I've got a m760 XT crankset and bb that's had about 1.5 years of riding on it. It's gotten loose. If I grab the crank arm (either side) and the frame there is play. This is very noticeable when pedaling hard.
1) Do I just need a new bb?
2) If I do need a new bb, will the old external-type FSA bb that came with my gossamer rd crank work?
