The lightweight midweight heavyweight.
While the 29-inch wheelsize has largely dominated the cross-country mountain bike scene in recent years, riders are starting to discover the advantages of a smaller, lighter, more nimble wheel as the 27.5-inch wheel size gains in popularity, including some cross-country riders. ENVE has noticed, too, which is why it developed the ENVE M50/Fifty 27.5-inch Wheelset, quite possibly the best cross-country-oriented 27.5-inch wheelset in the game right now.
When ENVE set about redesigning the replacement for its featherweight "XC" rim, the design parameters were clear — make them lighter, wider, and smoother riding. And unsurprisingly, the team in Ogden, Utah, delivered in spades. The 27.5 M50/Fifty rim was is the result, now weighing a paltry 330g, shaving a full 50g per rim as compared to the XC. Part of this weight savings has been accomplished by trading in traditional bead hooks for a redesigned beadless hook bead, which is both lighter and more impact resistant. The width has grown to 21mm internally, which is an increase of 3mm. That translates into a rounder tire profile, for greater cornering stability, and more rubber on the ground at any given time. By relieving material from the rim, ENVE has taken the M50/Fifty’s tuned ride feel to previously unseen levels. 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 M50/Fifty has been tuned for greater vertical compliance, thereby reducing rider fatigue, 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 there's more to it, too. The 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 your choice of either a Centerlock or standard 6-bolt rotor interface. Additionally, you can choose between a standard freehub or an XD driver, for use with SRAM’s one-by-eleven drivetrains. The 240s have become a staple for their lightweight construction, remarkable durability, and tool-free service, which makes them a perfect match for an ENVE wheelset.
The ENVE M50/Fifty 27.5-inch Wheelset is available with either an XD or standard freehub, with Centerlock or 6-bolt hubs, and in the color Black.
