Shimano R9370 C50 Dura-Ace Carbon Road - Front Wheel

Be versatile. Dominate. The new Dura-Ace R9370 C50 is an all-round racing wheelset refined for lightweight performance, stiffness, and aerodynamics at RACE speeds. From the earliest design stages, testing by world-class riders informed development to pursue the optimal balance of low weight, rigidity, and aero efficiency. In addition to carbon spokes, a thoroughly revised rim layup and hub architecture deliver significant weight savings, achieving 1,302 g per pair (159 g lighter than the previous WH-R9270-C50 model) for sharper response on climbs and during acceleration. This design maintains dependable rigidity at pro-level speeds, providing stable behavior in sprints and high-speed cornering. The new rim profile delivers high aerodynamic efficiency, helping sustain speed across a broad range of conditions. Features: Rim depth: 50 mm Pair weight (approx): 1,302 g (Front: 593 g / Rear: 709 g) Designed with 28-30C tires in mind: 23 mm internal rim width lowers rolling resistance and preserves tire stiffness Aerodynamically optimized rim: Over 5.4 million shape simulations achieved a 6% aero improvement compared to the previous model Carbon spokes: Carbon spokes are optimized to balance low system weight with stiffness Spoke pattern - Front 21 / Rear 21: Combined with mixed-diameter carbon spokes to achieve low weight and stiffness for all-round use Hooked tubeless rim: Supports a broad range of tire compatibility Cup & Cone bearings: Excellent serviceability and precise adjustment deliver both speed and durability Rear wheel - DIRECT ENGAGEMENT: Superior drive stiffness for maximum power transfer
