Rebellious, unconventional, and pioneering are words that describe the one of its kind SES 4.5 AR. Conceptualized for the cobbles of Paris-Roubaix through our partnership with Team Dimension Data, the SES 4.5 AR was developed to deliver top shelf aero performance, stability, and comfort for virtually any road surface. The SES 4.5 AR 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 tyre 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 shallower 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 features a disc brake specific construction that saves weight, improves strength, and creates an unprecedented ride quality. The SES 4.5AR is also available with a Ceramicspeed bearing upgrade for the ultimate in fast-rolling speed and durability. CeramicSpeed Wheel Bearings have a proven lifetime, which is 3-5 times longer than standard wheel bearings. Our special CeramicSpeed coating delivers even lower friction and prolonged lifespan. TUBELESS FOR THE WIN Tubeless is the future and the future is now. Lower rolling resistance Flat less, ride more – Flat tires are a buzz-kill Run the Best Pressure (Visit our tire pressure page to dial in your best tire pressure) Hookless/Straight-Sidewall Design - ENVE chooses a hookless tubeless rim profile as it allows the rim’s critical tolerance at the bead seat diameter to be both consistent and accurate The ENVE SES 4.5AR is optimized for use with tubeless tires greater than 28mm wide Please refer to our Tire Compatibility page to see what tires are approved/recommended for use with the ENVE SES 4.5AR.
