Shimano Centerlock Disc Brake Rotors

•Centerlock interface uses a lockring to mount the disc rotor to the hub
•Centerlock rotors are interchangeable with all Shimano disc brakes as long as the hubs and rotor size match the caliper
•Unless otherwise noted, Centerlock rotors includes lock ring and washer
•Ice Tech brake rotors (RT-98; RT-81; RT-67) feature an aluminum core clad with stainless steel braking surfaces. The innovative design sheds weight, dissipate heat and dramatically improves overall performance
•Freeza Technology (RT-99) features 3-layer structure with aluminum core and stainless steel outer layers and additional aluminum cooling fins reduces rotor surface temperature approximately 150 degrees Celsius compared to all-steel rotors
