The Enve SES 3.4 Clincher Disc Rim  is ready to be built into a disc-brake optimised climbing wheel with an aero advantage, ideal for road cyclists and racers who require maximum versatility for riding fast in the mountains or valleys.   Since the introduction of the original SES 3.4 in 2009, the wheel has established itself as ENVE's most versatile and consequently most popular wheelset amongst road cyclists of all abilities. This latest version of the SES 3.4 has been completely redesigned to balance speed, stability and rolling resistance to refine performance in all terrain and weather conditions.   Like the rest of the SES range, the 3.4 derives its name from its rim depths – 38mm at the front and 42mm at the rear. Each wheel features patented dissimilar SES rim geometries that favour the airflow at the front and back of the bike respectively. The wider front rim aids crosswind stability while the narrower rear rim improves overall airflow attachment for better aerodynamics.   For the SES 3.4 Disc, ENVE has completely redesigned the rim's construction and laminate. By removing the brake track and its heat management material entirely, ENVE has created a lighter rim than its rim-brake counterpart, saving weight and improving acceleration without sacrificing strength or stiffness.   The SES 3.4 also utilises advances in road tyre and frame technologies to add user-friendly tubeless compatibility optimised for 25mm tyres, giving real gains in rolling resistance, comfort, traction and reduced chance of flat tyres.   Industry leaders in carbon fibre, every ENVE rim is handmade from raw uni-directional carbon at ENVE's headquarters in Utah, USA. The bespoke construction process utilises rim-specific carbon laminates, moulded spoke holes, removable bladders, and a gorgeous paint-free finish to reduce weight while maintaining strength, stiffness and allowing the beautiful handmade quality to shine through.
