SHIMANO RT-CL800 SS 140MM INT SERRATION

Quieter control for any terrain. With a focus on decreasing disc brake rotor heat deformation, the result of the Shimano RT-CL800 disc brake rotor is quieter than ever brake performance without sacrificing weight or heat dissipation. Quieter than ever, but with superb, consistent braking performance on any long, steep descents thanks to excellent heat dissipation. The arm shape is more robust, leading to quieter operation.
