DURA-ACE WH-R9370-C99-TL Front Wheel
Cut through the wind with the DURA-ACE WH-R9370-C99-TL, a front wheel engineered to maximize aerodynamic efficiency for time trials and triathlons. A 99 mm-deep rim and an aero-focused 16-spoke carbon profile, enabled by the wheel's ultra-tall section, drastically reduce drag for elite aero efficiency at high cruising speeds.
Shaped through more than 200 million aero simulations, this is the most aerodynamic carbon rim in DURA-ACE wheel history. Super-aero carbon spokes measuring 5.2 mm wide and just 0.8 mm thick cut drag further, while Cup & Cone bearings keep the hub precise and easy to service. A 23 mm internal, hooked tubeless rim supports a 25–32C tire range for smooth pacing over TT and triathlon distances.
