Shimano RT-CL800 Ice Technologies Freeza Centerlock Internal Lock Ring Disc

Quieter control on any terrain

Thanks to the special focus on reducing thermal deformation of the rotor, the new disc brake rotor is quieter than ever, without sacrificing lightness or heat dissipation.

Features

• Unprecedented quietness, with superb and consistent braking performance on any long and steep descent, thanks to excellent heat dissipation.
• The new arm shape is more robust and offers quieter operation.
• Internal centerlock lockring included.

Technologies

3D Aluminum Disc Support
The 3D-shaped optimized aluminum support is specifically designed for each individual size, achieving lightness and outstanding resistance to thermal deformation.
This prevents thermal deformation across the entire disc surface and reduces rubbing noises during riding.

Ice Technologies Freeza
Ice Technologies Freeza ensures consistent braking performance with less efficiency loss, less noise, and longer pad life.

Center Lock
The Center Lock system enables simplified rotor installation with spline and lockring. The lockring mounting system reduces total work hours and installation and removal times. Additionally, the solid fixation via splines enhances precision and stiffness while increasing braking efficiency.
