I'm thinking of upgrading the Hollowtech I, Deore 3 piece cranks that came on the 07 Stumpjumper I recently purchased. I'm looking at some Shimano XT cranks on ebay, Hollowtech II, two piece. I noticed some have the original Shimano chainwheels, and some have replacement Raceface chainwheels. So my question, is the quality of raceface chainwheels equal to Shimano? Is there a performance difference? Thanks for any input.
I'm real satisfied with the chainwheels on the Shimano cranks I've had so far, but never owned Raceface.
