Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With a disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. A new carbon fiber layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while SRAM's robust 77/177D hubset keep the wheels stiff and responsive. Each Wheel Includes: - Zipp Tubeless valve extender and valve-core wrench - Zipp rim tape (factory taped) - Zipp Tangente quick-release skewer - Zipp thru-axle end caps

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless wheels are for dedicated cyclists who aspire to the latest in technology. They're for those who compete in races, against peers, or simply to conquer personal limits. - New Zipp graphics and cosmetic identity that scream speed - Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile - Lighter weight than its predecessor, making it nimble and fast - Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. - Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road - 40mm rim depth makes a light and aero wheel in every situation - Ships with 12mm end caps - Center Lock rotor interface (lockring included)

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 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 i23 gravel wheels are designed to minimize weight while blending stiffness and compliance to maximize power transfer and increase comfort. CZR i23 rims feature a 24mm section depth to maximize energy transfer, reduce weight, improve vertical compliance, and reduce rider fatigue while a hooked bead also improves tire retention with high pressure adventure road and gravel tires. CZR I23 CARBON RIMS Reinforced spoke beds improve overall wheel strength and durability while also minimizing weight in areas where less strength, and therefore material, is needed. CZR i23 rims feature 3mm of asymmetrical spoke offset and a 24mm section depth to improve radial stiffness and maximize energy transfer without being affected by crosswinds like other wheels with deeper profiles. 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. 2-CROSS OR 3-CROSS LACING CZR i23 gravel wheels with 24 spokes feature a 2-cross lacing pattern to increase radial stiffness and decrease weight. CZR i23 wheels with 28 spokes feature a 3-cross pattern to increase durability while still providing ample radial stiffness due to the additional spokes. FREQUENCY HUBS 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. Frequency hubs laced to CZR i23 wheels feature lightweight pawl springs that minimize drag and therefore improve efficiency for drop-bar usage. AERODYNAMIC WING SPOKES Pillar racing spokes that are cold-forged into an aerodynamic wing shape that reduces drag at the trailing end of each spoke. As a result, wing spokes improve overall efficiency while still retaining the gram-conscious weights of traditional bladed spokes. SAPIM ALLOY NIPPLES All CZR i23 wheels feature time-tested Sapim alloy nipples to further reduce overall wheel weight while still exceeding the durability requirements of gravel. COUNTLESS CONFIGURATIONS CZR i23 wheels are available in a 24-spoke option for riders looking to minimize weight and increase compliance, while the 28-spoke versions are best for heavier or more aggressive riders who prioritize stiffness and durability. All CZR i23 wheels are available with Centerlock or 6-bolt rotor mounts. CZR i23 front wheels use a 12x100mm Frequency hub, but 15mm end caps are also available separately on our Replacement Hub Parts page. WHY CHOOSE CZR I23? Fast and light CZR i23 gravel wheels were designed to minimize weight and maximize compliance on rough gravel roads. With front-wheel weights starting at 620g and rears at 775g, they also deliver the greatest strength-to-weight ratio of any gravel wheelset on the market. We even stand behind them with our Ride With Confidence Guarantee for those few-and-far-between crash replacement cases. Read below for more info.

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.
