Shimano Ultegra R8170 C36 Disc Road Bike Wheels

The Shimano Ultegra R8170 C36 Disc wheels are very versatile thanks to the low carbon rim profile. But they also have good properties for climbing. A low rim ensures less rotating mass, which makes it easier to get up to speed after a turn or during a sprint. The low weight of the Shimano Ultegra R8170 C36 Disc wheelset will also make it easier and faster to ride uphill.

Driving characteristics
The Shimano Ultegra R8170 C36 Disc wheels have a playful feel to them. The low-profile carbon rims combined with the direct engagement system make them extremely responsive. This ensures a faster engagement moment of the body. Wind is actually no longer an issue thanks to a wide rim of 28mm externally, which makes a 28mm outer tyre fit perfectly. On descents they do exactly what you want them to do - turn in sharply and get going quickly after a turn.

Aerodynamics
Although the medium 36mm rims may not be that deep, there are definite advantages to the wide U-shape rims. Air resistance is significantly lower with a rim of this depth. The wind has virtually no control over them, allowing you to focus more on what is happening in front of you. Without having to make corrections. This aerodynamic gain is achieved while maintaining other properties such as stiffness, comfort and control.

Stiffness
To achieve higher stiffness, the 2:1 spoke pattern has been added to the front wheel. Thicker spokes of 1.8mm are used for more stiffness without compromising on weight. Stiffer riding characteristics are enhanced by increasing the immediate pedalling feel when accelerating. For this purpose the Direct Engagement system has been developed and added to the rear hub. And power transmission has been increased by 63% in efficiency.
