C36 – For Fast Accelerations and Climbing Delivering the lowest rotational weight and quick acceleration, Shimano’s C36 rim depth is for riders who live for ultimate responsiveness for punchy attacks on the flats, steep ramps on killer climbs, or snappy sprints at the finish line. 

C50/C46 – Perfect Mix of Aerodynamics and Weight For riders seeking the perfect blend of flat-out speed and climbing capability, the C50 and C46 wheels are the ultimate all-around rim depth, ready to tackle any terrain, any pace, and any wind direction. 

C60 – The Ultimate Aerodynamic Advantage Whether you’re a breakaway specialist, zeroed in on time trials, or planning a long solo attack off the front, the C60 is tailor-made to maximize efficiency and slip through the wind while providing maximum lateral rigidity for the most powerful sprints.

Rim Material

Carbon – Shimano premium carbon road wheels deliver the best blend of lightweight strength, aerodynamic rim shape, and lateral stiffness. This is achieved through precision-engineered design, layups, and resin formulas. All new wheelsets for 9200, 8100, and non-series RS710 wheels feature this technology, but each tier differs in the material, layup, resin, and finishing.

Freehubs

12-Speed Only – In the pursuit of ultimate performance, Shimano designed the 9200 Dura-Ace freehub with all-new Hyperglide L2 technology for maximum power transfer and minimum weight. The freehub features lightweight aluminum construction with a new spline design to prevent excessive gouging from the cassette over time. Due to this new construction and spline design, Dura-Ace wheels are only compatible with 12-speed road cassettes and drivetrains.
