Shimano Dura-Ace 9270 C60 Disc Wheel Rear Info

The Shimano Dura-Ace 9270 C60 Disc Wheel Rear is the rear half of Shimano's deepest-profile Dura-Ace wheel, sold individually rather than only as a matched set, which lets riders replace or upgrade one wheel without buying a full pair. It's part of the wheel lineup Shimano redesigned alongside the Dura-Ace R9200 groupset, built around a 60mm carbon rim aimed squarely at flat courses, time trials, and sprint finishes rather than mixed-terrain or climbing use. At $1,415.00, it sits at the top of Shimano's disc-brake road wheel range.

The rim itself is full carbon with a D2 aero shape, 21mm internal width and 28mm external width, built to Shimano's hooked clincher/tubeless interface. Shimano pairs the rim aerodynamically with 26-30mm tires while rating it safe for anything from 25mm up to 32mm, so it covers both dedicated aero tire setups and slightly wider road tires without a compatibility problem. Shimano says the D2 shape reduces drag across yaw angles from 0 to 15 degrees compared to competing rim shapes, which covers most real-world crosswind conditions on flat, open roads.

What sets the C60 apart from Shimano's shallower Dura-Ace wheels is the rear hub and spoke design. The rear wheel uses Shimano's OPTBAL 2:1 spoke lacing, pairing 24 straight-pull, bladed spokes at 14 gauge with external alloy nipples, up from the 1.5mm spoke diameter on the previous generation to 1.8mm here. Shimano calls this its High-Rigidity, or HR, construction, and states it adds 20 percent more lateral rigidity than a standard build, with drive-side rigidity improved 63 percent over the outgoing R9100-series C40 wheel. In practice, that stiffness is meant to keep the wheel tracking true under hard cornering and out-of-saddle sprinting rather than flexing and wasting power.

The rear hub is Dura-Ace R9270-specific, built around a 12x142mm thru-axle and a Center Lock disc brake interface, with a forged and machined aluminum shell, angular contact loose-ball bearings, and a CBN-finished cup and cone — fully serviceable rather than a sealed cartridge you replace outright. The freehub is Shimano's HG12-L2 road spline, compatible only with Shimano's own 12-speed road cassettes, which matches this wheel's listed Shimano 12-speed road compatibility. The wheel ships with tubeless rim tape and valves already installed, so it's ready to set up tubeless without extra parts. Complete, the rear wheel weighs 858 grams, a number that reflects the aero-first, stiffness-first priorities of the C60 rather than a climbing-focused build.

This is a wheel for riders racing or training on flat and rolling terrain, criteriums, time trials, and triathlon courses where aerodynamic efficiency and sprint stiffness matter more than outright climbing weight. Paired with the matching front wheel or run rear-only for riders replacing a damaged wheel or building a mixed-depth setup, the C60 rear wheel gives Dura-Ace-level hub durability and disc braking in a wheel built around speed on flat roads.

The RA Perspective

The C60 rear wheel is a good option for riders who don't need to buy both wheels at once — whether that's replacing a damaged rear wheel from a crash, or building a mixed setup with a shallower front wheel for crosswind-heavy courses and this deep rear wheel for the drafting and sprint benefit.

The stiffness upgrade is real and noticeable if you're coming from an older Dura-Ace wheel or a lower-tier wheelset. Out of the saddle in a sprint, this wheel doesn't have the same flex you feel on lighter, less rigid builds, which matters most in the closing meters of a crit or a field sprint.

The tradeoff is that this isn't a wheel built for climbing days. At 858 grams for the rear alone, plus a matching front, this setup makes the most sense on flat and rolling courses, time trials, and triathlon legs where aerodynamics and stiffness outweigh rotational weight. On a hilly road race, riders will feel that weight on sustained climbs.

We'd recommend this wheel to racers and serious club riders on Shimano 12-speed drivetrains who ride mostly flat-to-rolling terrain, want Dura-Ace hub durability with disc brakes, and don't need to replace a wheel that isn't damaged just to get there.
