Shimano RT-CL900 Disc Rotor

Shimano's flagship disc brake rotor. Quieter than ever, but with superb, consistent braking performance on any long, steep descents thanks to excellent heat dissipation.

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.
