The Enve 65 wheelset has been touted as the 'Founder's Favorite' of all the rims in the Enve arsenal. Enve's most versatile rim, the 65 is the preferred rim for professionals for everything from cyclocross to triathlon to road racing. There's even a peloton debate on whether they're better at climbing or time trials. Seriously, though. The funny thing is that pros all say that it?s the best rim for whatever discipline they've been using it for. With a 65mm rim depth, the wheel offers weight savings comparable to many top wheelsets like the HED Stinger 4 Carbon Tubular and the Zipp 404 Firecrest Tubular. We are talking about a 65mm deep clincher, right?Of course, there are many factors to the 65'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 65'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.And while all of that technology creates an aggressive stiffness-to-weight ratio, we all know that a 65mm deep wheel is solely built for speed. Sure, rigidity adds to this variable, but so does the build. The Enve 65 is hand-built in the USA with DT Swiss 240s laced with 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 (around 209g) will keep your speed on the rivet with less exertion coming from your end. And when using a 65 as a rear wheel with an Enve 45 up front, your aerodynamic footprint gets into disc wheel categories.The Enve 65 wheelset is available as a rear wheel and in a clincher version. For the freehub body, you can choose either a Campagnolo or Shimano compatibility. Please note that the Shimano option is compatible with the new Shimano Dura Ace 9000 11-speed system.
