can anyone tell me what should be the correct spec sizing for the following items? i'm transfering a 2002 XTR (FC-M952-4) crank from my previous bike to a Blur frame.

Bottom Bracket: 68mm x ? (length?)
Cassete: what would match for 46-34-24 crank?

alternatively, i was thinking of just purchasing the 2004 XT (FC-M760) crank instead. it has the integrated BB so lenth and size would not be a problem. since the XT crank is 44-32-22T, what cassette should i use?

thank you!

What would be the effect if I had a 11-32 cassette instead?
