Product Description
Quieter braking for all terrains. By reducing heat-induced warping, the Shimano RT-CL900 brake rotor delivers greater efficiency and less noise without compromising on weight or heat dissipation. It's quieter than ever, yet delivers superb, consistent braking performance on all descents—long and steep—thanks to excellent heat dissipation. The arm design is more robust, resulting in quieter operation. The heat-dissipating paint further enhances braking performance.Product highlights: 3D Aluminum Bracket: The 3D-optimized aluminum bracket was developed with a specific purpose in mind for every dimension. It is lightweight and highly resistant to thermal deformation. This prevents heat-induced warping of the disc and reduces friction noise while riding. Ice Technologies Freeza: Ice Technologies Freeza technology delivers consistent braking performance with reduced fade, quieter operation, and longer-lasting brake pads.Details: Model: RT-CL900.
