Details

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. The new 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 and is available in both rim and disc brake models. 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 models, the SES 3.4 features dissimilar rim shapes and geometries between front and back wheels to maximize aerodynamic efficiency and rideability in variable weather conditions. The front rim is 38mm deep and shallower than the rear rim to aid in cross wind stability while the rear rim is 42mm deep and therefore improves overall airflow attachment.

DISC BRAKE CONSTRUCTION
At ENVE, we do a lot more than just slap decals over the brake track and lace the same rim to a disc hub. Drawing on our expertise gained developing the world’s best mountain bike wheels, our disc-specific road rims are fully optimized for the format. Freed from the constraints of a heat-proof carbon braking surface, the optimal construction of a road wheel can be reconsidered. The result is a rim that is even lighter, stronger and faster than our standard-setting, group test-winning rim brake wheels.

Carbon brake tracks dictate a lot of rim design. By taking them away and re-engineering the rim we have improved the lateral stiffness, the impact resistance and the weight by 40-60g per rim. While disc hubs mean that total wheelset weights will remain near identical between rim and disc brake wheelsets, the disc brake wheelset will feel more responsive in acceleration, steering and braking because the mass has been shifted from the rim (higher rotational inertia) to the hub (lower rotational inertia).

Need to know:

• Disc-specific construction with no brake tracks
• Rims are lighter by 40-60g per rim
• Impact resistance increased
• Greater lateral stiffness
