Shimano Dura-Ace 9000 C35 Clincher Wheelset
Shimano's Dura-Ace 9000 C35 wheelset epitomizes the illustrious reputation of the Dura-Ace title. With the C35, the weight of the wheels is centered at the hubs. This means that the rim weight is reduced, and thus the rotational weight is decreased. New to Dura-Ace 9000, the wheels receive Shimano's OptBal 2:1 lacing pattern. In typical Shimano fashion, this system engineers off of the obvious, yet previously unchallenged, physics of wheel stress. Coupled with the aerodynamic 35mm rim depth, you have a wheelset that gets up to speed faster, and requires less rider effort to pin it and hold it. The centering is made possible by a clever Shimano design that's principled in the use of Shimano's angular contact bearings.
