Technologies

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

CENTER LOCK This system enables easy rotor installation using a spline mount and lock ring. The lock-ring mounting system reduces total working time by shortening both installation and removal. In addition, secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
