Pro Cycling called the Smart Enve System 3.4 clincher wheels, "the best we've ridden". In fact, many adjectives can be aptly used to describe the SES 3.4 wheels. Some of them include: versatile, stable, smooth, snappy, solid, and fast.
The 3.4s are specifically designed as a multi-purpose wheelset that can be used in virtually all weather conditions, terrains and disciplines. The 3.4s, feature a 35mm deep front rim and a 45mm deep rear to provide maximum performance characteristics in mountainous terrain, or when the wind conditions are too strong for ultra-deep profile wheels. The 3.4 wheel system is capable of producing very low drag numbers similar to other company's 50-60mm deep wheels while creating a higher stability.
Rim widths are also wider with a 26mm wide front and 24mm wide rear. This delivers improved handling and more direct tire support. The 26mm and 24mm are optimized to work on all bike frames and brake caliper designs. The Smart ENVE System optimizes the interface between the frame surfaces and the wheels. Enve tested wheels on multiple frame designs in order to produce the maximum drag reduction. The result is a wheel system, which handles predictably, and displays superior drag results across a wide range of frame designs.
Enve optimized the shape of the rims used in the 3.4 wheelset for the most stable handling in unstable, windy conditions. The rim shapes designed to minimize the buildup of side force as the angle of crosswind changes. This allows the rider to accurately predict the handling mannerisms of the wheel and avoid dangerous over correction cycles. This focus on steering stability guarantees improved handling and confidence in varying crosswinds.
The quality of Envy rims is second to none. Envy rims feature the highest strength to weight ratio in the industry. The have proprietary molded in spoke hole technology which greatly increases the strength around each spoke hole so envy rims can handle much higher tension without spoke pull through. The wheels feature uber-reliable DT 240s hubs and light, strong DT Aerolite spokes. Black hubs, spokes, and rims deliver jaw-dropping, stealth looks. Includes skewers, rimstrips and brake pads.
I've been running this wheel set for about 5 months now and love them. Solid, fast and extremely stable in cross winds.
Pros: Strong, light and fast
Cons: Really pricy.
I have just bought a set of ENVE 3.4 wheels and i am very disappinted with them, the rim finish is just terrible, particularly inside of the rim where the tube goes. It is very bed i am worried I will be getting a lot of punctures because the surface is that rough.
Cons: very bad finish of tyre bad
