Since its introduction in 2009, the Smart ENVE System 3.4 has established itself as ENVE's most versatile and consequently most popular carbon fiber aero road wheelset amongst road cyclists of all abilities. As such, it's no surprise that ENVE's first stage victory at the Tour de France was delivered by Steve Cummings aboard the SES 3.4.
The SES 3.4 is wider than its predecessor (27.5mm wide external, 21mm internal) to improve rolling resistance and improve aerodynamics for use with 25mm tires. In addition to added width, the versatile and reliable nature of the SES 3.4 has been augmented by incorporating road tubeless tire compatibility. Road tubeless compatibility means improved rolling resistance, comfort, traction, and a reduced propensity for flat tires.
Like all SES wheel models, the SES 3.4 features dissimilar rim shapes and geometries between front and back wheels to maximize aerodynamic efficiency and rideability in variable wind and weather conditions. The front rim is 38mm deep and shallower than the rear rim to aid in cross wind stability while rear rim is 42mm deep and therefore improves overall airflow attachment.
For riding in mountainous terrain where heavy braking is required, the SES 3.4 features a high temperature resistant resin system and ENVEs molded in brake track technology to ensure rim integrity and precision braking when and where it is needed most, in mountainous terrain.Technologies
The second generation SES 3.4 features the latest evolution of our patented Smart ENVE System aerodynamic rim shaping to take its performance and versatility to another level. This is a lightweight wheel for the mountains with real aerodynamic performance to boost your speed on the flat and exceptional stability. BikeRadar.com said “They sure feel fast [and] immune to the wind.”
Differentiated rim depths are fundamental to the SES range, delivering optimized aerodynamics along with incredible stability thanks to the highly developed rim profile and the shallower front rim. For the second generation of the 3.4, the depths have been revised to 38mm at the front and 42mm at the rear, with the extra benefit of a more refined aesthetic.
The external width of 27.5mm is set for optimal aerodynamic integration with a 25mm tire, allowing you to enjoy improved comfort, grip and rolling resistance without sacrificing speed. Inside the rim, the tire bed shape and width also play important roles in maximizing the performance of the tire, providing more volume which leads to even lower rolling resistance.
