Shimano RT-CL800 Brake Rotor

Here’s the translation:

The Shimano RT-CL800 brake rotors are high-quality components within the Shimano Ultegra R8100 and Shimano GRX groupsets. These brake rotors are specifically designed with improved heat dissipation in mind, resulting in a significant reduction of heat buildup and less risk of rotor warping. This has been achieved through an optimized material combination, allowing the rotors to perform better under heavy conditions, delivering consistent braking power and control. Additionally, the spider design is kept open to reduce the impact of wind forces, contributing to overall aerodynamics.

The Shimano RT-CL800 brake rotors come standard with an internal lockring, ensuring easy and secure installation.
