Shimano RT-CL800 Ice Technologies Freeza Centerlock disc brake rotor (External Lock ring)

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

• Quieter than ever, but with superb and consistent braking performance on any long, steep descent, thanks to excellent heat dissipation.
• The new arm shape is more robust and offers quieter operation.

Technical specifications

• Model: RT-CL800
• Series: GRX 11-speed
• Center Lock
• Ice Technologies
• Ice Technologies Freeza

Technologies

3D aluminium disc carrier
The optimised aluminium support with 3D contour is specifically designed for each individual dimension and provides light weight and outstanding resistance to thermal deformation.
This prevents thermal deformations over the entire disc surface and reduces friction noise when running.

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 makes simplified rotor installation possible with key and stop ring couplings. The stop ring mounting system reduces total working hours and installation and uninstallation time. In addition, the solid fixing by means of key clutches enhances precision and rigidity while increasing braking efficiency.
