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 FREEZE rotor significantly reduces heat build-up in the brake system to ensure consistent high-performance braking even on the steepest downhill stretches. SHIMANO's CENTRE LOCK mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.
