Shimano Ultegra/XT RT-MT800s are compact and lightweight disc brake rotors that feature rapid heat dissipation thanks to Ice Technologies FREEZA heat management system. Installation and removal is quick and easy with Shimano's centerlock design.
Shimano's Ice Tech Freeza technology means this rotor is able to cope with sustained braking and high temperatures. Shimano's advanced Freeza heat-dissipating design reduces brake fade.
External lockrings for MTB sizes install with a bottom bracket tool and fit all axles up to 20mm. Internal lockrings for Road/Gravel sizes install with a cassette tool.
