Shimano WH-RS710 C32 Disc Clincher 700c Front Wheel

High performance carbon road racing disc brake wheel meets the demands of today's professional and amateur riders.

Shimano has brought full carbon wheels to a new level. With a development concept shared with Dura-Ace and Ultegra, the new full carbon wheels offer balanced performance at a lower price. The C32, with its focus on acceleration and climbing, shares DNA with the C36 Dura-Ace and Ultegra wheel options.

Technology

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.

Compared to the conventional product C40-TL, air resistance has been reduced at all yaw angles on C36-TL, which has about the same rim height. In the conversion method that considers the direction of the winds received under actual running conditions, the drag has been reduced by about 3 W. Of course, air resistance has been further reduced on both C50-TL and C60-HR-TL.

Science of Speed

Wheel performance is determined by three factors: aerodynamics, rigidity, and weight.

The new Shimano Road wheel collection optimizes the balance of those characteristics based on specific applications like climbing, all-round performance, or high-speed scenarios. Wheels unlike any other.

Decomposition of acceleration performance

To develop a wheel that advances crisply, responding to the rider’s pedalling force, that is, a wheel with excellent acceleration performance, Shimano made efforts to achieve two elements: improvement of drive rigidity and reduction of energy required for acceleration.

Drive rigidity

Shimano succeeded in dramatically increasing the drive rigidity compared to that of a conventional model.

Compared to the conventional product C40-TL, the drive rigidity has improved by 63% on C36-TL, by 69% on C50-TL, and surprisingly by 89% on C60-HR-TL (high-rigidity specification).

Decrease of energy required for acceleration

Compared to the conventional product C40-TL, the energy required for acceleration has been reduced by 12% on C36-TL, by 10% on C50-TL, and by 6% on C60-HR-TL.

Centre Lock

The Centre 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.
