ICE TECHNOLOGIES FREEZA
The Freeza technology disc brake rotor rapidly dissipates heat for more consistent braking performance under extreme conditions, offering long pad life, reduced loss of efficiency, and reduced noise. The lightweight and highly efficient three-layer sandwich construction of stainless steel/aluminum/stainless steel improves heat dissipation.

CENTER LOCK
The Center Lock system allows for simplified rotor installation with keyed connections and a snap ring. The snap ring mounting system reduces overall labor and installation and removal times. Additionally, the solid keyed connection enhances precision and rigidity while increasing braking efficiency.
