Cyclocross-specific tire bed shape, ultra-low weight, softer ride, disc-only
High-end carbon tubular wheels for cyclocross racing have historically been little more than little more than repurposed road items (not unlike the sport of cyclocross itself, in fact). The new Enve CX wheels, however, are fully purpose-built for the task with a rim shape designed specifically around high-volume tubulars.
According to Enve, three factors make its new wheelset ideal for cyclocross.
The tire bed on the new Enve CX wheels is perfectly matched to 33mm-wide cyclocross tubulars
First, the shape of the tire bed has a larger radius than what would typically be found on a wheel primarily designed for road use. At least in theory, this equates to better contact between a 33mm-wide tubular ’cross tire and the rim for a stronger and more consistent bond that’s also easier to glue.
Second, Enve says the lay-up for the new rims has been tweaked for a softer ride on rough terrain. As compared to a wheel that’s stiffer radially, this should not only make the new Enve CX more comfortable for the rider but also potentially deliver improved traction.
Finally, the Enve CX rim profile also features corners that are more bluntly shaped than the company’s more road-oriented wheels. Although pinch flats are rare with tubulars, they’re not unheard of – and Enve claims this modification will lessen those chances even further.
The rim measures 28mm wide (external measurement) and the edges are blunted to reduce the chance of pinch flats
While the ride quality and flat resistance claims may come across to some as suspect, the larger-radius tire bed is fantastic in this application – and long overdue for a sport that continues to grow.
Regardless, Enve’s new CX wheelset is shockingly light with an actual weight of just 1,269g (583g front, 686g rear) with a Shimano-compatible freehub body and thru-axle end caps throughout. Keep in mind, too, that that’s with light – but not exotically so – DT Swiss 240s hubs. Riders who want to go even lighter can instead choose DT Swiss 180 hubs while those who want a quicker engagement can opt for speedy Chris Kings.
Enve will offer the new CX wheels built around DT Swiss or Chris King hubs, or as standalone rims
Claimed weight for the rims alone is 285g apiece.
