SHIMANO's DEORE XT RT-RT800 compact and lightweight disc brake rotors feature rapid heat dissipation thanks to ICE TECHNOLOGIES FREEZA heat management system. Installing and removing the rotors is quick and easy with SHIMANO's CENTER LOCK design.

ICE TECHNOLOGIES FREEZA rotors feature an extended inner aluminum layer with wide, exposed radiator fins that boost cooling capabilities.

Shimano ICE TECHNOLOGIES FREEZA rotors offer an impressive 100°C (212°F) reduction in heat build-up compared to standard stainless-steel rotors and a 40℃ (104°F) reduction in heat buildup compared to our ICE TECHNOLOGY rotors. Our premium rotors also feature a special heat dissipation paint on the fins that can further reduce heat buildup by 10℃ (50F°).
