Shimano Ultegra R8170 C60 CL Front Disc Wheel

Shimano Ultegra R8170 C60 Carbon CL Front Disc Wheel

The Ultegra R8170 C60 Carbon CL Disc Wheel from Shimano features a 60mm-deep full-carbon rim that’s ideal for high-speed and flatter race events. Suited to time trial and triathlon races, this wheel is tubeless ready for fast rolling speeds, low rolling inertia and exceptional grip in all conditions. And it’s compatible with Shimano 11 and 12-Speed gear systems and it features a centre lock rotor mount for use with disc brakes.

Designed for the highest speed environments and modern tyre widths, the Ultegra C60 front wheel shares its all-carbon rim profile with Dura-Ace but employs a hub that is compatible with both 11 and 12-speed cassettes.

For situations where aerodynamics is the priority, the new Ultegra R8170 C60 front wheel features an all-carbon, 21 mm internal, tubeless compatible rim and a super-fast cup and cone bearing hub that is compatible with both 11 and 12-speed cassettes.

Centre-Lock Disc Rotor Mount

The Centre Lock system makes an easy rotor installation possible with a 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.

D2 Aerodynamic Rim Profile

Aerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, 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 tyre 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.

Shimano E-Thru Axle System

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.
