Shimano Ultegra R8170 C36 Disc wheels

The Shimano Ultegra R8170-C36 Disc Carbon tubeless wheel pair adopts the same rim profile as the new Dura-Ace wheel, improving aerodynamics. Shimano takes a holistic approach to wheel design and development. Because they understand the importance of not sacrificing basic functionality when seeking quality. It not only reflects feedback from professional cyclists competing in the world's toughest races, but also incorporates the latest technology and opinions from a number of cyclists from around the world. It offers comfort and safety without sacrificing performance and is lightweight without compromising strength or durability.

Technologies:

- Center Lock: The CENTER LOCK system allows for easy installation of the disc with slot fixing and locking ring. The lock ring mounting system facilitates assembly by decreasing assembly and disassembly times. Additionally, the slot-mount safety fastener increases precision and rigidity, while improving braking efficiency.

- D2: Wind direction affects aerodynamic performance. To create the D2 rim, Shimano engineers took headwinds and crosswinds into account, with the aim of achieving optimal performance in real-world cycling conditions. Extensive prototype testing, in the wind tunnel and on the road, has shown that a wide tire with a deep tread edge performs better in a wide variety of conditions. With cornering angles between 0 and 15 degrees, the Shimano D2 rim profile reduces air resistance better than any other aerodynamic rim. This rim design also improves the lateral stiffness of the wheel and offers better vertical handling for better control, comfort and durability on the road.

- E-THRU: Tool-free thru-axle quick release system optimizes weight balance and rigidity, and allows for ease of use with a reliable internal cam mechanism. The 15mm thru-axle system has 15% higher torsional rigidity and 25% higher cross-section stiffness than a traditional 9mm quick-release front axle system.
