    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.

    Not sure how much help I'll be since mine has the 150mm rear wheel, but I run a 128mm bb and 175mm Holzfellers...

    If you search on here there are some old threads from when the M3s first came out where people were having spacing issues as well...

    You need to go with a 128mm BB and 165 or 170mm cranks.

    Is this it? Or at least colse to it?
    If you can't find an XTR size that works I believe that the will also work. There are other sizes available, this is just the first one I saw.

    Now put the pipe down and get to work!
