Dura-Ace C60 WH-R9370-C60-TL

The Shimano Dura-Ace C60 WH-R9370-C60-TL-R is a tubeless rear road wheel built around the demands of sprinting and sustained high-speed riding. Its 60 mm-deep rim is designed to reduce aerodynamic drag as speed increases, helping riders maintain momentum from powerful accelerations through long, fast sections. An updated rim construction works alongside a hub engineered to transmit pedalling force effectively, providing stable behaviour when the load rises.

Aerodynamic development is central to the C60 design. Shimano reports more than 6.5 million shape simulations and a 9% aerodynamic improvement over the previous generation. The rim measures 23 mm internally and 32.3 mm externally, with a profile developed particularly around 28-30C tyres. This combination aims to lower rolling resistance while preserving tyre stiffness. The hooked tubeless rim design also supports a broad range of tyre compatibility, making it a practical choice for modern road setups.

The rear wheel uses 24 carbon spokes in a C60-specific arrangement. This layout is intended to balance aerodynamic performance with the stiffness needed to handle strong rider output. At the hub, DIRECT ENGAGEMENT delivers a responsive connection between pedalling effort and forward drive. Cup-and-cone bearings can be precisely adjusted and serviced, supporting smooth operation and long-term use. Shimano lists an average weight of 759 g for this individual rear wheel, distinct from the quoted weight of a complete wheelset.

For disc-brake road bikes, the WH-R9370-C60-TL-R features a CENTER LOCK rotor interface and an E-THRU axle system with 142 mm rear spacing. The HG spline L2 freehub is designed for compatible 12-speed road cassettes, while the wheel size is 700C. Together, these details make the Dura-Ace C60 rear wheel a focused option for competitive road riding: a deep aerodynamic profile for fast efforts, carbon spokes for load management, and a hub designed to make hard accelerations count.
