While maintaining all of the performance and durability characteristics there were incorporated the same improvements like on the Shamal Ultra wheels before. The goal was an even more efficient and performance-oriented rim, completely redesigned with inspiration from the growing trend that sees the use of increasingly wider tires. With this popularity of both 25 and 28 mm tires the wheel needs to be designed in a way to optimize the tire / wheel interface which is proved to be more aerodynamic compared to the same size tires mated to a C15 rim.

The new wider C17 rim ensures a more efficient shape of the tire, improving cornering grip and safety while reducing aerodynamic drag and rolling resistance. A seemingly small increase in width offers a surprisingly different riding experience. The structural optimization ensures furthermore a surefooted grip on clincher tires as well as a better braking feel.
