Shimano RT-MT800 Center Lock 140mm Brake Rotor with Internal Gear

Ice Tech FREEZA
Ice Tech's FREEZA brake discs have even less fade due to 40°C less heat development compared to the SM-RT98. The three-layer sandwich construction consists of three stainless steel flanks and an aluminum core with integrated cooling fins. The two-part structure with the aluminum support dissipates heat well. Dirt-repellent design extends disc and pad life. What attracts the most attention is the sporty and aggressive high-tech design.
