The DURA-ACE Rear Disc Wheel minimises drag in time trials and triathlons, helping maintain speed over long distances.
A full disc construction and highly optimised aerodynamic profile work together to maximise efficiency when every watt matters.
Refined Race Performance
DURA-ACE wheels set the bar for race-level efficiency, combining lightweight design with precise handling at speed.
Erase the Air
The full disc construction is engineered to minimize aerodynamic drag and maximize efficiency at speed. Designed for time trials and triathlons, it helps riders maintain momentum and conserve energy over long race efforts.
Optimised as a System
When paired with the DURA-ACE C99 front wheel, the Rear Disc completes SHIMANO's most aerodynamic wheel system. Together, they deliver the efficiency and speed retention needed for time trials and triathlon racing.
