The ENVE Smart System 3.4 Disc Clincher is part of the SES series. ENVE used its most sophisticated technology and engineering techniques to create this fast, stiff, and aerodynamic wheelset. The 3.4's aerodynamic design starts with the size differential of the wheels. ENVE accounted for the different behaviours of front and rear wheels, and designed the 3.4s with the front wheel that's 35mm deep and 26mm wide, while the rear wheel is 45mm deep and 24mm wide. The front wheel's shallow profile and wide stance helps decrease drag in windy conditions. On the other hand, the rear wheel's depth decreases drag due to greater stability. According to ENVE, the 3.4s create a low drag number rivalling many competitors' 50mm and 60mm depth wheels.
One of the most noticeable advantages of the 3.4 carbon clincher wheelset is its enhanced stability. The 3.4 demonstrates stellar results under the ENVE Stability Index, a series of tests that incorporates the measurement of transient aerodynamics. The test represents real-world conditions, and ENVE is one of the only non-Formula One manufacturers to conduct it. The 3.4 shape that was developed as a result of these tests ensures predictable airflow attachment over the rim, regardless of crosswind; In a crosswind, the 3.4 experiences a build-up of side-force equal to the changing angle of the wind, and the predictability prevents the need for rider over-correction.
The Smart System 3.4 Disc Clincher is also light, stiff, and strong. The ENVE SES series boasts the highest strength-to-weight ratio on the market, and it's due in part to ENVE's patented process of moulding in spoke holes, nipple seats, and valve stem holes. Knowing that carbon fibre gains strength from continuous fibres, ENVE routes the fibres around each hole in a 100% intact design. This design allows a lower weight at the spoke face, and adds overall rigidity to the rim. ENVE also removes the rim-shaping inflatable bladder in the rim. This time-consuming process reduces rim weight and makes for a perfectly tensioned wheel build.
Additionally, the strength of the wheel is perfectly suited for disc brakes, making these an ideal cyclocross or gravel road race wheelset. By pairing Smart ENVE System aerodynamics and ENVE mountain rim technologies, ENVE have created a disc specific road wheelset that reduces weight, and improves strength over the standard rim brake SES 3.4 models. These attributes mean that the fun doesn’t have to stop when the pavement ends.
