As an all-rounder in the new DURA-ACE wheel line-up, the C50 is lighter than its predecessor, the C40, and almost as aerodynamic as the previous C60. This wheel feels at home in a wide range of conditions. Whether time trials or criteriums, hilly terrain or attacking your own personal best time, the new C50 is the ideal wheel for ambitious road cyclists.
The brand new DURA-ACE C50 wheels impress with the optimum combination of low weight and aerodynamic performance, with the revised full carbon tubeless rims in particular offering high stiffness and reduced weight at the same time.
