There was a time when a carbon wheelset it meant that you were stuck with carbon tubulars. And while we admit that tubulars are the gold standard for racing, for rides or races without sag or neutral wheel support, they aren't too practical. Turning the tubular trend around, the Enve Classic 25 Carbon Clincher Wheelset has been specifically designed to provide the best qualities of carbon rims. Yes, they're light, they're fast, and they provide all of the practical benefits of clinchers. So, whether you're racing road or cyclocross, you're going to benefit from the carbon genius that is Enve.
Of course, there are many factors to the 25's ridiculous stiffness-to-weight ratio. Starting at the interface between the spokes and the rim, Enve uses a patented process of molding in spoke holes, nipple seats, and valve stem holes. Knowing that carbon fiber gains strength from continuous fibers, Enve routes the fibers 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. When built, the molded design promotes both higher spoke tension and tension uniformity. Another aspect of the 25's light weight is due to Enve's use of removal bladders during the molding process. While most composite rim manufacturers leave the rim-shaping inflatable bladder in the rim, Enve spends the time and money to remove it. This time-consuming process reduces rim weight, and makes for a perfectly tensioned wheel build. Guaranteeing this, Enve has received a grant from the state of Utah, and it tests its rims on a state-of-the-art test fixture designed in conjunction with the Utah Center for Aeronautical Innovation. So yes, it is rocket science.
And while all of this technology creates an aggressive stiffness-to-weight ratio, we all know that a 25mm deep wheel is solely built for rugged speed. Sure, rigidity adds to this variable, but so does the build. The Enve 25s are hand-built in the USA with DT Swiss 240 hubs laced with 20/24 DT Swiss Aerolite bladed spokes. So, when you utilize the quick, powering gains of the rim, the 240's low-resistance and minimal rotational weight will keep your speed on the rivet with less exertion coming from your end.
The Enve Classic 25 Clincher Wheelset is available in a clincher version. For the freehub body, you're able to choose either a Campagnolo or Shimano compatibility — both are 11-speed compatible. Please note that these wheels weigh around 1376 grams per pair, and that they feature a maximum tire pressure of 125PSI.
