Shimano RT-CL800 Center Lock Brake Rotor for Ultegra w/ Internal Teeth - silver-black/160 mm

Shimano RT-CL800 Brake Rotor - Ice-Tech FREEZA for Ultegra and other brakes<\/h2>
Shimano has developed the RT-CL800 Center Lock brake rotor especially for the Ultegra BR-R8170 road bike disc brake. It is also very suitable for the GRX Gravel brakes. Apart from that, it is also compatible with numerous brake calipers from the MTB sector. 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 comes with a lockring with internal gear teeth, and can be used with both organic and sintered brake pads.

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.
