Technologies

Ice Technologies Freeza​
Ice Technologies Freeza provides consistent braking performance with less brake fade, less noise and longer pad life.

Stay Cool. Keep Quiet. Stop Faster.
Ice Technologies Freeza rotors deliver next-level braking performance, surpassing our already exceptional ICE TECHNOLOGIES rotors. Their heat-dissipating radiator fins help keep things cooler in extreme conditions to provide stable stopping power with less brake fade and noise.

3D Aluminum carrier​
An optimized 3D-shaped aluminium carrier is designed purposefully in every single dimension and achieves lightweight and superb heat distortion resistance.
This prevents the entire rotor from deforming due to heat and reduces rubbing noise while riding.

Center Lock
The CENTER 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 for both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
