Shimano's SM-RT81 brake rotors offer extremely high braking performance thanks to Ice Technology. This technology significantly reduces the temperature generated during braking, significantly reducing the risk of fading.
The SM-RT81 Brake Rotor is compatible with many MTB, Road and City disc brakes.
