Shimano RT-EM810 Ice-Tech Freeza 203mm Centerlock Rotor M9120/M8120/M7120

SHIMANO RT-EM810 disc brake rotors for speed sensor systems provide powerful and consistent braking performance in all riding conditions. The ICE TECHNOLOGIES FREEZA rotor significantly reduces heat build-up in the brake system to deliver consistent high-performance braking even on the steepest downhills. SHIMANO’s CENTER LOCK mounting system allows the rotors to be installed and removed quickly and easily thanks to the spine mount and locking collar design.
