Anyone know if this combo will work? The description of the XTR bb is somewhat vague saying it will fit the XTR crankset however doesn't specify if it will work with others.

It's really for color matching as the XT bb is grey and doesnt work with what I'm doing. Plus the Shimano BB's are close to 45g lighter than the Raceface 83mm bb's with terrible bearings.

Is there a difference between the XT and the XTR BB? Other than the $5?
Thanks!

Same part.

100% works, i'm actually running this exact combination on my Sunday, as I had a spare XTR BB & didn't want to use the junk RF one.

strange.......The X-type BB on my 3 year old Diabolus cranks is still smooth perfection, and my X-type BB On my Atlas freerides (one full season) are perfect too. I ride 6 days a week, I am 195, and I live in wet muddy Eastern Canada. All the perfect conditions to kill BB's prematurely.

Obviuosly the XTR BB must be lighter.

The new RF BB cups are much better. They fill the bearings with Phil Wood grease at the factory.

none of my RF BB's last more than a year. all feel like total crap after a full season of riding and make a fantastic grinding noise
