Since its introduction in 2009, the Smart ENVE System 3.4 has established itself as ENVEs most versatile and consequently most popular carbon fiber aero road wheelset amongst road cyclists of all abilities. As such, its no surprise that ENVEs 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 (29mm 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.

Tubular tires feature a rubber tread sewn onto a tube and they’re glued or taped onto specifically designed rims. Tubulars rims are significantly lighter because the reinforced walls that support a clincher tire are not necessary and the overall wheel and tire system is lighter. Tubular tires are more expensive than their clincher equivalents, harder to change because they’re glued in place and they usually go in the trash after one puncture, negatives that rule them out for most riders most of the time. However, the lower system weight makes a tubular wheelset more responsive when accelerating, climbing, cornering and braking. For this reason, tubulars remain the default choice of professional racers and also many amateurs, and that’s why ENVE is committed to offering the tubular format.
It used to be simple – train on clinchers, race on tubulars – but advances in clincher rim and tire design, plus the arrival of tubeless technology to the road, means that’s no longer the case. The best clincher and tubeless tires now out-perform top tubulars for rolling resistance. What’s more clincher rims and tires also integrate slightly more aerodynamically. For triathlon, grand fondos and nearly all road riding, tubeless/clinchers are recommended. In shorter events, or if you’re lucky enough to have a support car, committed racers will tell you that little else feels as good as a set of superlight tubs leaping out of a corner.
Need to know:
• Lighter and more responsive rims and total wheel and tire package
• Tires must be glued in place
• Recommended for criterium and road racers
• Everyone else is recommended to go tubeless
• Clincher and tubeless tires are more practical
3.4 RIM SHAPE EXPLAINED
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.
• Second generation SES rim profile
• Exceptional stability in gusty conditions
• Class leading balance of aero versus weight
• Refined depth ratio of 38mm front to 42mm rear
• Optimized width for 25mm tires
