if anyone is using on his bike the shimano SM-RT81 rotors, i would like some suggestions and advice. I use the XT brakes with F01A resin pads and i was thinking about putting on these rotors (180/180) for better cooling and performance. Any thoughts ? I have seen the SM-RT86, too, which are a bit less expensive, but i cant understand their difference.
