Designed for the highest speed environments and modern tire widths, the ULTEGRA C60 wheelset shares its all-carbon rim profile with DURA-ACE but employs a hub that is compatible with both 12 and 11-speed cassettes.
- For situations where aerodynamics is the priority, the ULTEGRA R8170 C60 wheelset features an all-carbon, 21 mm internal, tubeless compatible rim and a super-fast cup and cone bearing hub that is compatible with both 12 and 11-speed cassettes.
FEATURES

- Internal rim width: 21 mm
- Shared rim profile with R9200 DURA-ACE wheels
- Brake type: CENTER LOCK disc brake
- Axle fixing method: 12 mm E-THRU
- O.L.D. (mm): 100
TECHNOLOGIES
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.
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.
E-THRU
- 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. An 8 mm thru-axle system for the trekking / hybrid hub and dynamo hub and a 12 mm thru-axle system for the rear are also available.
SCIENCE OF SPEED
We take years to give you seconds. Speed was the driving force behind the new generation of road groups, and every decision our designers made was to make you faster. Shimano engineers worked to refine each component and every function to provide the best on-bike experience, whether you're sprinting to the finish on the Champs-Élysées or crushing your local climb.
