The lightest wheel in the Dura-Ace R9200 lineup, the WH-R9200-C36-TU rear is engineered for riders who need every gram to count without surrendering stiffness or speed. At just 684g with a 36mm full-carbon tubular rim and direct engagement hub, it delivers the snappy acceleration and immediate power transfer that climbers and criterium racers demand.

Highlights

• 684g rear weight: the absolute lightest option in the R9200 wheel family — built for KOM and QOM efforts.
• 36mm full-carbon rim: optimal balance of aerodynamic advantage and low rotational mass for mixed terrain racing.
• 28mm external rim width: accommodates modern wide tubular tyres for a more stable, larger-volume contact patch.
• 21-spoke OPTBAL pattern: 14 drive-side / 7 non-drive-side asymmetric lacing equalises spoke tension for maximum lateral stiffness under sprinting loads.
• Bladed, butted straight-pull spokes (2.0–1.8–2.0mm): stainless steel aerodynamic profile reduces drag while maintaining strength at the elbow and nipple.
• Direct engagement hub: interlocking faces eliminate the micro-delay of pawl-and-ratchet systems for instant, crisp power transfer.
• Labyrinth double-contact bearing seals: effective defence against water and contamination ingress for long bearing life.
• HG Spline freehub (road 12-speed): compatible exclusively with Shimano road 12-speed cassette sprockets.

Carbon Rim & Spoke Technology

The C36 rim strikes the ideal balance for riders who race across varied terrain — deep enough to provide aerodynamic benefit on flat and rolling roads, light enough that the rotational weight penalty on climbs remains negligible. At 36mm depth with 28mm external width, it pairs naturally with modern wide tubular tyres. The OPTBAL (Optimal Balance) spoke system deliberately places 14 spokes on the drive side and 7 on the non-drive side to equalise tension across the wheel. The result is greater lateral rigidity precisely where it is needed — during out-of-saddle efforts, sprint finishes, and hard cornering.

Direct Engagement Hub

The WH-R9200 rear hub uses interlocking direct engagement faces rather than conventional pawl-and-ratchet geometry. There is no audible ratchet delay — pressure on the pedals translates immediately into forward motion. The aluminium hub shell is finished in Shimano black with a 130mm over-lock-nut dimension and accepts a standard quick-release skewer (sold separately).

Compatibility & Fit

The WH-R9200-C36-TU rear wheel is compatible exclusively with Shimano road 12-speed cassette sprockets via its HG Spline freehub body. It uses a rim brake braking surface and is designed for tubular tyre construction. Over-lock-nut dimension is 130mm (standard road quick-release spacing). Wheel size: 700C. Not compatible with disc brake frames, 11-speed cassettes, or clincher/tubeless tyres. Quick-release skewer and wheel bag sold separately.
