The brake discs ensure a powerful and constant braking performance
The ICE TECHNOLOGIES FREEZA brake disc ensures a significantly reduced heat build-up in the brake system. This guarantees consistently high braking power even on steep descents. With the Shimano Centerlock fastening system, the brake discs can be mounted quickly and easily thanks to the locking ring design.
Highlights
- Crisp, even braking thanks to the cooling power of ICE TECHNOLOGIES
- Better heat dissipation
- 3-layer sandwich composite made of stainless steel on the outside with an aluminum core
- Light weight

Technologies used
In this chapter we explain the technologies that the manufacturer uses for this product.
ICE-TECH
Fading, which can occur in the brake disc and pad when braking continuously on long descents, impairs braking performance. Shimano introduced ICE TECHNOLOGIES brake discs and ICE TECHNOLOGIES brake pads to create a cooling technology for consistently high braking performance. The brake disc with its 3-layer sandwich structure made of stainless steel, aluminum and stainless steel offers better heat dissipation. The brake pads also have cooling fins. The construction of the disc in connection with the cooling fins results in a longer service life of the pad, less braking noise, less fading and lower weight.
