RT-CL800 Brake Rotors | Ice-Tech Cooling | 160mm Center Lock

The Shimano RT-CL800 is a center lock disc rotor with Ice Technology Freeza construction. These brake rotors have a three-layer clad design with an aluminum core that moves heat away from the braking surface. This gives you quieter and more dependable stopping power on long rides. Features and Benefits - Ice Technology Freeza design - An aluminum core sits between steel layers and extends into cooling fins, reducing surface heat by up to 100°C. - Clad rotor blade construction - This three-layer structure improves heat management, which helps prevent brake fade and makes brake pads last longer. - Center Lock mounting - Installs quickly and securely to compatible hubs, creating a stiff and precise connection for better braking. - Quiet and consistent performance - Better heat dissipation means less noise and a more predictable feel at the lever, even on steep descents. Applications - Equipping a road or gravel bike for long mountain descents. - Upgrading the stock rotors on a performance mountain bike. - Replacing rotors on Shimano GRX or Ultegra-equipped bikes for better braking.
