The SES 7.8 is the fastest carbon fibre Smart ENVE System aero wheel yet which is prefect for experienced triathletes and road racers seeking maximum aero performance and stability. ENVE made the SES 7.8 to achieve two things: more speed and more stability. The SES 7.8 embodies the latest SES technologies and includes their newest molded in brake track and tubeless clincher tire compatibility. The SES 7.8 is wider and specifically optimised to perform best when used with a modern aero frame and large 25mm tires. When the race is against the wind and the clock, the SES 7.8 is optimised for the task. By reducing the tradeoffs between aerodynamics, stability, weight, and stiffness, the SES 7.8 carbon fiber aero wheel is the perfect tool for road racing and triathlon alike. The SES 7.8 features asymmetric rim geometries front to back. The front rim is 71mm deep and 29mm wide while the rear rims is 80mm deep and 27.5 mm wide. The dissimilar rim geometries improve the efficiency of the airflow in the system of bike frame and wheels. Because running 25mm tires is now standard, the SES 7.8 was designed with larger tires in mind. Additionally, frame manufacturers are now producing frames that have more clearance between wheel and frame which has opened up the design scope for a wheelset. The SES 7.8 is optimized for these frames. In addition to changes in shape and structure, the SES 7.8 features the latest molded in carbon fiber brake track texture and is compatible with road tubeless tires. The SES 7.8 when built with the ENVE Carbon Road Hub comes in at a weight of 1562 grams making it a viable choice for courses that feature flat to hilly terrain.
