Shimano RTMT800 Centerlock brake disc

The Shimano XT RT-MT800 Ice Tech Centerlock brake discs on the 4- or 5-star aluminium carrier are manufactured using a sandwich construction. The aluminium core is encased by the steel braking surface. This reduces heat build-up by a good 25 per cent and increases the durability of the Shimano MTB disc brakes. The redesigned Ice Tech Freeza brake discs at Deore XT level, RT-MT800, have been engineered to ensure maximum heat dissipation, resulting in more consistent braking performance and longer pad life.
