XTR bottom bracket really tight?
I just picked up a new XTR bottom bracket for my M960 and the bearings seem to be really tight. The cranks will only spin 360 degrees with a solid shove. Is this normal? Do they loosen up quickly?
The Shimano BB's are very tight out of the box. They are also very well sealed and seam to last damn near forever for some people. It will loosen up a little bit but if you want something that spins more freely your going to have to look outside Shimano, the Chris King BB's are tits fwiw.
You did put the correct number of spacers in didn't you?
