Shimano RT-EM910 brake discs for speed sensor systems provide powerful and consistent braking performance in all conditions. The compact and lightweight Ice Technologies Freeza brake disc ensures a significantly reduced heat development in the braking system. This ensures a constantly high braking power even on steep descents. With the Shimano Center Lock mounting system, the brake discs can be mounted quickly and easily thanks to the circlip design. Ice Technologies ensures fast heat dissipation in combination with the Freeza brake disc design. This results in more consistent braking performance under extreme conditions, extends brake pad life and reduces brake power loss and brake noise. Lightweight disc brake pads with heat-dissipating painted protruding aluminum layer segments deliver excellent cooling performance, consistent braking power and easier operation in all conditions. The disc brake pads with aluminum/stainless steel cooling fins dissipate heat quickly. This reduces maintenance requirements, extends pad life and reduces brake force loss and brake noise.
