Man I am losing my mind over this one. I've tried to search but can not seem to find the answer. I have an older XTR 952 crankset and I am using it for a single speed conversion project. The issue that I am having is the chain keeps droping. After looking at the chainline it appears that it might be off by a few mm's. If I were to go with a shorter bottom bracket it seems like that would fix the solution since the chain line needs to move inward a hair. Unfortunatly, the smallest they make the XTR M952 bottom bracket is 112. My question is two part. Would playing with the 2 spacers and moving them around to one side or the other or taking them off make a difference? Can I use an Ultegra, which comes in 109 with the XTR cranks? My shell is 68mm. Thanks for any help, I really want to use this set-up. Lee.
