The Shimano Dura Ace R9270 C50 Road Bike Wheels for disc brakes are compatible with both tubeless and clincher tires. Shimano has made significant advancements in aerodynamics, stiffness, and power transfer. These Shimano Dura Ace R9270 C50 bike wheels feature an internal rim width of 21 mm and an external rim width of 28 mm, making them particularly suited for 28 mm or wider tires, resulting in considerable aerodynamic improvement. The 1:1 spoke pattern, combined with 1.5 mm thick spokes, enhances stiffness, while a direct engagement hub ensures quick engagement when starting.

Ride Characteristics:
The Shimano Dura Ace C50 wheels feel incredibly comfortable on your bike. Unlike other high-profile carbon wheels that often require getting used to, especially regarding stability in the wind and during descents, the Shimano Dura Ace wheels feel right immediately. You barely notice you are riding with 50 mm wheels. They respond instantly with every pedal stroke, and despite being 50mm tall, they are perfectly suitable for climbing. High-speed descents feel stable and not at all twitchy, and they corner very directly.

Aerodynamics:
The air resistance of the Shimano Dura Ace R9270 C50 has been significantly reduced, partly due to the wide rim profile with a 28 mm external width. The air resistance is considerably lower with a rim of these dimensions. Compared to the Shimano Dura Ace R9100 C40 wheels, an impressive 5.1 watts of air resistance has been saved with a lower-profile rim. Furthermore, an additional 1 watt has been saved compared to the Shimano Dura Ace R9100 C60 tubular wheel. This improvement in efficiency is achieved while maintaining stiffness, comfort, and control.

Stiffness:
To achieve higher stiffness, the 1:1 spoke pattern has been added to the front wheel. Stronger spokes of 1.5 mm thickness are used for optimal stiffness without increasing weight. Stiffer riding characteristics are further enhanced by the direct pedal feel during acceleration, achieved through the development and addition of the Direct Engagement system to the rear hub. The power transmission efficiency has consequently increased by 63%.

Weight:
Every gram counts when it comes to rotational mass. Despite the rims becoming significantly wider, Shimano's team has managed to make rims lighter than their predecessors. A set of Shimano Dura Ace R9270 C50 wheels is 161 grams lighter than the previous Shimano R9170 C40 wheels. This is immediately noticeable during acceleration, climbing, or maintaining speed with your Shimano Dura Ace wheels.

Compatibility:
Shimano has developed a special freehub body for Dura Ace 12-speed. This freehub body has more notches, reducing the rate at which the cassette wears into the body. However, it is only compatible with Shimano Dura-Ace 12-speed cassettes.

Standard Included Items:
- Shimano Dura Ace R9270 C50 Front Wheel
- Shimano Dura Ace R9270 C50 Rear Wheel
- Tubeless valves
