Ruote Shimano Ultegra R8170 C36 Disc

Ruote Shimano Ultegra R8170 C36 Disc

The Shimano Ultegra R8170-C36 Disc carbon pair for Tubeless adopts the same profile as the circle of the new dura-ace wheel, improving aerodynamics. Shimano has a holistic approach to the design and development of the wheels. Because they understand the importance of not sacrificing the basic functionality when looking for quality. Not only reflects the feedback of professional cyclists who compete in the hardest races in the world, but also incorporates the most recent technology and opinions of a number of cyclists from all over the world. It offers comfort and safety without sacrificing performance and is light without compromising resistance or durability.

Technologies:

- CENTER LOCK: The Lock Center System allows easy installation of the disk with slit fixing and locking ring. The locking ring assembly system facilitates assembly by decreasing assembly and disassembly times. In addition, the fixing of safety with cracking increases precision and rigidity, while improving braking efficiency.

- D2: The direction of the wind affects aerodynamic performance. To create the D2 circle, Shimano engineers took into consideration the opposite winds and transverse winds, with the aim of obtaining optimal performance in real cycling conditions. Large tests on prototypes, in the wind gallery and on the road, have shown that a large tire with a deep edge of the tread offers better performance in a wide variety of conditions. With corners of curve between 0 and 15 degrees, the profile of the Shimano D2 circle reduces the resistance of the air better than any other aerodynamic circle. This circle design also improves the lateral rigidity of the wheel and offers better vertical management for better control, comfort and road durability.

- E-Thru: The rapid release system of the axis passing without the need for tools optimizes the balance of weight and rigidity, and allows ease of use with a reliable internal fireplace mechanism. The 15 mm passing axis system has a torsional rigidity of 15% higher and a rigidity of the transversal section of 25% higher than a traditional system of anterior to 9 mm rapid release.
