With the release of the impressive Dura-Ace R9200-series component range Shimano also updated and redesigned their Dura-Ace and Ultegra wheelsets. In a break with their norm, Shimano is offering the first generation 12-Speed road wheels in individual (front, rear) builds, as well as by the set. This item is the Rear Wheel. For true road and allroad wheels, a new full carbon wider rim shape available was developed in three depths to modernize the line and deliver better aerodynamic overall performance while delivering superior tubeless ready capability. The rims are lighter, reducing rotational weight, and Shimano's superior hub technologies have been tapped into for their comprehensive strength, precision machining, and complete serviceability. The 360 degree Direct Engagement freehub system maximizes power transfer to create sure and immediate response from pedal input, while the superior design and build quality of the wheel overall ensures top of the class efficiency. It is important to know that these Dura-Ace wheels are equipped with a Shimano road-specific freehub body that will only work with Shimano road 12-speed cassettes. Ultegra-level wheels will have an 11-speed version which is forward compatible with 12-speed cassettes.

The shallowest version of the rim is the 36mm R9270-C36-TL, a 1350 gram wheelset optimized for climbing and descending hills or mountains. The D2 rim shape design reduces drag better than competitors at yaw angles ranging from 0 to 15 degrees. It features a 21mm internal rim width complemented by a 28mm external width that matches exceptionally well aerodynamically with 26-30mm tires, but is capable of carrying 25-32mm options safely. Braking control comes via the Shimano-developed Center Lock disc brake rotor mount that is now ubiquitous throughout road and gravel cycling. If you live in hilly or mountainous areas, love to climb and descend, this C36 is a high performing disc brake rear wheel option in a very strong, competitive class.
