With the release of the impressive Dura-Ace R9200-series component range Shimano also updated and redesigned their Dura-Ace and Ultegra wheelsets. 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 theses 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 mid-depth version of the rim is the 50mm R9270-C50-TL, a 1461 gram wheelset optimized for all-around racing and riding where more aerodynamic value is utilized. 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. Control comes the Shimano-developed Center Lock disc brake rotor mount that is now ubiquitous throughout road and gravel cycling. If you love to carry speed with efficiency and great responsiveness in group rides or races, the R9270 C50 TL Wheelset is a high performing, carbon rim, disc brake wheelset option in a very strong, competitive class.
