The astonishing acceleration of the new DURA-ACE R9270 C36 wheelset provides an entirely new riding experience on climbs, curves, and even at red lights in traffic. Crucial to this is not only the overall weight of the wheelset but also the weight distribution of the wheel. The completely new design of the C36 saves weight wherever possible, but especially at the rim. The result is a dynamic wheelset for a fresh riding sensation. With a lighter, wider full carbon rim and a lighter hub, the DURA-ACE C36 wheelset is perfectly equipped for climbs in the mountains. The new rim, with its 36 mm high profile, offers good aerodynamic properties despite its extremely low weight. In contrast, the hub features a FREEHUB freehub body made of lightweight metal and a new engagement mechanism for increased stiffness.
