Shimano's XT Ice-Tech rotors utilize their patented Center Lock mounting system for super quick and easy mounting. These rotors use an aluminum core with steel outer plates to better control the temperature of the braking surface. This means quieter braking and, more importantly, less fade on long downhill sections and improved pad life. The various sizes give you total freedom of choice over the delicate balance of power versus weight.
The Center Lock rotor system makes it easy to install and swap out brake rotors. This system involves a splined rotor attachment and matching hub. Thanks to the reinforced inner spider ring, rotors are less prone to warp. Tighten the rotor down with a cassette lockring tool and you'll get even torque for a solid rotor attachment. If you decide to run a standard 6-bolt rotor, a lightweight adapter (sold separately) can be easily installed.
