- CENTER LOCK - Disc Brake Rotor - ICE TECHNOLOGIES FREEZA - 160/140 mm

For superb stopping power in all conditions, SM-RT800 disc brake rotors deliver consistent braking performance thanks to the ICE TECHNOLOGIES FREEZA construction. With better heat management, the SM-RT800 rotors withstand brake fade on long downhill stretches and provide substantially quieter braking. SHIMANO's CENTER LOCK mounting system makes installing and removing rotors quick and easy with the spine mount and lock ring design.

    TECHNOLOGIES

    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°).
