Campagnolo BORA WTO 33 Wheels. Each component of these wheels have been optimized in the wind tunnel in order to improve aerodynamic performance. The wheels features carbon rims with a unidirectional aerodynamic finish, new aerodynamic aluminum hubs, and the ceramic USB cup-and-cone bearing system: every design choice has been made with a view to optimizing performance. The profile of the rim, which has an internal diameter of 19 mm, corresponds perfectly with 23 mm, 25 mm and 28 mm tires. In addition, with the 2-Way Fit version, Campagnolo offers its tried-and-tested technology with full compatibility with clincher and tubeless tires.
