Quiet, consistent, prolonged braking. The Shimano XT RT-CL800 Center Lock rotor is designed to reduce heat-related rotor deformation. An updated rotor arm shape and ICE TECHNOLOGIES FREEZA cooling maintain braking performance on long, steep descents without adding unnecessary weight.

ICE TECHNOLOGIES FREEZA

Radiator fins on the carrier pull heat away from the braking surface for consistent performance on long descents.

Reduced Brake Noise

Heat control limits rotor deformation for quieter braking.

Reinforced Arm Design

Updated arm shape adds stiffness and control without unnecessary weight.
