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.
