Want longer pad life, less noise, less fade and lighter weight? Then the Shimano XTR SM-RT99 140mm Disc Brake Rotor with Ultimate Freeza Ice Technology is for you. The clad rotor blade, which has a 3-layer sandwich structure of stainless steel, aluminum and stainless steel, incorporates aluminum fins to significantly reduce heat build-up in the brake system. This reduces fading, which ensures consistent high performance, even on long downhill stretches. It also results in a longer pad life and substantially quieter braking.

    • Increases surface area for heat dissipation
    • Rotor achieves a 50° C reduction in heat
    • 20% increase in braking force durability
