The Shimano Deore XT RT-MT800 brake disc uses the successful Ice-Technologies Freeza design to decrease the temperatures while braking what results in a consistent braking performance even in the most demanding conditions and increases the brake pad’s lifetime as well. The basis of the construction is the disc’s so called sandwich structure (stainless steel – aluminium – stainless steel) which not only improves braking power and reliability, but also effectively dissipates the heat via the integrated cooling fins.
The design of the Shimano XT / Ultegra / GRX RT-MT800 disc brake rotors is a further development of the successful ICE TECHNOLOGIES FREEZA design.
