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 pads lifetime as well. The basis of the construction is the discs 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.
