Just wondering what size bb people are using. My old xtr cranks are 112.5 and look like they wont work. A buddy is using a 118 and had to do some grinding. I am using a 135mm rear wheel... Also, the bikes axle is not looking to good. I am going to use my old one I think. The new one sticks out a few inches and the threads begin before the axle gets to the frame? Thanks ahead of time.
