I came from a M960 XTR group on my last bike to a M760 XT group on my current 06 RX100 and can tell no difference. Cost way less, a little heavier, works just as well, last just as long (or longer?? IMHO) Only 70 grams difference between the cranksets, and XT uses a normal spline pattern so you are not commited to shimno rings. Good Stuff
The M960 XTR cranksets are on sale right now at Jenosn for 299 which seems pretty good.
Good luck with whatever you decide
BTW why do you think you need a new one, and what generation do you have now???
The XT M760 has one of the widest Q factors of all the Shimano cranks. Not sure if that matters to you. I ride a lot of road and wide Q just feels strange to me. For that reason I kept my old school M952 XTR cranks for my new RX100.
Q Factors of new XTR, new XT, old XTR:
I ran XTR on an RX 100 that I recently replaced with a ML. I went XT on the ML and have a hard time noticing a difference. The XTR rings are very costly and proprietary to save only 2 ozs. I also am running Race Face Deus XC on a second bike. I feel the rings are very fragile compared to the XT and I have had several times when the crank arms loosen up despite using correct torque and locktite. I know others have had similar experiences. The weight of the RF is very close to the XTR though.
If you can't wait for the 2007 model, search on eBay for a good $300 offer. Shimano XTR still remains as one of the lightest cranksets (FSA Carbon just look good but they are HEAVY) and one of the best on the shifting department.
