Shimano RT-CL800 Center Lock Rotor w/ Lock Ring

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.

- 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
- Disc brake rotor size: 140 mm, 160 mm, 180 mm, 203 mm

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.

ICE TECHNOLOGIES FREEZA

ICE TECHNOLOGIES FREEZA rotors utilize the 3-layer stainless steel-aluminum-stainless steel sandwich structure to reduce heat buildup. The inner aluminum layer extends inward with a wide exposed radiator fin that boosts its cooling capabilities.

CENTER LOCK

The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
