Cut through the wind.

The DURA-ACE WH R9370 C99 front wheel was developed in collaboration with professional triathletes to maximize aerodynamic efficiency during time trials and triathlons.
The 99mm high carbon rim, the aerodynamically optimized spoke profile, and the 16-spoke construction minimize air resistance and showcase their strengths, especially at high speeds.
The result is maximum aerodynamic efficiency, a more consistent pace, and support to maintain your speed consistently high over the entire distance.
