Shimano RT CL800 Centerlock brake disc

The new Shimano Ultegra RT-CL800 Ice Tech Centerlock brake discs with additional cooling fins for even better cooling.

Smoother control on any terrain. Quieter than ever before, yet with first-class and reliable braking performance on all long, steep descents thanks to excellent heat dissipation. When developing the new brake disc, the aim was to prevent heat-induced warping. The result is incredibly quiet braking performance without compromising on weight or heat dissipation.

Shimano RT CL800 Ice Tech Freeza Brake Disc Technical Specifications:

• Ice Technologies: Cooling technology for consistent performance
• Sandwich composite with stainless steel outer layer and aluminium core
• Two-piece construction for greater stiffness and lower weight
• Self-cleaning design
• Heat-resistant, reduced fading, low-noise
• Disc diameter 140 mm
• Weight: Disc 96 grams (manufacturer’s specification)
• Compatible with all Shimano hydraulic road and gravel disc brakes
• Includes lockring with internal screw thread

Internal spline lockring – internal tool holder: 23 mm inner diameter with 12-tooth spline, compatible tools e.g. Shimano TLLR15, Pedro’s 6460000. Corresponds to the tool used for cassette installation

Shimano Ice Technologies:

combined with the FREEZA brake disc construction, ensures rapid heat dissipation. This results in more consistent braking performance under extreme conditions, extends the service life of the brake pads and reduces loss of braking power and brake noise. The aluminium core is encased by the steel braking surface. This reduces heat build-up by a good 25 per cent and increases the stability of Shimano MTB disc brakes. The redesigned Ice Tech Freeza brake discs at Deore, GRX and Ultegra levels, RT-CL800, have been engineered to ensure maximum heat dissipation, resulting in more consistent braking performance and longer pad life.
