TheEnve SES 4.5 AR Disc Rim is the ultimate everyday carbon fibre wheel, offering speed, comfort and traction on all road surfaces. Designed specifically for disc brake equipped bikes and large volume 28 to 30mm road tyres, the SES 4.5 AR takes an unconventional approach to bring new levels of confidence and performance to the road cycling experience. Conceptualized for the cobbles of Paris-Roubaix through ENVE's partnership with Team Dimension Data, the SES 4.5 AR Disc was developed to deliver top shelf aero performance, stability, and comfort for virtually any road surface. The ENVE SES 4.5 AR Disc is available as a tubeless clincher and tubular model rim. The SES 4.5 AR Disc borrows from ENVE M Series carbon mountain wheel tubeless technology and features hookless beads. Hookless beads improve aerodynamic performance by aiding airflow from tire to rim as well as allow for the best tubeless tire performance possible. Like all Smart ENVE System aero wheels, the front and rear rims are specifically designed for the airflow seen at the front and back of the bike. As such, the front rim is more shallow and wider to maximize stability and the rear is deeper and narrower to aid in drag reduction. In addition to dissimilar geometries, the SES 4.5 AR Disc features a disc brake specific construction that saves weight, improves strength, and creates an unprecedented ride quality. Enve SES 4.5 AR Disc Rim Features Durable enough to be used on a daily basis Evolution of their patented SES rim shape reduces drag while at the same time reducing depth Front wheel is wider and shallower to maximize cross-wind stability and handling The increase in stiffness as well as aerodynamic performance make the SES 4.5 the perfect wheelset for road and criterium racing where acceleration, and cornering are the name of the game Patented molded in spoke hole technology Molded in brake track textures
