6-Bolt Disc Brake Rotor

6-bolt Rotors Include:

• 6 bolts are interchangeable with all Shimano disc brakes as long as the hubs and rotor size match the caliper
  Ice Tech disc rotors (RT-98; RT-81; RT-67) have an aluminum core clad with stainless steel braking surfaces. The innovative design reduces weight, dissipates heat, and noticeably improves overall performance.
  Freeza technology (RT-99) features a 3-layer structure with an aluminum core and stainless steel outer layers and additional aluminum cooling fins that reduce rotor surface temperature approximately 150 degrees Celsius compared to all-steel rotors.
