Shimano Dura-Ace 9000 C35 Tubular Wheelset. Looking for a versatile, lightweight wheel that can perform well in all conditions then you're search is over. The Shimano WH-9000 Dura-Ace C35 tubular wheelset is light enough for some serious climbing, sturdy enough to the cobbles, and aerodynamic enough to keep you with the group on the flats. It's a true all-around racing wheel that will put you way ahead of the competition. The C35 rims are built around a lightweight, aerodynamic 35mm deep carbon fiber tubular rim. The 35mm depth is ideal for days when you need an aero rim that will cut through the wind on the flats, but also want something lightweight for climbing--it truly is the best of both worlds. Thanks to its 24mm width, the rim corners and handles exceptionally well in a cross wind, and feels more stable even with a high wind yaw factor. The increased width also improves handling, by providing a wider contact area for the tire to be glued to, resulting in a more secure glue job and improved cornering and handling. The core of these wheels though are the all-new, redesigned Dura-Ace 9000 hubs. Shimano hubs are already legendary in their own right, and things just got even better with the 9000 11-speed version. Smooth rolling bearings, 11-speed compatibility, and a lightweight aluminum, off-set, high flange hub shell makes these wheels stiff, smooth and aerodynamic. The all-new OptBal spoke lacing system also gives these wheels a bombproof ride while reducing weight.
