M640 Industry Nine Hydra 29in Boost Wheelset

It's hard to beat the plush feel of massive volume tires on the trail. Whether their increased traction has you sold, or its that additional pneumatic suspension that soaks up square-edge bumps, having a bigger tire can increase confidence cornering, and make for a more comfortable ride, though at the cost of heavier rubber. ENVE's M640 Industry Nine Hydra 29in Boost Wheelset is built to find a happy medium, with lightweight carbon rims that meld together speed, performance, and weight savings, while providing a serious backbone for your plus-sized tires. This iteration of the M640 also ads in Industry Nine's new Hydra hub, for extra snappy engagement at 0.54-degrees, for instant propulsion when you're booking it up steep climbs and straightaways.

The 29-inch M640 rim weighs in at 485g, which is pretty impressive given the wheels intended trail use on bikes up to 160mm of travel and the fact that it has to provide a excellent tubeless seal and support the extra leverage that comes from running 2.7 through 3.2-inch tires run at very low pressures. A good chunk of the weight savings comes from the wide hookless beads. They're lighter and offer better impact resistant for the rim against the trail and an excellent buffer for the tire, preventing pinch flats while running low tire pressures. That 40mm wide internal rim width is solely optimized for plus size tires and it helps achieve a rounder tire profile translating to greater cornering stability and more rubber on the ground at any given time.

ENVE spent many hours in the lab and on the trail ensuring that the ride of the M640 was classic ENVE. Anyone who’s familiar with ENVE knows the fanatical lengths that its engineers go to in order to achieve a perfect ride feel. As with its narrower siblings, the M640 Plus has been tuned to provide a great degree of vertical compliance, which reduces rider fatigue, without sacrificing the fantastic lateral rigidity that endows ENVE with the “on rails” feeling for which they’re prized, especially important with those plush plus tires.

The rims are always the star of the show when talking about ENVE wheels, but it's also worth noting that these wheels are hand built in Ogden, Utah to exacting standards. This provides the longevity you’d come to expect out of a class-leading wheel system. This particular rim is laced up to i9's new Hydra hub. The Hydra builds on i9's previously used drive system, so if you take a peek at the internals you'll spot a similar pawl layout that we've seen before in the Torch, and the same pristine CNC machining coming straight from Asheville, North Carolina. Like the old Torch hub, the Hydra features a 6-pawl design, but the drive ring amps things up to 115-tooth drive ring, as opposed to the 60-tooth used in the torch. This creates a whopping 690 points of engagement, blowing the 120 points of the Torch out of the water. These 690 points of contact translate directly to the snappiest hubs we've ever seen, with only 0.52-degrees of engagement, propelling you forward telepathically the moment you start to think about putting the power down. Furthermore, the hubs are kept simple for home mechanics, making the hub fully serviceable without any proprietary tools. Additionally, you can choose between a standard HG freehub or an XD driver for use with SRAM’s 1x11 and 12-speed drivetrains. The 240s have become a staple for their lightweight construction, remarkable durability, and tool-free service, which makes them a perfect match on an ENVE wheelset. Boost spaced hubs provide exceptional stiffness and affords frames and forks the clearance necessary to run the wider tires. Mount up the M640 29-inch wheels, and your favorite plus size tires, and prepare to be blown away with unworldly levels of traction and comfort on the trails.
