M525 Industry Nine Hydra 29in Boost Wheelset
When the sport began, traditional cross-country racing was a sport for the strongest riders, with power to soar down smooth ribbons of singletrack, but with shifts in technology, terrain, and skill, we see more demanding courses that favor the fittest and most technically savvy riders on the mountain. We certainly think that these more technical trails make for more fun, both as spectators and racers, but with that shift they also demand more from the equipment we ride on. After all — current cross-country steeds rock the head tube angles and travel that we saw on all-mountain machines in years past. As such, rims have gotten wider to meet needs for reduced rolling resistance, and increased tire volume, and we crave snappier hubs to match for near instant engagement. Taking what it has learned in the lab and from racer feedback, ENVE constructs theM525 Industry Nine Hydra 29in Boost Wheelset to satiate your craving for featherweight wagon wheels to soar down the singletrack.
ENVE received valuable feedback from their World Cup races and in house rippers when it came time to redesign the already excellent M50 rims. A goal of dropping weight was a priority as well as increasing the width for the newer crop of wider tires. Naturally durability could not falter and engineers actually looked at ways to increase rim reliability and reduce the risk of cutting lightweight tires often when run at lower pressure. In doing so, World Cup racers and the weekend warrior can enjoy the benefits that come from reduced air pressure and charge harder knowing that the rim can handle the abuse. The proof is in the pudding they say, and after a few bites, we have to admit that this pudding is tasting pretty sweet.
The hookless bead first appeared on ENVE mountain wheels on the last generation's MSeries. It was certainly an improvement over the XC rim of old with regards to tubeless setup, durability, and weight savings but ENVE knew they could do better. Meet the M525. This all-new, wider hookless bead is the culmination of over 2 years of development met to address both rim and tire durability. The rim shape features a broader leading edge on the bead which creates a more forgiving platform for the tire to bottom out, thus reducing the likelihood of pinch or snake-bite style flats. The design also allows for greater impact resistance for the rim when smashing it through that rock garden on the last lap. You can confidently run lower tire pressure to improve both traction and rolling resistance. The internal width has grown significantly as well, increasing from 21mm internally on the M50 to a healthy 25mm on the M525. Tire profiles are significantly improved for better cornering stability, braking, and rolling efficiency.
What isn't lost on these new wheels are the phenomenal ride quality ENVE is known for. The team consistently rides samples blind, and have their professional athletes do the same, to evaluate the exact carbon laminate, resin, layup, spoke count, and even lacing to achieve the desired ride qualities for the wheel's intended use. The M525 is a no-compromise cross country wheelset and as such, its construction is chosen for greater vertical compliance for the long hours in the saddle reducing fatigue without sacrificing the impressive lateral rigidity that corners like it's on rails. The hole count is reduced from 28 to 24 again to improve the ride and shed every gram possible.
Unique to every ENVE rim is the patented molded in-spoke holes, nipple seats, and valve holes, offering the highest strength-to-weight ratio in the industry. The nipple pocket is super strong and pull through is a thing of the past. When laying up the rim, ENVE places pins in the layup at the spoke hole locations so it can maintain continuous fiber integrity versus the industry standard of drilling post cure, which cuts into the fibers and weakens the structure. This results in increased rim rigidity, a stronger anchor point for the nipples and weight savings at the spoke face.
The internal nipples are able to articulate in their pockets much like a ball-and-socket joint. This yields a higher and more uniform spoke tension key to strong, true wheels from day one and throughout the many years of ownership. To save every gram possible, ENVE removes the bladder after curing where other composite manufacturers leave the rim-shaping, inflatable bladder in the rim. This process takes more time and expertise, but the end result is a lighter wheelset and one that is more perfectly balanced.
This particular build sees the 29-inch M525 rims laced to the Industy Nine's applauded 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.
