The WH-R9370 C99 and its matching Disc rear make up Shimano's dedicated aerodynamic race set-up in the new Dura-Ace range, built for time trial, triathlon and solo efforts against the clock. Run the 99 mm C99 front wheel with the full-carbon Disc rear and you have the fastest configuration in the line-up for when every watt of drag counts.
The C99 front runs super-aero carbon spokes (5.2 x 0.8 mm) and a 99 mm full-carbon rim (23 mm internal / 35.2 mm external) to minimise drag in sustained high-speed efforts, while the rear is a full-carbon disc engineered for maximum aerodynamic efficiency and rigidity. Both use a Center Lock rotor mount and the brand's adjustable cup-and-cone hubs, with the rear built around a direct-engagement 12-speed HG Spline L2 freehub. Tubeless-ready and optimised for 28-30C tyres. Front and rear wheels are sold individually.
