Shimano XT RT-CL800 Disc Rotor 203mm Ice-Tech Centerlock External Serration W/ Lockring

With the aim of preventing heat-induced deformation, Shimano has reinforced the alloy carrier and optimized the arm shape in the RT-CL800 brake disc. The result is not only a smoother, but also quieter braking experience. With the help of the proven Ice-Technologies Freeza design, the disc at the level of the GRX RX810 series provides first-class, consistently stable braking performance even on long and steep descents.

The key to outstanding braking performance is rapid heat dissipation, which is achieved with the help of the so-called sandwich construction (stainless steel - aluminum - stainless steel). This results in a significantly lower surface temperature, which in turn ensures less fading, a more consistent brake modulation as well as higher braking power, while at the same time less brake noise and a longer life of the brake pads.
