ENVE has studied carbon-fiber long enough to know how much and what kind of material they need to put where. As such, their SES 3.4 Disc Clincher Wheelsets are lighter because the rims don't need as much material at the area once referred to as "the brake track" because that area doesn't need to resist heat build. Different rims coming out of the same shaped molds
As a result, the disc brake rims are lighter. With the 3.4's the weight savings is 35g per rim. And because of the forces that come from the hub when braking on rotors, both front and rear wheels come laced with 24-spokes in a three-cross pattern.
The rims are otherwise the same ENVE SES design, with the "3" referring to a 35mm deep, 26mm wide front rim and a 45mm deep, 24mm wide rear rim. The front is tuned for better crosswind handling and the rear tuned for greater aerodynamics and strength.
ENVE is different than their rim competition. They're a carbon-fiber company. These hoops are strong. The spoke holes haven't been cut, they've been molded, so they're stronger. The spoke nipples are inside the rim, which contributes to both the overall strength of the wheel and better aerodynamics.
The wheels are delivered with titanium-shafted ENVE skewers, rim strips, and two sets of valve extenders.
We've been discussing rims, but these are wheelsets. As such, there are two hub options. One is DT Swiss 240 Center Lock disc hubs, the other is Chris King R45 Disc hubs with six-bolt rotor mounting. Both are available for Shimano/SRAM 10/11 and Campagnolo 9/10/11 cassettes. The DT Swiss weigh 1460g for the set, while the Chris King weigh 1505g.
ENVE stands firmly behind their products. Not only do they have a five-year warranty on their products, but they also have a lifetime crash replacement policy where they'll replace any ENVE product for 50% of MSRP, provided the customer has the paperwork to prove original ownership.
