Shimano Dura Ace WH-R9370-C50-TL Wheelset

Be versatile. Dominate. The DURA-ACE WH-R9370-C50-TL 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.
