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.

The trails in our neck of the woods get pretty hairy pretty fast, so we've found them to be the perfect testing ground for fast and tough wheels like our Traverse 29 Carbon. The steep climbs and descents helped inspire some pretty radical designs, and most importantly, left us with no doubt that these wheels will exceed your expectations. Let's talk about those expectations. They include everything from the ability to stay true after launching off drops to being light enough to efficiently pedal to the top of a climb, and they all begin with the rim. Our engineers knew they wanted carbon fiber, and with the inclusion of our Zero Bead Hook design, they were able to implement a continuous fiber layup across the sidewall and rim bed. And when paired with a whopping 30-millimeter internal rim width, they made a wheel that's super resilient to impact with low rolling resistance and incredible traction. You'll also find that it helps prevent "burping" during hard cornering, while also making tubeless set up quick and easy. Along with light overall weight, stiffness, and durability, another top priority for the Traverse was ease of use. First off, we got rid of the creaky straight-pull spokes and corrosion-prone alloy nipples. Next up, we landed on 28 J-bend spokes, for front and rear wheels, that are all the same length, making it easy to find replacements if needed. And finally, we engineered a new hub design with a wider profile and higher flange to aid in overall stiffness. A wider rim does a variety of things for ride performance, better supports the tire for increased confidence and grip, and it affords you the ability to run lower pressures that help spread impact out over a larger surface area to reduce the risk of damage. And when you combine this girth with the notoriously fast rolling 29 platform, you're left with an incredibly stiff, quick to accelerate wheelset that climbs just as well as it shreds descents. After designing the perfect trail rim, we kept our lightweight and durable design properties in mind with the wheel build, hand-lacing the rims with DT Swiss 350 Classic hubs via 28 DT Swiss Competition Race spokes and brass Pro Lock nipples. Inside, you'll find sealed cartridge bearings and a 36t quick engagement ratchet system for quick accelerations. We also wanted to ensure that each wheel was built correctly, and we found that this could only be achieved by hand. Machines, we found, have a tendency to miss little mistakes that humans catch. Each wheelset comes packaged with a SRAM XD driver, 11-speed freehub, and a tubeless valve stem in order to make tubeless set up a touch easier. *Please note that Shimano freehubs are sold separately. - Assembly Method: Hand built at every step; from rim layup to the last nipple turn. - Bearing Type: DT Swiss Sealed Steel Cartridge Bearings - Extras: 19 and 31mm OD end cap options included, Roval tubeless tape and tubeless valve, Spare Spoke and Nipple Kit, System Weight Limit: 240lbs / 109kg - Hub: Roval DT Swiss 350 J-bend, 6-bolt, Star Ratchet 36t internals (10 deg), 110x15mm & 142x12mm thru-axle, SRAM XD Freebub, (Convertible freehub and endcaps) - Nipple: DT Swiss Hex Prolock Brass 2.0x14mm - Rim Details: 25mm Depth, 35mm External Width, 30mm Internal Width, ERD 594 - Rim Type: Traverse Carbon, 29, Disc Brake, Tubeless Ready, Zero Bead Hook Design - Spokes: DT Swiss Competition Race J-Bend, Front: Two-Cross 28 count, R: 282mm, L: 279mm, Rear: 282 Two-cross 28 count, DS: 280mm, NDS: 281mm - Tire Size: 1.95 - 3.0 - Max Pressure: 40 psi - Weight: Wheelset 1,800g (including tubeless rim tape and tubeless valve)

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
