The Shimano Ultegra R8170 C60 Disc wheels for disc brakes are highly aerodynamic due to their tall rim profile, offering a balanced mix of aerodynamics, stiffness, and weight for a rim height of 60mm. The rim profile, with a 28 mm external width, makes the Ultegra C60 Disc wheels less susceptible to wind compared to other wheels of the same rim height. The internal rim width allows for the mounting of 28 mm or wider tires. The spokes and spoke pattern are reinforced to enhance stiffness during acceleration, making these wheels about 9% stiffer than a Dura Ace 9170 C40 wheelset.
Ride Characteristics:
The Shimano Ultegra R8170 C60 Disc wheels offer a very direct and integrated feel with the bike. It's not immediately apparent that the wheels are actually 60 mm high, which is precisely what riders desire. They provide aerodynamic benefits without compromising ride quality. As the wind has less effect on them, the wheels become more manageable, allowing riders to concentrate more on the road ahead.
Aerodynamics:
The rim profile, with a 28 mm external width and a 21 mm internal width, perfectly accommodates 28 mm tires. A closer tire-to-rim fit reduces air resistance. The width of the U-shaped rim lessens the impact of crosswinds, hence the trend towards wider rim designs. This aerodynamic improvement is achieved while maintaining stiffness, comfort, and control. There's a significant gain of over 5 watts in air resistance compared to the Shimano Dura Ace 9170 C40 TL wheels, and an additional 1 watt compared to the Shimano Dura Ace 9170 C60 TL wheels.
Stiffness:
The Shimano Ultegra R8170 disc wheels are the stiffest in the Ultegra line, offering the most direct power transfer. This is partly due to the shorter spokes combined with the taller rim. Additionally, the rear wheel has a quick engagement of the freehub body when accelerating out of a turn or during a sprint. The power transmission efficiency has increased by about 63% compared to previous series Dura Ace wheels.
Standard Included Items:
- Shimano Ultegra R8170 C60 Disc Front Wheel
- Shimano Ultegra R8170 C60 Disc Rear Wheel
- Tubeless Valves
