XTR M-952 crankset BB alternatives.
I'm looking for a possible alternative to the M-952 BB that's used in conjuntion with XTR-952 cranks. From what I can tell, the only choice I have is the XTR BB. I'm building up a secondary bike and don't want to spend alot of $$ doing it. Is there a BB that's compatible with the XTR 952 cranks that doesn't cost as much ?
Nope. That's the only BB that will work with those cranks with one caveat...the splines on the road BBs are the same pattern. Octalink V1. They are different spindle lengths and only available for 68mm shells.
If your frame has a 68mm BB shell, you might get away with using the BB from a road triple crank such as a 105 or Ultegra. The spindle is 118mm though and the XTR crank is designed to use either the 112.5 or the 116 mm spindle...it's only 2 mm though if your optimal chain line calls for the 116mm XTR BB.
Thanks Nater...good info.
