The all-rounder of the new Dura-Ace wheel lineup, the R9270 C50 wheelset is both lighter than the previous C40 model and nearly as aerodynamic as the previous C60. It's a wheelset at home in a wide range of conditions. From time trials to criteriums, on rolling terrain or attempting a personal best, the new C50 is the ideal wheel for spirited road riding. The perfect blend of low weight and aerodynamic performance, the all-new Dura-Ace C50 features an updated carbon tubeless rim and new hub design that drops weight while enhancing rigidity.
