I've had these chainrings on Dura Ace 7410 cranks (8-speed) and the front shifting is not good. Due to them being made primary for 10-speed systems the distance from outer to inner chainring is too small for 8-speed systems. This leads to the chain rubbing on the big ring when you are on the small ring someway down the casette. It also makes it almost impossible to shift the chain back on if it derails in front. (it also derails easier)
