Riding is believing with the Zipp 1ZERO HITOP SW MTB wheelset when it comes to making you faster. Trail compliance is vital, with modern cross-country races becoming rougher and more challenging. No longer is it good enough for an XC wheelset to be stiff above all else. Instead, a wheelset should feel alive. The 1ZERO HITOP SW carbon rim complies with the terrain thanks to Zipp's proprietary HITOP Technology for carbon layup. The result is a lightweight XC wheel that carries speed through all sections of the trail, rocks, roots, and ruts with the durability required for a trail bike with up to 130mm of travel. A compliant wheel provides more confidence. You don't have to work hard to spin it up to speed or fight your bike when things get chunky. The 1ZERO HITOP SW also comes with the TireWiz tire-pressure monitoring system, so you'll always have your tire pressure dialed in for optimal performance. Among the lightest on the market, the ZM2 SL hubset ensures you'll be quick to accelerate and back on the pedals sooner after corners with the 1ZERO HITOP SW. - HITOP Technology produces proprietary rim layup to provide compliance and confidence when the trail gets rough - Low weight for effortless accelerations and climbing - Winged rim provides a smooth resting surface for the tire, reducing the chance of pinch flats after a rock hit - TireWiz 2.0 tire-pressure monitoring system features a seamless design - ZM2 SL hub with 66 points of engagement - Standard or Torque Cap options on the front hub - XD or Microspline driver-body options - Lifetime Warranty

Zipp's 3ZERO MOTO carbon 27.5 and 29 enduro/trail wheelset is inspired by moto to provide riders with the control and durability required for pure trail speed. This wheelset 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 improved seal design for 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 - Lifetime Warranty

CZR i30 wheels were designed to handle it all, which is why they feature a strategically reinforced carbon layup and are hand built using double-butted spokes, brass nipples and high-engagement hubs featuring top-tier bearings and oversized freehub seals to establish themselves as wheels that simply won't quit. Solid Strip & TCS Tape - Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke. 3-Cross Lacing & Brass Nipples - Too many companies are trying to save weight by offering "enduro" wheels with 2-cross lacing patterns and inadequate alloy nipples. While those are suitable for XC and light trail usage, there's no replacement for the long-term reliability of a 3-cross lacing pattern with brass nipples holding it all together. Frequency Hub - The world's best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement. Heavy-Duty Pawl Springs - CZR i30 wheels feature heavy-duty pawl springs that engage with greater force to counteract the additional torque caused by sudden cranking on steep trails. We also offer a Light Pawl-Spring Kit that can be purchased separately for CZR i30 riders who prefer a quieter hub with lighter pawl engagement. Usage: Trail, Enduro

Stan’s S1 wheelset line brings patented tubeless technology to an even wider range of riders. Built for long life, low maintenance, and outstanding value, the S1 series wheels feature 6061 series alloy rims and are available in six different widths suited to a wide range of tire sizes and riding styles. With an emphasis on value and durability, the S1 alloy wheelsets join a mountain wheel line-up that currently includes Stan’s successful MK3 premium alloy wheels and innovative Valor and Bravo carbon series wheelsets. While MK3 wheelsets are built to balance strength, light weight, and stiffness, S1 wheelsets focus on maximum strength and durability. The deeper profile and thicker walls of the S1 rims result in a 50-70g weight increase over MK3 rims, but offer greater impact strength for an even wider range of use. “The new S1 series wheels were developed from rims ridden in Redbull Rampage and raced on the World Cup DH circuit for years,” said Creative Director, Chris Currie. “The goal was to take everything we’ve done for tubeless technology, and put it into a truly bombproof and affordable wheel.” Designed according to Stan’s WideRight rim and tire fit system, S1 series wheelsets are available in six different rim models, with internal widths ranging from 23mm to 38mm. Combined with Stan’s low-profile, high-volume Bead Socket Technology rim design, these widths let the new S1 range accommodate tires from 2-inch to 3.5-inch. All S1 wheelsets are built with 32 spokes front and rear, Sapim’s proven Race spokes, Secure Lock brass nipples, and Stan’s faster-engaging Neo hubs. Hubs are available to fit most axle systems, including Boost. The S1 series includes reinforced versions of the classic Crest, Arch, and Flow--names already familiar to fans of Stan’s tubeless rims. In addition to the Crest S1, Arch S1, and Flow S1, three entirely new wider wheelsets will be available. The Sentry S1, Baron S1, and Major S1 bring Stan’s patented Bead Socket Technology to Plus bikes. Flow S1 Wheelset - Use: Aggressive Trail, All Mountain, Enduro, and Downhill - Internal Rim Width: 29mm - Optimal Tires Size: 2.35 to 2.8-inch - Hubs: Stan’s Neo 32-hole Front, 32-hole Rear - Spokes/Nipples: Sapim Race Black 2.0/1.8/2.0mm, Secure Lock Brass Silver Nipples - Wheel Sizes and Weights: 27.5-inch (2,034g), and 29-inch (2,134g)

What It Is The definitive mountain wheel. The M6 Series defines the modern and varied interpretation of the mountain bike. Loaded with traction and acceleration on the climb, it's also backed with precision and control while absorbing vibrations and impacts on the descent. The M6 Series is designed in two diameters and three widths to ensure your sophisticated preference for tire size and pressure is met with an uncompromising tire-to-rim interface. Who It's For The mountain biker who wonders what is possible, the skeptic afraid of "plastic" wheels, the weight weenie, the Clydesdale, the high-mileage guy, the weekend warrior. It would be easier to describe who it is not for… Why We Made It ENVE showed the world that a mountain bike wheel could be carbon — we're still immensely proud of that achievement. A mountain bike wheel, however, can be so much more. The M6 Series is not about technical challenges, and we refuse to chase specifications in order to be the widest, tallest, or stiffest. For the M6 Series of wheels, the question was not about carbon, rather, "What is the potential of a mountain bike wheel?" Each M6 Series wheel model is designed for the broad range of tire widths, hub configurations, and sizes so that you, the modern trail rider, can choose between them.
