Designed for high speeds and modern tire widths, Ultegra C60 wheels share the full carbon rim profile with Dura-Ace, but employ a hub compatible with 11 and 12s cassettes.
In Shimano Ultegra WH-R8170 C60 wheels, aerodynamics are the priority. The full carbon rim has a 21 mm internal width, compatible with tubeless, and a super-fast hub with cone and ball bearings, compatible with 12 and 11s cassettes.
