Jarrulevy Shimano STEPS RT-EM810 203MM CL

SHIMANO RT-EM810 disc brake rotors for speed sensor systems deliver powerful and consistent brake performance in all riding conditions. The ICE TECHNOLOGIES FREEZA 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.
