ICE TECHNOLOGIES FREEZA
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.
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.
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°).
Available in resin or metal compound, the optional radiation fin pad with a 2-layer back plate (aluminum fin with stainless steel) further improves radiation performance.
