Your top speed is out there. Find it with the C60. The WH-R9370-C60-TL is optimized for aerodynamic performance in sprinting and sustained high-speed cruising. A 60 mm-deep rim reduces drag, improving efficiency at speed. Carbon spokes, combined with a dedicated front/rear layout and a reinforced rear wheel, deliver reliable power transfer and stable behavior under high loads. Updated rim layup and hub structure keep overall system weight appropriate, delivering the speed retention needed from the jump of a sprint through long, fast sections.

Features
Rim depth: 60 mm (Front & Rear)
Designed with 28-30C tires in mind: 23 mm internal rim width lowers rolling resistance and preserves tire stiffness
Aerodynamically optimized rim: More than 6.5 million shape simulations delivered a 9% aero improvement compared to the previous model
Carbon spokes: Carbon spoke design optimized for aerodynamic efficiency, stiffness balance in race environments
Spoke pattern — Front 21 / Rear 24: Mixed-diameter spokes and a C60-specific 24-spoke rear pattern deliver stiffness to handle high rider output
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
