The family of carbon aero wheels is further enhanced with the 45 mm profile, designed to appeal to a broader customer base. The design of the rim enables maximum aerodynamic penetration, and at certain angles, the wind can actually become a valuable ally to the rider. Aerodynamic aluminium rims and hubs and ceramic USB cup-and-cone bearing system in the hubs themselves: every design choice has been made with a view to optimising performance. The 19 mm internal diameter of the rim enables tyres of 23mm, 25mm and 28mm to be fitted. In addition, with the 2-Way Fit version, Campagnolo offers its tried-and-tested technology with full compatibility with clincher and tubeless tyres. While the key purpose of these wheels is to deliver extreme performance, safety is also guaranteed by the Campagnolo AC3 (All Conditions Carbon Control) technology, which ensures safe, modular braking in all weather conditions.
