Shimano SLX SM-RT70 disc brake rotors deliver powerful and consistent brake performance for all riding conditions. The ICE TECHNOLOGIES rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. Shimano’s center-lock mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.
