Shimano XT SM-RT76 6-Bolt disc rotor is available in either 160mm or 180mm sizes and offers great braking response thanks to a heat-dissipating design.
2-piece construction consists of a durable brake track made of steel while a lightweight aluminum spider helps dissipate heat and add rigidity
Lower rotor temperature means less power fade and improved brake pad longevity
The Shimano XT SM-RT76 6-Bolt disc rotor is sold as an individual rotor (with mounting bolts and plates); not compatible with Center Lock hubs
