The Shimano Ultegra R8170 C50 Road Bike Wheels for disc brakes offer an ideal balance of aerodynamics, stiffness, and weight. These Ultegra R8170 wheels boast aerodynamic properties comparable to the Dura Ace R9270 wheels, thanks partly to their 21 mm internal rim profile and 28 mm external rim width. This design allows for the mounting of tires ranging from 28 mm to 62 mm. The spokes and spoke pattern are reinforced, enhancing stiffness during acceleration, making these wheels about 9% stiffer than a Dura Ace 9170 C40 wheelset.
Ride Characteristics:
The Shimano Ultegra C50 wheels feel like an extension of the bike. Their aerodynamic features almost entirely negate the effects of crosswinds, maintaining speed with ease. Shimano's focus on stiffness and power transfer is evident, especially when taking corners during rapid descents, where the wheels respond instantly without feeling twitchy. The low weight of the wheels makes them highly versatile, suitable even for mountainous terrains.
Aerodynamics:
The aerodynamic qualities of the Shimano Ultegra R8170 C50 have been significantly optimized, largely due to the wide 28 mm rim profile. Air resistance has considerably less impact on rims of these dimensions. Compared to the previous series of Shimano carbon wheels, the Dura Ace R9100 C40 and C60, the R8170 C50 wheels have achieved an impressive aerodynamic advantage, saving 5.1 watts of resistance over the lower-profile rims and an additional 1 watt over the Shimano Dura Ace R9100 C60 tubular wheel. This improvement is maintained while preserving stiffness, comfort, and control.
Stiffness:
To achieve greater stiffness, thicker spokes of 1.5 mm have been used without compromising weight. The ride properties are further enhanced by a more direct pedaling feel during acceleration, achieved through an advanced freehub body system incorporated into the rear hub. The power transmission efficiency has consequently increased by 63%.
Weight:
The most noticeable weight reduction is in the outer rotating mass, namely the rims. Despite the considerable increase in rim width, Shimano's team has managed to produce lighter rims. This reduction is immediately felt during acceleration, climbing, or maintaining speed. This makes the Shimano Ultegra R8170 Disc wheels one of the most versatile on the market.
Standard Included Items:
- Shimano Ultegra R8170 C50 Front Wheel
- Shimano Ultegra R8170 C50 Rear Wheel
- Tubeless Valves
