Mavic’s XA Pro Wheelset takes aluminum rims wider and lighter, using all their proven technology to get you a great wheel that improves trail riding beyond what you thought possible. The 25mm wide internal cavity is designed to make 1.8-2.5” (46-64mm) tires grip better and roll faster with less air pressure. The size and shape of the tire, and how much air pressure is behind it can dramatically change how your bike performs. The changed tire shape puts more tread on the ground. The increased air volume means that if you drop the pressure a little bit, you’ll get the tire to deform more easily without bottoming out The rims have the technology that Mavic employs to take aluminum beyond what most think possible. Maxtal aluminum alloy is used to fabricate the rim. Then it is joined via their SUP process, and milled to be as light as possible via their ISM (Inter Spoke Milling) program. Spoke nipple holes, rather than being drilled through the rim are only made on the hub side, leaving the rim side smooth. This is their FORE process. Stronger, a sealed cavity, and no need for tubeless tape. The wheels can be run tubed or tubeless. Mavic supplies tubeless valves with the wheels as most go tubeless and Mavic wants to improve the wheel wherever they can. Aluminum spoke nipples only go the inside rim wall and are secured to Mavic’s aluminum, double-butted, bladed, straight-pull Zicral spokes. The spokes, 24 front and rear, are laced cross-two in front to deal with the rotor-induced forces, while the rear has Mavic’s Isopulse lacing, radial on the drive side and cross-two on the rotor side. The hubs are set up with Mavic’s QRM+ sealed cartridge bearings. They come set up to run as 15mm thru-axles in front and 12mm through axles in the back. The cassette body is a SRAM/Shimano compatible eleven-speed body. These wheels are rated ASTM category three: appropriate for cross-country and trail riding.

Zipp's 3ZERO MOTO carbon enduro/trail wheelset is inspired by moto to provide riders with the control and durability required for pure speed. Moto remains a powerful source of inspiration for good reason. Based in the racing hotbed of Indy, Zipp for more than three decades has used motorsports as an inspiration to develop pioneering carbon cycling innovations. Zipp's single-wall approach, Moto Technology, allows the rims to "pivot" from either side of the spoke bed while traversing rough terrain. As the wheel encounters obstacles, each edge of the rim is designed for compliance, creating the feel of extra suspension. For the rider that means durability and control for greater speed. Moto Inspired. Control + Durability = Speed - Single-wall design called Moto Technology - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners, smoother ride in rocky terrain - Ability to run lower tire pressure - Rim is designed for compliance, creating the feel of extra suspension - ZM2 Hub - E-MTB approved - TyreWiz tire-pressure monitoring device sold separately

Zipp's 3ZERO MOTO carbon 27.5 enduro/trail wheel is inspired by moto to provide riders with the control and durability required for pure trail speed. This wheel and its MOTO Technology have already been proven by multiple victories in the Enduro World Series with our pioneering partnership with the Lapierre Zipp Collective. While other wheel brands limit their focus to traditional box-section rim designs, Zipp engineers—uninhibited by legacy technology—took a different approach. They looked to motorsports as a model. Zipp's Moto Technology's single-wall rim is the optimal approach for an enduro/trail wheelset. The resulting rim provides something we call "ankle compliance." Imagine a runner rounding a sharp turn, the ankle naturally flexing to maintain grip as the runner leans. The 3ZERO rim can locally flex to stay parallel to the ground during cornering, increasing traction like a human ankle adjusts while running. This ability to twist locally allows it to deflect during single bead impacts without the rider getting bounced offline. 3ZERO MOTO helps you take the most direct route, saving seconds when and where they count most. At the center of the 3ZERO MOTO is the ZM2 hubset. This German-engineered hubset features 12 pawls and 132 points of engagement for a quicker response. The hub's improved seal design means better durability on rough terrain. Quarq's TireWiz is an add-on option for 3ZERO to dial in your pressure for an even more compliant ride. - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners - Smoother ride in rocky terrain - Ability to run lower tire pressure - Reduced rider fatigue - Frustration-free tire installation - Rim is designed for compliance, creating the feel of extra suspension - German-engineered hubset features 12 pawls and 132 points of engagement for quicker response and also has improved durability - Lifetime Warranty

The Arch MK4 is the wheelset a lot of us here at Stan's choose to ride. All-mountain, Downcountry, Trailduro—whatever they're calling it this week, when you like pushing your limits on climbs, descents, and every kind of trail, this is your wheelset. The Arch MK4's 28mm internal width and patented lightweight, low-profile design is not afraid to climb, while being an absolute monster on the descents. With a welded seam, reinforced spoke bed, and durable 6069 aluminum construction, the Arch MK4 rims give you the confidence to ride everything. When it comes to a consistent and reliable airtight tubeless seal, nothing beats Stan's patented Bead Socket Technology. The Arch MK4 rims feature an asymmetric design with offset spoke holes to improve spoke angle and create a stronger all-around wheel. Unlike most asymmetric rims that suffer from difficult inflation and poor tubeless performance, Stan's BST-Asymmetric design delivers all the advantages of a stronger wheel, with no compromises in tubeless performance. Nobody likes downtime, so the Arch MK4 wheelset is built with traditional J-bend spokes based on their proven strength, ride quality, and easy serviceability. Stan's has always made it easy to find replacement spokes should you ever damage your wheel, and now we've made it even easier. MK4 front and rear wheels of the same diameter all use the exact same very common spoke length, both sides, front and rear. Serviceability doesn't get any easier than that. From the first click of the incredible M-pulse hubs, it's clear that confidence is the philosophy behind every part of this wheelset. Designed and CNC machined by Project321 in Bend, Oregon, M-pulse freehubs feature 6 pawls with Neodymium magnets that lock into place with greater force than conventional pawl springs, but offer virtually no resistance when coasting. Multiple teeth on each pawl offer better load distribution for years of trouble-free riding, and the angle of the pawls was engineered to transfer stress away from the rotating bearings, decreasing stress and wear on the entire freehub. That durability extends to the 17mm axles machined of 7075 aluminum and the full complement of Enduro brand bearings, including a double-row freehub bearing. M-pulse internals are also fully shielded inside the hub, because the only thing better than a good bearing seal is a good bearing seal most dirt can't even reach. As durable as they are, these hubs are also built for speed. M-pulse hubs engage with only 1.66°of rotation, putting down power nearly instantaneously, but how smooth these hubs roll is what really stands out. Adjustable preload allows you to fine tune M-pulse hubs for reduced friction, and less drag means more speed on the ground.The result is a bombproof hub with quick, consistent engagement and less resistance for more speed. Available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations. Tubeless ready with rim tape installed. The Arch MK4 is our most versatile wheelset, and the best aluminum wheelset available for riders who want to push limits on every trail. Up, down, and wherever the ride takes you, the Arch MK4 wheelset has it under control. - Arch MK4 wheels include pre-installed tape for tubeless use and presta valves. - Versatile 28mm internal rim width optimized for 2.2-2.5” tires - Light and durable 6069 aluminum with welded joint and reinforced spoke bed - BST-Asymmetric design combines Stan’s legendary easy tubeless inflation with a stronger, more balanced wheel build - M-pulse ultra-low drag magnetic pawl adjustable hubs with 1.66° engagement - Enduro bearings with double-row freehub bearing - Matched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceability - Connection program includes 5-year hub warranty, 3-year rim warranty, 1-year crash replacement, and $10 donation to trail maintenance or advocacy group of your choice
