Originally designed for the cobbles and crosswinds of Paris-Roubaix to provide an aerodynamic advantage with high-volume tires, the SES 4.5 was the first of its kind and has now been redesigned to offer more speed in a lighter package . With an internal rim width of 25mm, confident handling results, making the SES 4.5 a game-changer on technical trails with imperfect pavement. Like the rest of the SES wheel line, the SES 4.5 has been optimized for tubeless road performance and features a hookless bead design that allows for the precise rim size needed to achieve the best tubeless performance. To further enhance the reliability of tubeless tires and rims, this set of aerodynamic carbon fiber wheels features ENVE's patent-pending Wide Hookless Bead, a design element on the leading edge of the rim that provides a more forgiving surface that , in the event of an impact, will reduce the probability of pinching a tubeless tire.
