An aluminum core placed between steel braking surfaces and the alloy spider of Shimano's CenterLock SLX SM-RT68 Rotor effectively prevents heat buildup for consistent braking. Shimano's SLX SM-RT68 rotor is compatible with the CenterLock interface and comes in three sizes: 160, 180, and 203mm.

I bought these in lieu of the more expensive XTR rotors for a bike with XT brakes. They are definitely heavier and more shiny than XT or XTR rotors. Stopping power seems to be the same. And I've had no noise issues. I have no complaints but next go around I'll probably go XT or XTR just for the weight savings and better aesthetics.
does each one of these come with the required lockring?
