Wheels Road Disc Wheels - Carbon

In conjunction with the release of their 12-speed groupsets, Shimano also updated, redesigned, and rolled out impressive Ultegra-level wheelsets and individual wheels. 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 proven hub technologies have been tapped into for their comprehensive strength, precision machining, and complete serviceability.

The mid-depth version of the rim is the 50mm R8170-C50-TL, which when this front is paired with the rear, results in a 1570 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. Safety and control comes the simple-to-use Shimano-developed Center Lock disc brake rotor mount that is now ubiquitous throughout road and gravel cycling. This Ultegra front wheel saves you money at the hub, versus the Dura-Ace model, and while there is a weight penalty, the rotational weight is nearly the same, making this cost-effective wheel efficient, indeed.
