The Shimano RT-CL900 Ice Tech Freeza Disc Brake Rotor significantly reduces heat deformation while delivering quieter, more consistent braking performance for road cycling and gravel adventure riding.

Whether you’re spending the weekend exploring your favourite countryside gravel routes or simply taking the long road home across mixed terrains, this hydraulic disc rotor is specifically dedicated to gravel adventure riding. Featuring the revolutionary Ice Technologies Freeza three-layer rotor construction with stainless steel on the outer surface and aluminium on the inside, it delivers superior braking performance, while keeping its overall weight reduced to a minimum.

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.
