BB and crankset fitting
Hi, I'm building my fixed gear and I wanted to know something about bb and cranksets. My frame suggest to take a 106 to 108 mm bb. In this case, I wanted to order a 107 mm bb which can fit most of cranksets. The problem is that I don't know if any cranksets fit with any bb. In fact, I've seen some fixed gear bb that fit 103 mm. I wanted to know if it changes something 'cause 107 mm cranksets aren't that easy to find... I thought any cranksets would be good as long as you have the good bb length for your frame (in my case 107 mm). If so, I'll order a 107 mm bb and a crankset of 103 mm 'cause it fits well with the design.

Thx for the answers
Look at plus what he wrote about chainline. Plus you have to make sure it is the correct thread (if you use a reasonably new frame it should be ISO).
