ROSE Bikes Dura-Ace RT-CL900 Brake Disc incl. Lockring (externally splined)| Accessories

Super-silent and extremely robust: When developing the RT-CL900 disc rotor, SHIMANO paid even more attention to optimal heat dissipation. The goal: Prevent heat-related deformation for even quieter braking – without compromising on weight, stopping power and stability.

For this purpose, the design of the spider was specially adapted, resulting in a more stable construction overall. The proven ICE TECH FREEZA technology also ensures first-class heat management at the friction ring. The ring’s sandwich construction with an aluminium core between two stainless steel layers effectively dissipates heat via the integrated cooling fins with additional thermal coating – for increased resistance against fading and improved braking performance. You can therefore rely on the reliable braking performance of the RT-CL900 brake disc even on long, steep descents in all conditions.
