The numbers you're probably referring to are the chainring sizes. 44/34/22T rings are typical, although you may see some OE models with 42T big rings or 24T granny rings. Whatever they are, they'll work with your bike.RyanCanfield said:well what do i need to mesure so i know it works?? i see these numbers like 45/44/43 or sumthin. thanks
The new XT and XTR with the external bearings have come with everything you need. Otherwise, you'll need to purchase the crank and bottom bracket separately.RyanCanfield said:does the cranksets usually come with a bottom bracket? or are those seperate. and also, i could buy a standard crankset and it should work if i just leave my BB the way it is. how do u remove a bb? thanks for all your help

If you buy a square taper crankset to fit on an existing square taper spindle, there's a good chance it'll bolt right up and work with minimum adjustment, but the square taper interface has a bit of imprecision in it, so there is strong chance that a different brand or model of a crank will seat differently on the tapers. Often it'll be "close enough", or adjustable with spacers (this is all assuming you have a cartridge bottom bracket).
You remove and install the bottom bracket with the BBT-2 tool and a 3/8" ratchet or breaker bar.
