Currently using a pair of 29x1.95" slicks.

I want to build a new bike, but with 27.5" x 2.3" slicks, if it's even possible to find such a thing in Aliexpress.

What I actually desire are 24 x 3" but it seems almost impossible to find a combination of forks/frame/rims/tires that would be adequate.

I don't want a fat bike. I want something that has wider tires than what is available for most regular bikes, but thinner than fat bikes, which look horrible.

Would it be too stupid to use 24in rims on a 26er, then use 24 x 3 tires on the 24in rims? Assume I have disc brakes.

Goal is to have a skinnyfat bike.
