Disc brake rotor Shimano XT/Ultegra RT-MT800 140MM Ice-Tech Freeza CL Int.

The Shimano Deore XT RT-MT800 brake disc uses the successful Ice-Technologies Freeza design to decrease the temperatures while braking, resulting in consistent braking performance even in the most demanding conditions and increasing the brake pad's lifetime. 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 heat via the integrated cooling fins.
