The Shimano Dura-Ace 9270 C50 Disc Wheelset is for the spirited rider who wants to do it all on the road. This lightweight and aerodynamic wheelset is lighter in weight than the C40 and rivals the aerodynamic efficiency of the C60. This makes it a confident choice for nearly any type of road riding from time trials to criteriums or personal best times on the road. An updated carbon tubeless rim and new hub design simultaneously drops weight and increases stiffness. Please note that these wheels are only compatible with Shimano 12-speed cassette sprockets. The Shimano Dura-Ace 9270 C50 Disc is your new all-around road wheelset.
