Shimano Ultegra WH-R8170 29/28" (622 mm) Disc Brakes 12x100-12x142 Shimano HG Center Lock Pair of Wheels 36 mm Wheels

With the speed and efficiency of tubeless tires, the everyday performance of a shallow, aero profile carbon rim, and the convenience of 11 and 12-speed compatibility, the new ULTEGRA wheelset is an upgrade for any road bike. Spokes diameter (mm): 2.0-1.6-2.0 Type: ROAD Diameter: 622C Axle fixing method: 12 mm E-THRU Compatible cassette: 11/12 speed Rim height: C36 Internal rim width: 21 mm O.L.D.: 100 mm / 142 mm Technologies D2 Aerodynamic performance is affected by wind direction. To create the D2 rim, SHIMANO engineers considered both frontal and cross winds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind-tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the SHIMANO D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Center Lock The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. E-Thru Axle The tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15 % stiffer torsionally and 25 % stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-THRU axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.
