I just ordered a Carbon Rush 2 and didn't give it much thought that the crankset was carbon with the plans of putting in my XT crankset. However after doing some "after the fact" research I noticed I need an adaptor to fit the XT cranks. The SI are a bit lighter so I wouldn't mind keeping them but am concerned with durability. Mostly with striking the lower crank arms on rocks, since we do have a fair share of them here in Pa. The bottoms of my XT's will prove that I am not always the best at timing...
So how well do the carbon SI crankset hold up to the ocasional rock bash?
I remember a while back I seem some Bontrager Carbons with an alluminum cover over the bottoms, seems like that may be a good idea.
