I get this zzzzzzzz sound while pedaling hard-ish coming from below me, its kind of a rear hub buzz, but it happens lets say when my pedal is in the up position (not constantly, but a during a period during each rotation of crank)
I am thinking its bottom bracket cus the noise seems to match the cadance and not wheel speed, but the noise isnt exactly a creak like I have seen online
its not the rear derailleur
could it be the chain? or maybe pedals?

how do I know if my mech brakes are shit, or just need adjusting lmao
