Shimano DURA-ACE WH-R9370-C50-TL – a premium carbon road bike wheelset developed in collaboration with WorldTour riders and professional triathletes. Its balanced riding characteristics enable rapid acceleration, efficient climbing and stable handling when sprinting or cornering at high speeds. It is a versatile choice for road races across varied terrain and fast training sessions.

Key Features:

• 50 mm-deep rims: balanced for aerodynamics, stiffness and low weight.
• Wheelset weight: 1,302 g – the front wheel weighs 593 g and the rear wheel 709 g.
• 159 g lighter wheelset: compared with the previous-generation WH-R9270-C50 wheelset.
• Improved aerodynamics: more than 5.4 million shape simulations resulted in a 6% improvement in aerodynamic efficiency.
• Carbon spokes: reduce the overall wheel weight while maintaining the stiffness required for racing.
• Spoke count: both the front and rear wheels use 21 carbon spokes with different cross-sections.
• 23 mm internal rim width: optimised for 28–30C tyres to reduce rolling resistance and maintain a stable tyre profile.
