Shimano SM RT800 road bike brake disc.

Shimano original parts are developed as a component of a component group. Related to component performance, they are perfectly matched to their counterparts in the component group. The optimization of component groups is automatically evident in our original parts, which is why they are always technically innovative products. The use of Shimano original parts guarantees optimum performance and top quality, ensuring reliable and safe operation of component groups for a long period of time.

Ice Technologies brake discs significantly reduce heat build-up in the brake system. This, in turn, reduces brake fade, ensuring consistently high performance even on long descents. It also extends the life of the linings and reduces the noise they generate.

Ice Technologies Freeza disc technology has produced a unique plated disc that uses aluminum zebras for improved heat control. With a larger surface area for heat dissipation, the disc reduces heat by 50°C. This, in turn, increases braking power and brake lining life by 20%.
