I've got a Campag Centaur 10spd Ultra Torque chainset, 170mm carbon cranks, 50/34 rings. The existing rings are ok but worn (no idea how many miles but they weren't slipping). I did buy a new set of TA rings to go on them. The cranks are not scratched or scuffed. The inside of the LH crank does have an adhesive deposit from where I stuck the cadence sensor onto it. Otherwise in excellent condition.
PM me if you're interested.
