Shimano RT-CL800 Center Lock Brake Rotor w/ Magnet + Internal Teeth

Shimano RT-CL800 Brake Rotor w/ magnetic lockring for e-bikes

The Ultegra-level RT-CL800 Center Lock brake rotor is also available with a magnetic lockring with internal gear teeth for the Shimano EW-SS302 speed sensor. In this version, it is suitable for e-bikes equipped with DU-EP800, EP801 or EP600 motors and is intended for use on the rear wheel only. The brake rotor features a sandwich construction with an aluminium layer between two stainless steel layers. Thanks to Ice Technologies FREEZA, it provides excellent heat dissipation, even on steep, long descents. In addition, the design has been optimised to keep noise and weight to a minimum. The RT-CL800 can be used with both organic and sintered brake pads and is compatible with a wide range of calipers.

Technology:

Ice Tech FREEZA
Shimano Ice Technologies provide a fast heat dissipation at your disc brake. The brake pads are equipped with aluminium cooling fins. The brake rotor is constructed using a sandwich technique in which stainless steel encloses an aluminium core. The stainless steel on both flanks ensures long durability, the aluminium allows heat dissipation. FREEZA is the further development of the brake rotor, in which additional, specially coated ribs in the aluminium of the rotor ensure even better heat compensation. This cooling technology creates consistently high performance and longer brake pad durability while reducing fading and brake noise.
