Can someone tell me how there are xtr cranks in the green yo eddy from the for sale forum ("has this bike ever been ridden" or something like that.----is that a kook move? i have a yo i am going to build up and happen to also have the xtr cranks that were for a different project. What bottom brackets are recommended and where do i find it...dave ------------------------------------------.my bikes .2 fats: yo eddy from my past: 484y1s -and- another yo I picked up used: 823y1m
