Shimano CL800 Ice Tech Freeza Disc Brake Rotor Disc Brake Rotors
  • £54.99

Fully equipped for your next gravel bike adventure across mixed terrain conditions, this hydraulic disc brake rotor is kitted out with a tough build and performance-enhancing technologies to conquer every ride. Focusing on decreasing disc brake rotor heat deformation, this model features Shimano's renowned Ice Technologies Freeza construction that delivers maximum stopping power without sacrificing weight or heat dissipation. Another highlight is it's quieter than ever thanks to its more robust alloy carrier and optimised arm shape, which reduces heat deformation of the rotor during hard braking. This leads to more consistent braking and quieter operation from this rotor, so you can focus on the road and the descent ahead.  Proprietary 3-Layer Construction An extra layer of heat protection, Ice Technologies Freeza rotor construction uses a proprietary three-layer sandwich design with an exposed radiator fin. Together with the heat-dissipating paint, Freeza rotors deliver supercooling forces for even more reliable braking performance and lighter operation under all conditions. Ice Technologies Freeza rotors provide consistent braking performance with longer pad life, less brake fade and noise. Centre Lock System The Centre Lock System makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.   Manufacturer's Part Numbers: RTCL800SI Black 160mm RTCL800SSI Black 140mm
