Shimano RT-CL800 Ice-Tech Centerlock 140mm 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. 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.

Features
-  Quieter than ever, but with superb, consistent braking performance on any long, steep descents thanks to excellent heat dissipation
- The new arm shape is more robust, leading to quieter operation
- Ice-Tech provides consistent braking performance with less brake fade, less noise and longer pad life.
