ICE TECHNOLOGIES FREEZA rotors utilize the 3-layer stainless steel-aluminum-stainless steel sandwich structure to reduce heat buildup. The inner aluminum layer extends inward with a wide exposed radiator fin that boosts its cooling capabilities.
Aluminum radiator fins boost cooling capabilities to enhance braking performance
ICE TECHNOLOGIES FREEZA rotors feature an extended inner aluminum layer with wide, exposed radiator fins that boost cooling capabilities.
Shimano ICE TECHNOLOGIES FREEZA rotors offer an impressive 100°C (212°F) reduction in heat build-up compared to standard stainless-steel rotors and a 40℃ (104°F) reduction in heat buildup compared to our ICE TECHNOLOGY rotors. Our premium rotors also feature a special heat dissipation paint on the fins that can further reduce heat buildup by 10℃ (50F°).

The 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.
