Shimano CL900 XTR/Dura Ace CentreLock Rotor

Quieter control for any terrain. With a focus on decreasing disc brake rotor heat deformation, the result of the new disc brake rotor is quieter than ever brake performance without sacrificing weight or heat dissipation.

Ice-Tech FREEZA

SHIMANO’s ICE TECHNOLOGIES has realized the ultimate rotor, incorporating aluminum fins for enhanced heat control. With an increased surface area for heat dispersion, the rotor achieves a 50°C reduction in heat. This in turn generates a 20% increase in braking force durability and a 20% longer pad life.

3D Aluminum carrier​

Optimized 3D-shaped aluminum carrier is designed purposefully in every single dimension and achieves lightweight and superb heat distortion resistance. This prevents the entire rotor from deforming due to heat and reduces rubbing noise while riding.
