Shimano RT-CL900 Center Lock Brake Rotor for Dura-Ace w/ Internal Teeth

Shimano RT-CL900 Brake Rotor - Ice-Tech FREEZA for Dura-Ace and other brakes

The RT-CL900 Center Lock brake rotor was specially developed by Shimano for the Dura-Ace BR-R9270 road bike disc brake. Apart from that, it is also compatible with numerous brake calipers from the gravel or MTB sector. The brake rotor features a sandwich construction with an aluminium layer between two stainless steel layers. Thanks to Ice Technologies FREEZA and a special heat-dissipating coating, it won't overheat even on steep, long descents. In addition, the design has been optimised to keep noise and weight to a minimum. The RT-CL900 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.
