The pinnacle in stopping power

DURA-ACE SM-RT900 disc brake rotors deliver consistent braking performance for better control and confidence in race conditions. The ICE TECHNOLOGIES FREEZA rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. SHIMANO's CENTER LOCK mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.
