Pros: Stiff and relatively light for a 3 ring crankset. Crankarms take a beating and walk away with minor nicks. The middle ring lasts a LONG time.
Cons: Chainrings are expensive to replace and the granny wears quickly.
Recommendation: If you have the $$$, make the purchase. You won't regret this one. XT stuff is the non-sponsored mtber's go to gear for good reason. It's nice but not so nice you need a logo on your back to afford it.
