TECHNOLOGIES

ICE TECHNOLOGIES FREEZA – combined with FREEZA disc brake rotor construction rapidly dissipates heat for more consistent braking performance in extreme conditions, longer pad life, and less brake fade and noise. The lightweight and highly efficient three-layer sandwich structure of stainless steel–aluminum–stainless steel enhances heat dissipation.

CENTER LOCK – system makes an easy rotor installation possible with 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.
