think it's compatible with regular Shimano, which would wreck compatibility with everything else (sram, Microshift, other chinese brands) since they're all Shimano compatible.
it might be fine but I'd look into whether Cues is something you want

>>2047582
ya well searching "stp bike" all the results are that, with reddit number one so do you want to have everyone else understand what you're talking about?

>>2047585
So what are the downsides of cues being an entry level groupset? If it's just about weight then I don't care. I would be more worried if it was about reliability and gear range, for example.

Do I really need compatibility if it's my first road bike? In case I caught the bug I think I would sell this one and buy something better, I don't think I would be upgrading the shit out of this one.

>>2047587
what I can tell you is that the tech on the current lower-tier Shimano used to be the tech on their top-end groups if you go far enough back. you get nice shifting on sora and tiagra now.
does that mean cues is legit? I don't know because I haven't looked into it yet because I already have all the bikes I want. but I'd sure as hell read up on it if I were buying something new today. everything I know is just innuendo I've overheard here. my understanding is that it's a new system, somehow.
it should have you covered as far as reliability and range, would be my guess. whether it's overall "worth it" iunno. and worth it for you may be different than other buyers

Fellow bikechads, how do you deal with headwind? Is it just a skill issue where it eventually gets easier? A headwind is legitimately worse than hills in my opinion

>>2047591
lower the stem/bar as far as you can without pain over the course of your longest rides/tweak fit in general.
you do have proper saddle height, right?
ideally you should have some saddle-to-bar drop. if it's a drop bar bike, the hoods will have at least some drop compared to the saddle, then in headwinds you grab the drops and you'll really notice the difference.
if you have a flat bar or whatever, I believe there are some body tucks and grips, but don't quote me. I know there are some for road bikes but they look pretty weird.
look into aero bars, also. they're pretty cool although they wreck the overall look of the bike, but then again, so what?

>>2047591
get in drops, be stronger, deal with it

I do it by being a smol twink boy wid stronk legs

>>2047585
>I dont know much about it
goes on to speculate
Cues just wraps up all the former low tier groupsets into one. The idea is generally to improve compatibility. The discussion is moot regardless, it's delusional to expect the need to change around individual components on a bog standard road bike in the future:
-The bike is and will remain fine the way it comes.
-The value of a bicycle is not in the frameset. People who never thought about it just instinctively assume this as the frame is the largest individual part.
-You'll be paying alot more compared to buying the next tier up to begin with.
-You'll probably only worsen the overal package.
Just do a websearch for shimano cues and see what it's about and what not.

>>2047591
If that isnt your default to begin with reduce your frontal area when struggling in headwinds. It is okay to experienxe a detrimental effect on your breathing, the aerodynamics will make up for the loss in sustained power.
Everything else is a mental issue, as always when the going gets hard: Do not make the mistake to compare your speed to the speed you're used to. Focus on your level of exertion and maintain the effort you're used to. This will mean you'll drop a few gears and drop alot of speed. And that is okay. You'll fail if you try to hold the gear and speed that youre used to on that stretch.
Mental thing. Like hills.

>>2047618
>Do not make the mistake to compare your speed to the speed you're used to
I think this is the most important takeaway because I think this is my main issue. I actually go faster on hills than I expect because I'm already mentally prepared for a hill to be somewhat of a challenge, with a headwind, I'm still expecting my level straightaway speed to match what I would normally be going, so when I struggle to match that speed in a headwind it has a greater psychological effect as well as a greater physical effect since now I don't want to accept having to slow my role because of the wind. I think it's more about managing expectations

Finished a gravel race a few days ago on a gravel bike. My hands are still sore from all the vibrations (for a lack of a better word) from the unpleasant road. Anything I can do to alleviate that? My bar tape's thick and I wore gloves.

>>2047581
Shut your fucking mouth, most people wouldn't know. Stop being a wanker and just teach me another

>>2047621
You'll even get the physical effect, ex psychological effect:
People have a tendency to refuse to shift down and refuse to accept the situation. All of a sudden you see people groind at low cadence, even when they got gears left. This then burns you out fast. To make matters worse people will even try to put out more power than they're used to at less than ideal cadences.
Feel caught?

I have a newish 9-speed bike and lately the chain has been falling off when I shift up gears. Is there anything I can adjust on the derailleur or is it just bad shifting technique? I do tend to shift two gears at a time but it hasn't been a problem until now.

>>2047439 (OP)
Want to get into modding/working on bikes.

Came across a bike that looks exactly like this (brand says rhythm 00) but can't seem to find much onit besides people offloading them for around $30 to 50

Is it worth having as a starter bike? Mind you i haven't ridden a bike since I was a kid lol. I also volunteer at a thrift store so might occasionally come across broken or dumped bikes. Which parts are worth raiding to add onto mine?

>>2047659
25 is the going rate for 'random shitter that works'.

>>2047658
Could be a myriad of different reasons. Last time I had this problem on my 1x9 it was a worn chainring. A new narrow-wide fixed it.

>>2047659
just because you haven't ridden since you were a kid doesnt mean you have to pick the same size you rode as a kid. If I see someone riding bmx around town over the age of 20 I just assume they smoke meth

Thoughts on urban bike hire schemes?

I used to use them when I lived in London and I liked them.
>Comfortable riding position

>Don't have to worry about maintenance
>Don't have to worry about the bike being stolen - once you've docked it, it's no longer your problem
Having your own bike is probably cheaper in the long run, but you have to invest in good locks, and you have to worry about maintenance. Hire bikes are probably more convenient to be honest.

>>2047658
wait, you double-shift the rear derailleur and the chain falls off the chainring (the gear on the crank) ? and you only have one chainring or 2?

or it falls off the gears on the wheel and goes into the spokes, or off the outer side?

>>2047707
I use them all the time, they're nice as long as you don't think of them as a dependable way to get around. the issue they have is that the docks can't handle the flow of users in a way that would replace public transport or a car, so if you want to get to work for example, good luck with that because the docks by your office are all overflowing. but if you're just out at random and need to hop 8 avenues over and were going to just walk it anyway, they're nice

>>2047710
I used to use them to get to work, there was a dock near the office that would have empty spaces in the morning. I guess it depends on the location you're cycling to. Some locations will be very busy like you say.

>>2047673
if you are getting a bike so you can do freestyle tricks on it, or I guess take it to the bmx track (does anyone even do that anymore? its all DJ bikes now, right?) then absolutely get that type of bike. but I can't vouch for the robustness of a no-name bike taking that kind of abuse. so, no, don't get this particular bike.
>5'6”
for riding to get places, or going on pleasure rides, it doesn't matter that you're a manlet, that bike is still insanely small.
get literally anything else, but if you're riding around your city or town, we recommend a road bike, but a rigid 90s mtb or like a hybrid is ok but put on slick tires.
if you live rural or there's lots of dirt and gravel roads around you, you could get a gravel bike, or rigid mtb or hybrid with semi slicks or small knobbies.
for full on challenging off-road, you'll want a modern style mtb with at least front suspension and gnarly tires.
you're right about needing a bike that fits you, it's super important, because you need proper leg extension. pic related. this is way more important than the brand.
(continued)

>>2047709
It falls off the chainring, I only have one chainring. I think it's too early to be worn components (only 1000km on the bike) so I hope it's something I can fix.

>>2047715
Did you buy the bike new? 1x9 sounds to me like it used to be a triple and someone just removed 2 chainrings for the 1x meme. In that case your chainring is designed to let the chain fall off easily unless it's held in place by a front derailleur. Then you'll need a narrow-wide chainring, a front chainguard and maybe a derailleur with a clutch.
If you bought the bike new, it just sucks. Like most cheap 1x bikes.

>>2047714
on traditional style bikes where the top tube is horizontal, parallel with the ground, you can roughly eyeball your size to weed out stuff that will for sure not fit. you're looking for something that looks like this red bike. see how the two tubes are almost touching at the front headtube? this bike is probably a little small for you but you get the idea.
a little small can be tweaked although I recommend waiting to find the right size. but too big is not doable and can be downright dangerous as it won't handle correctly and you can't emergency dismount without destroying your nuts.

>>2047717
in contrast, this is a bike that fits somebody around 6'3".
using the size chart I posted will let you know, but this is just an easy way to narrow down all the choices.
modern bikes have sloping top tubes but they all have the frame size written on them, you want S, of course. the older bikes are sized like shoes in small increments, you probably want something around 50-52cm I'd guess. but they don't write it on the frame, you have to measure but it's easier to just straddle it. most sellers don't know the size, but if they do list it, then that's what you're shooting for but you won't know until you try a few. there's lots of size charts online but they all differ slightly so straddling them is the only way to be sure

>>2047716
It's new, cheap and probably does just suck. Should I just single shift?

>>2047715
you can buy a guide thing for 1x. or find an old front derailleur at like a co-op, clamp it to the seat tube, turn the limit screws so the chain is in the middle of the cage, and just not hook up the cable or shifter and just leave it in place like that.
also you can get a narrow-wide chainring like anon said.
just depends on how much money you want to spend and if you want an extra thing bolted onto the bike or not.

Also I already have a narrow-wide chainring now that I'm looking at them. I've noticed my chain feels pretty slack but I don't really have any frame of reference for what proper chain tension is supposed to feel like. It's not sagging but it almost is, should it be tighter than that?

>>2047725
it depends ™.
click the park tool link in the op and search for chain length, because if whoever built the bike fucked it up, that would solve your whole problem

thinking of picking this up (raleigh rx 2.0), $350
it's a size 52 and i'm 5'10, is that (too) small?

>>2047728
I think you're gonna have to let it pass on by, man

Chain guy here, how should I modify my shifting to avoid the chain falling off, is it the double shifting that's the problem or am I just pedaling too fast after hitting the shifter? I usually wait until I feel the click in the rear derailleur but maybe I got too aggressive and threw the chain off by pedaling early?

>>2047728
that should fit you
i ride a 50 at 5'6 and i had to get a slightly shorter stem because im shrimping too much

>>2047728
I'm 5'7" and 52 is usually too small

>>2047730
It's not the shifting "technique". It's the bike. I mean yeah, you could always slow down your pedaling and take all load off while you shift, but who wants to do that all the time?

>>2047733
Well I'm just trying to figure out the best way to make it not happen since it makes me feel like a retard. I rode an IGH until now so I'm still getting used to the derailleur. Is it more the double shifting that's the problem or pedaling too hard/too little?

>>2047737
How often do we have to tell you? Your chain isn't supposed to fall off ever, no matter how you shift. It's a mechanical issue.

>>2047730
you're allowed to shift multiple gears at a time. the way you soft pedal until the new gear engages is absolutely correct. you're not doing anything wrong, you need to get a chain keeper or the old derailleur thing here >>2047723

old forum lore from the dawn of the internet gets reposted and reposted and reposted and everyone accepts it as truth. a lot of it gets baked into the LLMs too

you see the same thing in cooking discussions, everyone says japanese knives will shatter if you look at them funny because 2 or 3 guys back in like 1998 bought a knife like that, and that got baked in as a fundamental truth of japanese cooking knives

>what kind of carbon
It really comes down to design optimization. If you allow a crabon bike to be as beavy as a steel bike its stronger in almost all if not all failure modes. If you want to reap the weight benefits and design the bicycle to be as strong as the steel bicycle in the cardinal load scenarious you'll find its weaker in some directions but a featherweight.

>>2047769
I don't even mean that, I mean like they were doing aluminum-carbon bonds everywhere and glued metal rivets and shit like that because it was new technology at the time and they were still figuring things out. I had an early carbon bike that simply fell apart on me, the frame separated into two pieces because a single rivet corroded into dust

they don't do that kind of thing anymore, even in the early 2000s there were still some issues here and there but in 2025 carbon bikes are as mature and reliable as any bike tech is going to get

>>2047707
heavy as fuck. 1€ for 15 min in cologne, I may as well take the train.
also if you park it incorrectly you get a fine.

>>2047777
Oh yeah I have a bike like that, it's got uninsulated alloy dropoiluts just bonded in, in direct contact with carbon fiber. The FD hanger is riveted into holes drilled into the frame. Etc.
I had to redo several of those spots over time just to keep her runniblng, until I made the toptube a biiiit squishy in a hilarious crash and couldn't be fucked to fix right away. So things went as always: Start to repurpose components meanwhile the incentive to fix the frame again drops further
Was one of the first Quintana Roo carbon models. Loved that thing desu.

Bought shorter spokes just to measure ERD.
LBS was closer if it was a 3 cross pattern.
What now? Shoot for what I measured (2 cross) or go for LBS (2/3 cross)?
My measurement is unreliable as hell, the ERD was off by 3mm from manufacturer's data.

>>2047810
>>2047810
So just to be on the same page here:
You took short spokes, the hub and the rim and laced the hub in a radial pattern into the rim, using 2 or better 3 or more spokes. You then, without outting and tension at all on it, wound the nipples down and checked how much of a gal there is to the bottom of the slit?
Or do you mean you just out two spokes with nipples in and you wanted them short so you can measure elbow to elbow? You know you can just overlap long spokes, measure and calculate the other way? Have you measured the spokes? Or do you simply trust they measure exactly as ordered?
What do you mean 'you measured 2 cross' and the LBS 3/2? This sounds alot like a rear wheel. Is it a rear wheel, I implicitly asked this before.
Also come on its not that hard to measure effective ERD to below 1mm but keep in mind the hoop isn't perfectly round so measure several spots.
Also the ERD being 3 mm off from official data means nothing. Who knows what they are communicating, nominal ERD, effective ERD? Using DT nipple? etc...
The important thing is: How repeatable are YOUR measurements.
So yeah this is confusing as hell please state what exactly what you want to know and what you're doing.
All you need to do is really: Measure ERD or effective ERD using YOUR nipples, measure your spokes and optionally your nipples, measure your hub and either do the trigonometry or bash it in a calculator that you trust. I recommend measuring effective ERD using your nipples.

Hello, this is my first time on this board. I am moving soon and will travel around the city on a bike, preferably with my chihuahua as well if that's possible.

I have two concerns, firstly being how to buy groceries for a week on a bike. If anyone has experience doing that: do you have a huge backpack? Also, for those with small dogs: how do you bike with them? Recommendations for very good helmets is appreciated. I apologize if this is the wrong board but I am moving in 10 days so I just want to have plan I guess when it comes to traveling with my dog and grocery shopping.

>>2047814
I don't buy a week's worth of groceries at a time, but back before WFH I used a steel commuter barge with ortlieb panniers to buy large amounts of food. now I have a 30L backpack. I like fresh vegetables and seafood so shopping like it's the night before the purge so I can eat out of boxes is not my preferred way to live

no comment on the dog

>>2047814
You can get panniers that will carry groceries for a week, but I suggest visiting the grocery store more often rather than stocking up all at once, it's more comfy. As for helmets, they are basically all on the same safety level at this point in time, so just find one that you like the look of, and get one with Mips.

>>2047817
I got a big hiking backpack, you think it will get the job done?

>>2047817
if you're on the bike a lot the extra money for a good lightweight helmet is worth it, I used to get those cinder block things because all I cared about was the vtec score but last year I finally started looking at weight and it is so much more comfortable

for a first bike and a first helmet though there are probably bigger fish to fry

>>2047812
I just followed what the park tool guide said with 2 spokes opposite from each other with a digital caliper for the ERD. I thought the E in ERD already means effective?

Measured it again and got 165mm spokes for 2 cross lacing pattern.
My LBS usually does a 2 cross lacing pattern and if I order the wrong length spokes, I could ask them to do a 3 cross lacing pattern if I follow their recommendations of 175mm spoke length.

>>2047814
I buy groceries every week on my bike.
you need a rack and either panniers or I use fold-out baskets. there are also similar baskets that don't fold up, they stick out all the time but some people don't care.
most people set theirs up on a rear rack but I did up front.
as you can see I've got a second rack and an upper, center basket for spill-over but the side baskets get almost everything.

>>2047818
if you can fit a week's worth of groceries in a backpack and your back can carry it all while riding a bike then you're a better man than I

>>2047823

>>2047825
Looks like a good setup, I dont know what my bicycle looks like because I got one for free from the people I rent the apartment from, so I dont know if I can put things on the back, the front or the side. Can those modifications be done to pretty much any bicycle?

>>2047825
do people ever hand you change or yell GET A JOB! while you're out and about?

>>2047826
for easy mounting, the fork and rear end of the frame need mounting eyelets. Without them you'll have to improvise by bending some brackets around the tubes.

>>2047820
Sorry my dude yeah Idk where I got my mind ERD is 'effective'. Meaning it depends on the nipples youre using. The 'gold standard' is a DT Swiss nipple so many numbers published for ERD are based on that.
Same question again: Is this a rear wheel? I am assuming it is.
>If I order the wrong length I can just have them do a 3 cross.
Do you mean if it turns out your spokes are the wrong size for 2 cross they must be the right size for 3 cross? Highly unlikely. But there is no need for you to order wrong spokes.
I repeat:
Measure the spokes. This means get a ruler that starts at 0mm, no offset or such. Thin metal rulers work best. Inspect your spoke make sure its decently straight. Hold the ruler upright, 0 at the top, hang the spoke elbow on the top edge, see where the end of the threads land. Are your spokes 165mm? Write down what you get. Repeat the measurement 3 times as you do with all measurements.
Spokes in two opposite holes. If using washers use them. Put Nipples on. Spoke end flush with bottom of slit. Calipers between elbows. Repeat 3 times. Repeat after rotating rim 90 degrees as it may be egg shaped.
Measure hole circle on hub. Repeat 3 times. Measure flange distance and flanke width. Measure from locknut to flange. I keep drawings of all hubs I ever laced into a wheel. Making a drawing can help spot measurement errors.
Read the instruction for the calculator carefully if using a software. Make sure you and the developer are on the same page what every dimension means.
Just measure carefully and calculate or use a calculator. Then buy what you calculated. It's simple. Cant go wrong. If you repeat a measurement 3 times and the readings are close together you're probably doing things right.

>>2047814
have a city bike with a baggage rack, buy a cheap bag like this, a basket or two and rubber ropes with hooks to secure stuff better
you can haul a lot of stuff

with dogs you want them in the front and obviously calm so they don't jump out

helmet you can get decent ones for cheap too but be sure it's certified

it's a lot easier in Europe I'm assuming you're American so I don't have specific advice. troll Amazon I guess

>>2047831
to reiterate, you basically put two bags of groceries in the sides or two crates of water, and another bag on the baggage rack, and then your doggo in a smaller basket up front so you can see him

just don't overload it and fall over

also another protip is get a bike stand like this that will be more stable and let you load and unload your bags without falling over 50 times
don't ask how I know

>>2047832
or this kind

>>2047826
there are aftermarket mounts you can buy if your bike doesn't have the eyelets next to the wheel axle for rack mounts. mine are made by Tubus, who also make good racks. but most racks will fit most bicycles. on my rear rack, I had to customize my struts at the top a little because my frame angles are extreme since it's a tall person frame. the front one fit no problem though

>>2047828
haha, only once. I was wearing my thrift store vintage parka because I thought it was hip, and I have a huge beard. I took my dog with me because she liked the exercise. so I'm locking up outside the liquor store, lol (I drink about a bottle every 2 months but I was out) and this rich black guy with a really nice, professional suit and really nice expensive shoes waltzes up and wants to give my dog the scraps from his to-go box.
I'm like "I don't really let her eat people food... " and then I realized, he thinks I'm a hobo.
fair enough, given the circumstances.

>>2047837
why do you not feed your dog well?

>>2047838
Human diet is nothing short of catastrophical for most animals.

>>2047831
Can you put these bags on any type of bicycle? I dont think mine is a city bike, it looked more like something a more invested person would ride, if that makes sense

>>2047838
she ate all she wanted, but usually only dog food. she used to love broccoli, too, so I figured that was perfectly fine. but restaurant food isn't good for dogs. probably not people, either, actually.

>>2047842
YOU HAVE TO BUY A RACK, THEN MOUNT IT. IT SHOULD MOUNT FINE BUT IF NOT THERE ARE ADAPTERS. THEN YOU CAN PUT WHATEVER YOU WANT ON THERE.
read the thread, jeez

>>2047842
whatever has a rack you can put those on

it's not rocket science it just hangs down from the rack

>>2047841
But you were offered nigger food?

>>2047707
They're good for one-off rides here and there, but as others have said, they're heavy as fuck. Even the regular analogue bikes are heavier than they should be. Don't even get me started on Lime Bikes. Especially bad in London where every cunt leaves em laying around and/or rides like shit.

>>2047673
Jesus, I'm a certified Turbomanlet at 5'3, and I wouldn't even bother riding something like that now, and as >>2047714 mentioned, you gotta have the correct saddle height adjustment.

>>2047714
How important is the tire choice, does having off-road tires tire you out more on roads from effic. loss?

>>2047852
>does having off-road tires tire you out more on roads
you got it.
I take my city bike with slick tires on dirt trails and gravel a fair bit, but mainly roads. they work just fine. I would only change them if I was mainly off road. the big knobbies are for mud and loose surfaces for serious MTB. there's inbetween tires but if you're on road more than half the time I don't think they're worth it.

How much benefit would i get for swapping out my handlebars for something higher and or more swept back? I feel like I'm hunching over too much for my liking

>>2047855
my bike came stock with drop bars but I put these on.
>>2047825
I like it quite a bit but on my fast bike I have drops.

What's something cool or useful I can put on a set of bottle bosses that doesn't have enough room for a bottle cage

>>2047862
a mini-pump holder

>>2047864
Eh I have a pump but I only take it with me on long rides and I throw it in a pannier

>>2047861
What's it like on your wrists? Do you feel it effects your turns much?

Hey /bqg/ I have a question for you, do you like to ride drunk or on drugs? Any stories you'd like to share? Picrel

>>2047603
post legs

>>2047862
I agree with the other guy, I carry my pump on my frame for every ride and it's nice

>>2047868
nah, it's nice. I got some chinese clones of Ergon grips and they're fantastic

>>2047876
How often do you use it, I pump my tires before a ride like once ever two weeks. If I take it with me it's because I'm paranoid about getting a flat.

>>2047868
you just slightly push the grip opposite the direction you're turning and hold steady with the other hand, it's nice.

>>2047869
I've ridden buzzed a lot and outright drunk more than a few times.
it's been mostly fine but a few scrapes a couple times.

>>2047882
Haven't used it on a ride yet because I haven't gotten a flat, but it's there if I need it

I bring with me:
Mini pump, tube, tube changer kit, 2 different hex wrench sets, crescent wrench, pliers, extra chain, chain breaker, zip ties, bottle opener, knife, 2 bungie cords, paracord, gloves, extra crankset bolts, U-lock, cable for U-lock, plus all my usual stuff in my crossbody bag chapstick money clip cards change etc.
Better to have it and not need it than to need it and not have it. I think outside of a catastrophic frame failure I'm prepared for anything. Except two consecutive flats I guess.. I might as well bring two tubes now than I think about it..

>>2047869
When I'm high on weed the last thing I want to do is ride my bike, but I have thought about riding down to some hiking spots, finding a secluded area and popping some edibles

>>2047909
get a tube patch kit
and fuck you need a fucking bottle opener for? you already got shitloads of things to open a bottle with

>>2047909
Why dont, you have patches?
I take patches and a tube. Flat? Swap tube, fix later. Another flat before the end of ride? Guess you gotta patch one now. At the end of a ride patch all tubes. Most tubes are more patches than tubes by now.

>>2047917
I have a bunch of patches too in the tube changer kit

i want to put a different wheelset on my bike but i dont have the tools to remove the casette
can i just swap it like this if the toothcount is the same on both cassettes?

>>2047928
Yes but the response was referencing >>2047909 where it specifically states that Anon is not prepared for two consecutive flats, hence anon wants to bring more tubes.

>>2047935
Yes you can swap it and the casettes do not havw to be the same. They should be within a reasonable window. More precisely: Your deraileurs capacity must be sufficient. Do a websearch for the term if you want to be dead sure.
Other than that naturally the wheel size, braking system and OLD should match and it's preferable if both wheelsets have the same number of gears.

>>2047935
>>2047941
theyre both 105, the casette from the newer wheels has the cogs spaced a bit different
put it in and it didnt make any noise so i decided to swap it
also got 28mm tires but there's only like a millimeter of clearance
can i run it like this? currently its rubbing a tiny bit because of the excess rubber from the mold
dont want to fuck it up cause its a carbon frame

>>2047439 (OP)
i have a 1980s road bike with downtube shifters on 105's, i love the bike so much, but i will probably want to replace it with a more modern bike at some point, will even the cheapest microshift groupset be a huge upgrade from what im used to? internally im constantly battling the urge to not spend too much while also making sure i get a "good" groupset, but also recognizing that even the worst modern components might be an upgrade

>>2047940
Yeah I forgot I had patches in the kit so it turns out I am actually prepared for two consecutive flats oopsie

>>2047942
>>2047942
>They're both 105
>cogs spaced different
I am now assuming you got indexed shifting and you have no way to turn the indexing off to get friction
A different number of gears would not be a problem, you'd just adjust limit screws so the chain can not fall off if needed.
Different spacing is a problem with indexed shifting because your shifter has a fixed amount of cable pull per gear, this moves the deraileur a fixed amount.
>Picrel
Is a carbon frame of mine. It never rubbed but all the shit (road bike) that gets sucked through there can eventually wear the paint. This exposes the composite. The composite we see today is often designed to be relatively dry aka designed to have a matrix deficit. As such I am worried it could draw water when exposed but I have no source nor data on this actually being the case.
Why do you want to run 28s? Is it just what you had on hand?

>>2047909
I have more edc on my city bike than most people, but Jesus Christ. extra chain? chainring bolts? bottle opener? just use the lighter trick, you can use anything not just a lighter .

on my fast bike its just flat repair stuff, the lightest multi tool on the market (I constantly fiddle with my fit in search of perfect optimization,) a packet of cheese&crackers, and phone

>>2047917
this is the correct answer

>>2047947
I have 1989 105 derailleurs and I swapped the dt shifters for 7 speed Microshift brifters which are not the flagship model.
the shifting is acceptable. you click it and the chain goes where you tell it. it's not the smoothest shifting I've ever experienced, but I like it fine and have absolutely no regrets.

>>2047955
i had a look again and even counted the teeth and the cassettes are the same, and i didnt mean the spacing but the rotation of the individual cogs
>why 28s
it's all cobblestone here and while 25s are okay it still vibrates quite a bit
going to keep using 25s, this is an early 2000's monocoque carbon frame so it probably wont hold up to that kind of abuse

>>2047960
>wont hold up
your bicycle will deal with rolling on 23s. If it doesnt your bicycle will not deal with bicycling. The difference your tire choice makes in scenarios where your bicycle experiences maximum design forces is about nill.
>cobblestone
>vibrates
thats just road bikes desu. I'm not saying you are me or anyone else but desu 23s at 8 bar are absolutely fine for use on cobbles and gravel roads IMO. Again: I'm not you and maybe your experience is different but I'd say just try it and see if it's just a mental issue.
So same number of gears? That implies same spacing and same OLD too (in general inb4 obscure parts) and you're good to go. It should shift, likely without any adjustment.
Regarsing the clearance: Your choice. Like I said the paint may suffer and eventually disappear. But you'll be fine. IMO the whole 'pebble gets sucked up, wedges in there, locks your wheel and over the bars you go' is a load of BS. Rode many miles on bikes with virtually zero clearance and things either dont get in there in the first place or just pop out the other end (after damaging your paint)/and in case of the front a stone might actually end up in the steerer causing a racket.

"Saddle" sounds so cringe and LARPy, when I was a kid it was always called a bike seat.

>>2047978
When you were a kid, everything fucking sucked though.

When I shift, my chain falls off the chainring at random times. Is this something to do with the limit screws and/or barrel adjuster? The chain itself is pretty new.

>>2047987
try tightening the limit screws to as central as possible but the chain just barely makes it to the target ring. but if it rubs edge it a little looser until it makes the shift and a tiny bit more so it doesn't rub

>new Canyon gravel bike with Deore XT Di2

Is GRX going away?

>>2047978
Way before you were a kid, some German guy called the seat a "saddle" because the machine was meant as a replacement for the horse.

>>2047978
Ok, thanks for sharing. Now lets hear your opinion about the way clipless pedals are named.

>>2047988
are you trying to advise anon to turn his bike into a single speed? KEK
>>2047987
Anon this shouldn't happen. Even with the barrel adjuster set wrong. In which case it would never shift but instead just be noisy as the deraileur tries to push the chain over but never does.
The limit screws would only be a suspect if the chain fell of the largest or smallest cog. I assume from what you wrote it drops on random shifts, even in the middle?
You wrote the chain is new. Is it too long? You did shorten it appropiately, right? In the smallest cog, is there still at least some amount of tension on the deraileur cage? It did shift with the old chain, right? Your chain and cogs pitch might be helplessly mismatched due to wear. Post a pic of your rear cluster.

hobbyfags are stupid

bikenoob here. I got back to running again. I also cycle (not as much but harder/more sprinting). I noticed that when stopping at stoplight I can easily use my left leg to stand and hold it. but if I try to use my right leg to maintain balance I just can't do it long, I also have trouble lifting my butt up to the seat and stay there this way.

what are some great fixes for this? obviously I know just "practice" standing on the right leg works, but it'll probably take so much time. I want to spread my asshole while standing on the right legs EFFORTLESSLY

>>2048085
you're not enjoying things, you're drowning in excess, escapism and consumerism.

word cyclist has been contaminated by people that make these things a substitute for their personality.
it's the same difference as being gay and being just a normal dude, Vs wearing rainbow pins and draping yourself in mental illness flags and dancing naked in front of children on parades made by old white politicians to farm brownie points.

you don't want to associate with that.

>>2048076
Because it makes no sense to compare the price of a new bike to a used car.

>>2048086
sometimes I forget that there are people who are biologically incapable of enjoying anything. I remember after that incel shot up a school in new england they leaked his school paperwork and basically the shrink's assessment was like his brain is so broken the only emotions he has ever experienced are negative

maybe euthanasia would be appropriate for people like you

this is also for you.

What do you call these rigid shifter cables? It comes from an old sport bike with an indexed rear derailleur.

>>2048312
It's a Shimano Positron rigid cable, sometimes described as a piano wire. I would not bother sourcing one, you'd be much better served by replacing the shifter, derailer, and freewheel, both for immediate performance and for long term serviceability.

>>2048111
The only thing I actively dislike on the 2 model is the FSA crankset (stupidly heavy, BB and chains not compatible with anything else). I think which you should go with depends on whether you're planning to make immediate component changes or not: the 0 is a really nice build straight out of the box, but if you already know you're going to change things out you might start with the less expensive model.

Found a giant contend 3 for a bit cheap than usual at 700 dollars. It has rim breaks and want to upgrade the other parts at some point. Is it a good deal? Want to do long distance riding and want something fast but not beyond 800 dollars. Its new as well.

>>2048343
700 and 800 euros*

>>2048335
>It's a Shimano Positron rigid cable, sometimes described as a piano wire. I would not bother sourcing one
Thanks a lot. I wanted to only replace the housing, but that doesn't seem to be possible and I can't find a "new" one in white...
I'll reuse the original for now and. It's a friend's bike who asked me to repair it for him. If he actually ends up using it (kinda doubtful), I'll recommend spending money on a more modern group to him.

Opinions on cheapo China brifters for a 90s rigid MTB drop bar conversion?

>>2048343
That's a very basic road bike, nothing fancy or modern about it, but nothing actually bad about it either. For a new bike it's the cheapest I'd ever go with, anything below that price will be junk. If you want something cheaper but still good you'd need to look at used bikes, with all the complications that come with buying anything used.

>>2048347
I'd go with the Microshift levers these are clones of instead, it's worth paying a little extra for reliable warranty coverage. Otherwise these cheap levers are perfect for a project you're putting together for grins.

>>2048347
drop bars suck on mtbs
get barends if you want diffrent hand positions or buy a cheap road/touring bike

>>2048347
>>2048352
do not listen to this retard
there's people putting dropbars on mtbs for a reason
gravelbikes are becoming more and more like mbts for a reason
i dont know anything about chinese groupsets but the guy from tracevelo really likes the L-Twoo groupset

>>2048353
>do not listen to this retard
I've been riding enough different bars to know why I want drop bars anyway.
>i dont know anything about chinese groupsets but the guy from tracevelo really likes the L-Twoo groupset
I bought a set. The seem to get decent enough reviews.

are these good?
have a few spots where the cables are rubbing through the paint and one big chip i want to cover up

>>2048351
tasteful goatse reflector

I have blood on my gooch after I ride what do

>>2048405
Seek medical attention immediately and not internet advice since it sounds like you're bleeding out of your rectum (I presume that if you had open sores/wounds, a burst hemorrhoid, or were a woman on her period you would already know where blood is coming from).

>>2048409
Never thought I'd get that literally butthurt

>>2048351
Found another contender but its an ar type with disc brakes and carbon fork, seems lighter for 100 euro extra at 900 total. Sounds good for a road bike that doesnt reach 1500+ euro price right?

>>2048414
Actually its 1000+ euros should had checked the price. So the contend 3 is just 880 euro and ar is 1090 euro.

>>2047869
I always ride the bike and im absolutely shitfaced most nights, especially on weekends. So yes. Doesn't bother me. It does become harder to hold a line and often you need all of the road or a bit more even but that's not an issue at night.

>>2048360
Should be fine. I used generic helicopter tape from Ali express and it's held up for years.

This one looks kinda cool with decent components…maybe worth $250 on a good day?

>>2048360
Yeah, pretty much essential if you ride enduros or DH bikes. If anything, they are overkill for your purpose.

I have a bike that spent 3 years outside that I want to fix up, preferably with minimal investment, I don't own any bicycle specific tools, it's a steel-framed commuter bike with internal gear hub in the back, a dynamo hub in the front, V-brakes front and back as well as coaster brake, what do I likely need to change?
>Tires are dry-rotted, no idea if they hold air, seem to be tubeless
>Some broken spokes, wheels aren't true but not terrible
>Shifter handle is broken
>Chain is not rusted, only rust is on handlebar and some bolts

I have never fixed a bike before but I'm not interested in paying some shop to do it, how much of a pain in the ass am I looking at?

>>2048465
First of all, check if you can move the seatpost and stem at all with the bolts loosened. If they're rusted in place, probably not worth the effort to even begin. Then take off the chain, check if the crank, steerer, both pedals and both wheels rotate freely. If yes, buy new brake pads, new (or used) tires and tubes, use chain cleaner on the chain, properly dry and re-lube it, lube the cables, rebuild the wheels with the right length of spokes and check the bike for missing or loose screws, bolts and nuts.

bikenoob her.e I just realized what a fucking improvement it was to just increase my saddle height by a few centimeters (maybe 1.5-2cm?), then put it forward for like few millimeters. what the fuck? I have way more power now. my testicles dont hurt (that much) anymore. ??? the fuck??

before anyone telling me im DUMB im NOT. the previous position was already "okay". I just didnt tink just very tiny changes could be so easily felt

>>2048405
after you see the doctor, check that your saddle is around the correct width for your sitbones, it's level with the ground, and at the proper height >>2047714
and the rails are mostly centered in the clamp.

>>2048470
After riding my bike for 3 years and just dealing with the discomfort cause it's "aggressive geometry", I lowered the saddle by about 1cm and suddenly all my issues are gone.

I have somehow scratched a little on my tyre and a small peck of carbon from my wheel. Should I be worried?

>>2048482
press on the carbon with your fingernail
if its soft the rim is done

>>2048486
It is very rigid and not soft. Can I do anything to strengthen it? What about the tyre?

This was my bike as a kid. I'm just curious what model this was but I have no idea what it reads... JQIQQ?

Pls help!

Also thoughts on it? I remember cruising this thing all the time

>>2048482
The damage to the rim looks superficial. There isn't really anything you can do to "strengthen" it, only fix the look by using something like composite resin and retouch it with a matching color.
Concerning the tire... no idea. I don't think it's problematic.

>>2048495
I see, would nail polish or epoxy be a thing then for the scratch?

>>2048460
jusys christ
why are american bike prices so fucked up

>>2048494
I'm not sure that this thing is actually a Schwinn. I can't find this geometry in any of their vintage kid's bikes.

>>2048496
Yeah. No guarantee that it won't flake off after a while, though.

>>2048499
Understand, I will do something to cover the scratch and monitor my rides and see if anything changes. As mentioned before, the stiffness is the same from what I can "feel"

>>2048497
Ahem

>>2048494
it's a Schwinn Jeda.
quick search was all owners listing it, nothing official.

>>2048501
that looks more like a museum piece.

>>2048503
It's a Steyr "Waffenrad", they can date way back into the 30s. My parents own two of them that have swastikas stamped into the frames.
This price is still dumb, though. They're a pretty common find in barns and cellars in this area.

>>2048497
Id consider it for $200 with lights and lock included

>>2048512
you live in a very different world.
if it was a really good bike and lock I might have considered it for like 60-80 euro, but I wouldn't buy a single speed without a baggage rack probably cause I'd have no use for it.
but also because I could have bought a lock separately new, and a bike for cheaper anyway.
but it's probably cause it's incredibly easier to find these things where I'm at, and people might be giving away bikes for free or just throwing them out not to take space up.

>>2048513
Yes, I live in New York City and you probably live in some village in yurop with no cycling culture and thus zero demand

>>2048414
Whether that's a good deal or not depends on the specific model. If you can get one of the models with hydraulic disc brakes for that price it's a great deal.

>>2048460
seems overpriced considering that the used market is flooded right now basically everywhere

>>2048470
1cm to saddle height is big change since that's more than 1% of your leg length unless you're a giant

>>2048523
The cheapest version at 880 has rim brakes while the AR version has mechanical disk brakes and carbon fork for 200 extra. Normally the best option would be to save more money and get a other model at 1800 euros but giving that much currently doesnt sit too well tb h.

>>2048521
how does that make sense?
cologne btw.

>>2048497
a lot of americans have this idea that bikes that look "fast" are bad and they need to pay extra for shit that looks like barely rideable garbage, there is a whole industry around this mentality

>>2048523
what anime is this from?

>>2048545
That’s true, but the listing I posted is just some delusional guy who thinks he was a “rare” “vintage” bike. Someone probably scammed him and he’s just paying it forward

>>2048576
maybe or maybe not, but I guarantee you if you were to put that piece of shit up next to offering to build them a fully bespoke mosaic or an appleman for the same price, 9 out of 10 NPCs are going to go for the piece of shit and would actually offer to pay more for it because it looks more twee and bookwormy and goes better with their strand bag and non-prescription glasses, unracers are profoundly brain damaged people

>>2048585
Yeah, some people like a more “classic” aesthetic, especially for a bike that’s just used as a commuter or beater. I’m one of them.

Using shims to clamp 26mm aero bars to a 25.4mm bar:
Ill-advised?
I'll make sure to sand the beer can pieces for a grippier texture

If I wanted to go tubeless with my 90s rigid 26" MTB gravel conversion, what kind of wheels should I look for? I don't expect to find tubeless-ready 26er wheels, so I'll probably have to convert some. What type of wheel should I use?

>>2048608
Never had a problem with shims. I always used real ones, though. No beer cans.

>>2048629
>I don't expect to find tubeless-ready 26er wheel
why not people ran tubeless 10 years ago

https://www.velocityusa.com/product/rims/cliff-hanger-559

>>2048632
True, I didn't think of that.

>>2048632
>>2048634
Welp, they aren't available in Europe. Not if you want compatibility with rim brakes, it seems. Looks like my only real option remains a tubeless conversion.

What's the correct torque for the brake/shift cable clamp bolts?
They are either loose or fray very quickly.

Has anyone made a bicycle mechanic portfolio? I live in a outdoor recreation town and I am applying to a fairly respected bike shop. I've been a mechanic for over a decade, but it's been home shop or bike coop work. Never professional-tier.

Just want to list out my skills so they know I've touched bikes. Not really sure where to start, listing everything out seems tedious.

>>2048662
I used to work at my local shop, I would say just list what your experience is briefly, no need to go into big detail. They're going to evaluate what you know way more by actually having you do stuff than anything you say or put on a resume.

>>2048671
nta but how much would I need to know to start at a bike mechanic shop? like I repaired and serviced bunch of bikes for a year, but I don't have any education for it and I'm on Germany where these things might be more autistic. for proper one you apparently need to learn 3 years and that feels like a waste of time compared to just being a helper for a while and getting knowledge directly

>>2048684
in germany they employ people with mental disabilities in bikeshops
you dont really need to know anything

>>2048657
You really don't need much. New cables also stretch quite a bit, which people are sometimes misinterpreting as slippage.

>>2048687
with mental disabilities and an Ausbildung. probably.

>>2048687
Yes, those people either have done an apprenticeship for 5 years (cause they couldn't do it in 3 due to their retardation), or they are basically there to give them some structure in life, so nothing is expected in terms of work load and they're exempt from minimum wage cause they live off gibs anyway.

>>2048684
You used to need a 3 year education. Now if you show up in spring, they'll hire anyone who knows what "counter-clockwise" means. Thanks to "Fachkräftemangel" (i.e. exploded rent prices in cities).

>>2048684
How much experience/training you need really depends on the shop. Your best bet would be to go and talk to the owners of whichever shop you'd like to work at and ask what they would expect out of a bike mechanic. It could vary greatly. One shop might have a lot of workers and some experienced techs who you can apprentice under, in which case they might be willing to train you mostly from the ground up. Some shops might need you to come in fully trained and ready to take over all their bike wrenching. Everywhere is different and getting to know people in person trumps any resume or certification.

>>2048701
neat

>>2048704
makes sense

thanks my diggas

Why do I need to push the mineral oil with a syringe from bottom to top when bleeding Shimano road brakes? Every tutorial on the internet, including Shimano official manual, tells me to do it that way, but nobody explains why.
Why can I not fill the funnel with new oil and let the old oil drain out the bottom? That's how I did it with my MTB brakes and it worked fine. Why the need to faff with the syringe for road brakes?

>>2048719
or just use normal brakes that last for 30 years

>>2048720
not only do rim brakes last longer
they are also lighter and easier to service
disk brakes are a meme

I'd really be appreciative if someone could just give me the 411 on basic shit for my carbon bike so I can try to repair this. (Planning on replacing Chain + Tires + Cassette (far future though)

I have fucking no idea what to do for the cassette or tires. I know I need a torque wrench but fuck I'm reading online and it's buy this torque wrench no buy this one no buy this one no you actually need two. holy fuck this is so confusing...

>>2048870
You have a carbon fiber bike but can't afford 20 bucks for a pair of pliers?

And yeah you probably need two
I have a low range one for fasteners and then a regular 3/8 one for cranks and cassettes

>>2048902
>can't afford
no my issue is I have no idea what the hell to buy and what the hell is snake oil.

>>2048903
>see a tool in a park tool video
>order a clone off aliexpress
I mean it's a piece of pipe or something similar, not that high tech

>>2048870
>Planning on replacing Chain + Tires + Cassette

chain: you need a chain tool to size a new chain to the gearing on your drivetrain. the tool slides the rivets in the links off and on. you put the chain around your biggest gears front and back but not through the rear derailleur, then you add link(s) to account for some length when you run it through the rear derailleur. up to 9 rear cogs is just one extra but you probably have more so probably 2 but I'd check with Park or whoever.
also more than 8 speeds you need a specific chain as well so buy what matches what you have. one of the links you add can be a quick link if you want. some need pliers depending on design.

tires: you can sometimes just use your hands with a particular technique but if not then you need tire levers. mostly they're all the same but if you happen to get super tight bead tires (also rims can have an effect here) then it's really difficult. for that, the only ones that worked for me were Pedro's levers.

cassette: against the smallest cog is a flange that screws down against it with splines inside it. you need a cassette cracker that fits your spline pattern e.g. Shimano. some other brands may be compatible with Shimano, I don't know. once that piece is off the whole cassette just slides off the hub no problem.

>>2048870
>>2048927
if you happen to own a bench or angle grinder and have an extra set of pliers you don't use, you can grind them down to make quick link pliers

>>2048957

Are the pedal system, the pedals themselves, or the shoes to blame ? Right now I'm betting on the shoes themselves, but I'd rather not drop money on yet another pair if I'm going to have the same issues again.

>>2048990
Or alternatively, was I just fucking up my cleat mounting and it's a solvable problem I just never managed to solve ?

How do you assemble this old Shimano front derailleur? Seems like the shifter cable housing is supposed to end at the blue circle, then the cable is clamped at the orange circle as usual. But then theres the little metal thing in the green circle that seems to be used for clamping the cable. I can't figure figure this out...

My chain is skipping after I replaced rear wheel and chain. The cogs are the same. The axis on which the cogs go is longer than on previous wheel so I padded out cogs with rubber so they don't move; I also realigned the rear derailleur and it seems to feed the chain properly onto the cogs. Could it be my chain is too long?

>>2049012
>axis on which the cogs go is longer than on previous wheel so I padded out cogs with rubber so they don't move
this sounds like trouble to me. one end is padded or you spaced them out individually? individually would fuck the shifter pull. spacing from one end may or may not work, but I'd use a hard metal spacer, rubber is going to flex and fuck up the shift.

otherwise, is the cable clamped according to proper procedure? you turned the barrel adjuster towards the cogs that weren't catching?

I taped an inspection mirror to my helmet to use as rear view, but when I went for a ride today it made me motion sick. Does this go away? Do I just have to get used to it?

okay did my tires only to learn my gp5000 s are the wrong way.
is this okay or am i going to explode, online im just getting meme answers or "acktually you're going to lose 0.05% efficiency"

>>2049039
may or may not have a tiny affect on aerodynamic drag. otherwise it doesn't make a difference what way they are mounted.

Question for longer bike rides, how do you guys keep your dick and balls from going numb/falling asleep ?

seems that after about 12 miles the ol twig and berries go numb.

/bqg/ discord: https://discord.gg/SvvHasUd

someone had the idea for one so I made it

>>2049012
how stretched was the old chain? the new chain should've been set to the same length as the old chain.
it's possible your cassette is getting worn out. because the new chain isn't stretched out like the old chain it won't sit in the cassette cleanly and can start skipping. that's only for very worn cassettes though

>>2049010

>>2049048
why?

Was doing weekly maintenance on my bike, and noticed some strange cracks (?) on my front wheel rim.

When I run my finger over the visible line, I feel nothing, everything is completely level. But when I use my fingernail then I can feel the crack.

Is this somekind of a paint crack? Or do I need to replace the entire front rim to a new one? About 1 500 km rode on this one-year-old bike.

>>2049158
Here's a different visible crack or whatever this even is. I'm more worried about this, as this one seems to run through spoke hole. But still the only way I can feel this is by using my fingernails; otherwise it's completely flat.

Rim info (found on a sticker on the rim) is:

Ignore "supposed to". Just figure out what needs to pull to shift and work backwards.

>>2048870
Look at more complicated multitools and simple all in one toolboxes for an aproximate range.

Tires are some tire levers, how many you need actually depend on how strong you are. Tube. And whatever you need for your wheel nuts. Probably basic wrenches or QR.

Chains is chain breaker. Chain checker you can sub in a ruler, but they're dirt cheap.

You need a basic torque wrench because you have CF and if you go at it like a mong, you crack shit. You only need one.
