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.
- Q & A
does each one of these come with the required lockring?
- Familiarity: I've put it through the wringer
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.
