The ENVE M90 Ten 27. 5in Wheelset is the replacement for the World Cup DH proven DH series, and it's certainly worthy of the distinction. Taking lessons learned from ENVE's World Cup DH program, the M90 Ten is a marked improvement over its predecessor, with significant improvements being made in both rim profile and impact resistance. With a generous internal width, and an even stronger redesigned profile, this wheelset is built to take you to the top step of the podium, and to many seasons' worth of grins in between races. ENVE had a tall order ahead of it when designing a successor to the World Cup DH proven DH rim, but unsurprisingly, the team in Ogden delivered in spades. The 27. 5in M90 Ten rim now weighs 509g, saving roughly 15g over the previous 27. 5 DH rim, but the real payoff is increased width and astounding strength. Part of the strength increase comes from trading in traditional bead hooks for a redesigned beadless hook bead, which is both lighter and more impact resistant. The width is a whopping 25mm internally, which provides a round tire profile, for greater cornering stability, and more rubber on the ground at any given time. Anyone who's familiar with ENVE knows the fanatical lengths that its engineers go to in order to achieve a perfect ride feel. Accordingly, the M90 Ten has been tuned to provide a degree of vertical compliance, enhancing both grip and rider comfort, without sacrificing the fantastic lateral rigidity that endows ENVE with the on rails feeling for which they're prized. The rim tells most of the story, but these wheels are hand built in Utah, to exacting standards, which provides the longevity you'd expect out of a class leading wheel system. They're laced to DT Swiss 240 hubs, with a standard 6 bolt rotor interface. The 240s have become a staple for their lightweight construction, remarkable durability, and tool free service, which makes them a perfect match for the M90 Ten.
