The ENVE Classic 25 Clincher wheelset is a featherlight, shallow-dish wheelset that is tough enough for daily riding while still climbing like few clinchers on the market. The 25 refers to the 25mm depth. The rims are almost a box section in that the width is 22mm. The shallow depth means these will handle well in cross-winds, and are impressively light, at 402g per rim.
"Classic" is an unusual designation for a rim design that's only a few years old. But it's where ENVE entered the rim market and it's fairly traditional, as super-light, high-tech carbon-clinchers go. In other words, it looks like it's been around, it has been around, and it has been proven to perform like few rims on the market.
Classic elements of the rim are ENVE's design principles. The spoke and valve holes are molded rather than cut, for greater strength. They even designed a unique internal conical nipple seat for greater strength—and patented the technology. The rims utilize internal nipples because the smaller hole means greater strength which means greater spoke tension can be applied, making the rims laterally stiffer and also less likely to go out of true. The brake tracks are also molded, then finished with a slightly textured surface to improve braking power.
ENVE works with DT Swiss, which supplies Aerolite J-bend spokes, internal nipples, and 240 hubs, to keep the price down, so it's easier for you to get on these wheels.
The DT Swiss 240 hubs are known for their smooth-running bearings and fast-engaging ratchet system at the cassette body. That body is available in either Campagnolo or Shimano/SRAM 9/10/11, and is easy to service.
The wheels are built with 20 radial spokes in front and 24 two-cross spokes in back, patterns that are modern, yet fairly conservative. With the high tensions ENVE can achieve, the radial lacing has plenty of lateral strength and the two-cross is strong enough to take cyclocross abuse.
The wheels come supplied with ENVE rim strips, brake pads, titanium-shafted skewers and valve extenders. All are packed in a nifty zip bag for convenience and security.
ENVE believes strongly in their products. Not only are they a technology company, but they build their own stuff in the USA. The company is as solidly behind these wheels as these wheels are solid. They not only have a five-year warranty on their products, but they also have 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.
The ENVE Classic 25 Clincher Wheelset is a super-light everyday wheel that can be ridden every day, on-road and off.
