Some use it for cyclocross, others for time trials, but regardless, one thing can be said for certain the ENVE 1. 65 Wheelset is insanely fast. In fact, the 1. 65 is the ultralight iteration of what was already referred to as 'the founder's favorite.' So, at an even lighter, feathery 1258 grams and with a 65mm rim depth, you're gaining rigidity, speed, and aerodynamics over shallower wheels near the same weight, like the 404 Firecrest, and even within the ballpark of the Lightweight Rundkurs. It doesn't matter how dirty or far your destination is, the 1. 65 wheelset will get you there faster than the 'competition.' Of course, there are many factors to the 1. 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 1. 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 built for nothing but sheer speed. Sure, rigidity adds to this variable, but so does the build. The ENVE 1. 65s are hand built in the USA with DT Swiss 240 hubs laced with 2024 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 at the rear will ...
