The ENVE Classic 65 Wheelset is choice of flatlanders and time trialists/triathletes. What may be surprising is that it's also a carbon wheelset popular with cyclocrossers and is light enough to climb with.
The 65mm rim depth can be seen from far off, but what can't be seen are the aerodynamics, weight, and strength. These, with their wide, 22mm tire beds, test fast. Because of this, time trialists love them. But the light weight, 1639g for the set, a 550g rim, make these good for criterium riders and the accelerations they must do every lap. The strength, which is hard to quantify other than to point to the EN certifications and the 'crossers who race them.
The strength is due to a long-time focus on composite construction technology. Small things like molded spoke and valve holes, and a patented, conical, interior nipple bed help keep spoke tension high, which makes the wheels both strong and durable. The strength at the rim wall is kept by smart lay up, which won't overheat under heavy braking. Thanks to both the choice of materials and rim depth, these wheels shouldn't overheat ever, as testing indicates that ENVE's carbon rim doesn't get any hotter than aluminum alloy rims.
This wheelset is high quality all the way through. The rims are laced with DT Swiss Aerolite spokes to DT Swiss 240 hubs. The rear hub has the option of Campagnolo or Shimano/SRAM cassette bodies, and they can be easily swapped at home.
ENVE packs their wheels with a bag of accessories. ENVE rim strips, brake pads, titanium-shafted skewers and valve extenders. You'll want to use everything, particularly the brake pads, as they're necessary for both maximum stopping performance and the warranty.
In a world of out-sourced production, ENVE is a bit of a rarity. Everything is built in-house. They think this is better, and stand behind their beliefs with a five-year warranty on their products, and a lifetime crash replacement policy where they'll replace any destroyed ENVE product for 50% of MSRP, provided the customer has the paperwork to prove original ownership.
