Versatility redefined.

The DURA-ACE WH-R9370 C50 is an all-round road bike wheelset optimized for lightness, stiffness, and aerodynamics at racing speeds. From the earliest design phases, testing results from world-class riders influenced the development to achieve the optimal balance between low weight, stiffness, and aerodynamic efficiency.
In addition to carbon spokes, a thoroughly revised rim construction and a new hub architecture lead to significant weight savings: at 1302 g per pair (159 g lighter than the previous model), this set enables more precise responsiveness when climbing and accelerating. This design ensures reliable stiffness at professional-level speeds and provides stable handling during sprints and in fast corners. The new rim profile offers high aerodynamic efficiency and helps maintain speed under various conditions.
