Zipp's 353 NSW Tubeless Disc-brake wheel is the pinnacle of our pursuit of versatility and speed. This wheel fuses Zipp's two most advanced approaches, Sawtooth rim profile and TSE, for an all-encompassing approach to performance. With its undulating 45mm-deep rim shape, the 353 NSW provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. The 353 NSW is Zipp's lightest tubeless wheel yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of hookless (straight side) rims in the 353 NSW is integral to achieving our mission of Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. Zipp's 353 NSW's Sawtooth rim shape with Hyperfoils optimizes aerodynamic efficiency and crosswind stability. The Sawtooth design also allows the rim to be structurally strong but light. That will help you snap out of corners and maintain that speed no matter the terrain, especially in the steep, punchy stuff. The 353 NSW utilizes Zipp's Total System Efficiency, or TSE, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheel's 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the center of the 353 NSW is the Cognition V2 Hubset, re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction, as well as improved durability. - Versatile endurance wheel for the modern road bike with tubeless and hookless rim profile - Our lightest tubeless wheel yet, making it a fast-puncher ready to fight - Optimized tire bed for easy tire installation - TSE for greater efficiency and reduced rolling resistance - Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stable performance with an undulating rim depth - Cognition V2 hubset rolls efficiently whether you are pedaling or coasting.

Perfect for flatter courses and time trials, the DURA-ACE C60 prioritizes aerodynamic efficiency and lateral rigidity. The new hub design, stiffer spokes, and deep-section rim are designed specifically to allow you to push harder in corners and ensure that every bit of your effort is translated into forward motion. Like the entire DURA-ACE wheel family, the new C60 started with a blank slate. Different from the C36 and C50, the C60 has a specific front hub design using Shimano's OPTBAL 2:1 spoke pattern to enhance lateral rigidity. The C60 also receives stiffer spokes, 1.8 mm instead of 1.5 mm. Tested by our professional athletes, this focus on the lateral rigidity of C60 allows you to push harder in corners and when maneuvering at higher speeds. Lastly the new wind-tunnel tested, deep section rims feature a faster, more stable cross-section that time trialists, triathletes, and sprinters alike will enjoy. - HR: High-Rigidity ver. +20% increased lateral rigidity for powerful riders and sprinters - 60 mm height full carbon rim - Internal rim width: 21 mm - DIRECT ENGAGEMENT - Compatible only with Shimano road 12-speed cassette sprockets

Since 2020, Rapide CLX wheels have won more races on the world tour than any other wheels, and we just made them faster. Meet the new Rapide CLX II. Combining the aerodynamics of a deep-section TT wheel with the light weight of a shallower climbing wheel and mixing in the superior efficiency and sublime handling of a tubeless system-the Rapide CLX II delivers maximum speed for real-world riding. We developed distinctly different shapes for the Rapide CLX II front and rear rims. The result is a wheelset that catches less drag than most 65mm wheelsets and brings a dramatic 25% improvement in stability over 50mm rims in wind gusts. The Rapide CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if that's your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible. Our aeroflange hubs are aerodynamically optimized, with wide bracing angles for increased strength and reduced spoke weight.

First came our CLX 64. Then the 32s. And after racking up multiple wins in Grand Tours, Worlds, and everything in between, we knew that our best bet was to take the line to new heights, or well, new depths. We needed to design one wheel that was a true quiver killer. One wheel that had all the aerodynamic benefits of the 64 in a package that climbed like the 32, and that's where the all-new CLX 50 comes in. When we set out to create the CLX 50, we had clear goals in mind, create wheels that are 48 to 54mm deep, aerodynamically optimized, ultra-wide, and under 1400 grams. This meant that they'd have to borrow some weight savings techniques that we developed for the CLX 32, while taking some aero guidance from the CLX 64, if we were going to create what we like to call ""the unicorn wheel."" Even though the CLX 50 is similar in weight to many wheels in the ""lightweight"" category, aerodynamics came at the forefront of the development. With this, we jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CLX 50 as fast and light as possible. It took a while, but we narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel. In the tunnel, we tested every wheel, ours and the competition's, with a 24C tire (measuring 26C), as tires can drastically affect testing. We chose a modern-width tire to design our rims around, because they not only allow for less tire pressure (which results in more comfort and less rolling resistance) but are also just as aerodynamically efficient when paired with the correct rim width. After finding the optimized rim shape that supported our svelte weight requirements, we opted to lace the rims, via 21 DT Swiss Aerolite spokes, to our Aero Flange (AF) hub with the legendary CeramicSpeed bearings and DT 240 hub internals. And when it was time for final testing validation, we were left with a 50mm-deep, 770-gram clincher wheelset that's not only 200 grams lighter than the competition's similar depth wheel, but is also measurably faster in every conceivable test than each wheel in its category. - Assembly Method: Hand-built - Brake Track Height: 12mm - Braking Surface: Carbon Fiber - Extras: Roval padded wheelbag, Roval steel quick-release, Roval tubeless plugs and tubeless valve, SwissStop Black Prince brake pads - Nipple Type: DT Swiss Pro Lock hexagonal - Rear Hub: Roval AF1, CeramicSpeed bearings, DT Swiss 240 internals, 11-speed - Rim Depth: 50mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 20.7mm internal, 29.4mm external - Spoke Count: 21 - Spoke Pattern: Radial/Two-cross (2:1) - Spoke Type: DT Swiss Aerolite T-head - Weight: 770g

WHAT IT'S FOR, WHY IT'S GREAT From weekend hot laps to World Cup XC finals, the Control Carbon combines the low weight and strength found in our world-beating Control SL rim with the new DT Swiss 350 hubs. An unmatched level of durability, precision, and performance in this new Carbon Control wheelset that is purpose-built to open terrain, from gut-wrenching climbs to tear-inducing descents—a whole new era of riding. A high-performance wheel that excels everywhere from world cup xc races to your favorite weekend trail. The Control Carbon combines the low weight and strength found in our world-beating Control SL rim with the new DT Swiss 350 hubs and spokes. This level of quality, precision and performance has previously been found only on wheels costing twice as much. ASYMMETRY BEGETS SYMMETRY The asymmetric design of the Control rim offers some subtle but important benefits. With the spokes offset to one side of the rim, this allows us to reduce the spoke offset that usually occurs at the hub. In turn, this means we can generate greater bracing angles for the spokes between the hub and rim, while also minimizing the spoke tension differential that often occurs between drive- and non-drive side spokes. The end result is a wheel that is stronger, laterally stiffer, more durable, and in the case of the Control, allows us to utilize the same length spoke throughout the whole wheelset. MINIMUM WEIGHT, MAXIMUM DURABILITY, EASY SERVICEABILITY Striking a no-hassle balance between low weight and low maintenance, we chose DT Swiss 350 Classic hubs (15x110mm thru-axle front, 12x148mm thru-axle rear) as the basis for the Control Carbon wheels. With sealed bearings, a notoriously durable 36-tooth ratchet, and 28 spokes front and rear, dependability is assured. QUALITY THROUGHOUT, FROM HUB TO SPOKE TO NIPPLE TO RIM There is absolutely no point in laying up an awesome rim and pairing it with a quality hub, only to skimp on spokes and nipples. So, keeping strength and dependability foremost in our minds, we opted to hold the Control Carbon wheel together with the best: DT Swiss Competition Race spokes and alloy Pro Lock nipples.

Taking the notion of combining flagship performance with workhorse dependability one step further, we're introducing the Terra C. This shares the same hub and spoke architecture as the Terra CL, ensuring ease of service and spoke replacement, should the need arise and is paired with an entirely new rim layup. The rims on the Terra C share the same dimensions and broad range of tire mounting possibilities as the Terra CLX and CL—33mm deep with a 25mm internal width—but are crafted using a new-to-us process known as Resin Transfer Molding. This is an automated process that allows us to very precisely control how resin is introduced to the layup, which in turn ensures maximum strength and material performance. The end result is an incredibly tough set of wheels that you can beat on to hell and back. - Rim: Terra C RTM Carbon Clincher, 700c, Disc Brake, Tubeless Compatible - Rim Details: 32mm Depth, 30mm External Width, 25mm Internal Width; ERD 577mm - Hub: DT Swiss 370 J-bend Center Lock, Ratchet LN 18t internals (20 degs), 100x12mm & 142x12mm, Shim.

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)

Feel your bike come alive on the open road with the new Alpinist CL II, featuring the lightest, best-handling clincher rims we have ever made, elevated with the performance of a tubeless system. The brand new Alpinist CL II now brings mountain-taming performance slightly closer to earth with a carefully selected build designed to let riders take full advantage of the low rim and spoke mass. The Alpinist CL II utilizes the same rim as the alpinist clx ii. They react to even the slightest increase in power with immediate acceleration and carve the purest lines in the corners, yet they can also handle almost double the impact standards of every certifying body. The result is a 1375-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures. The Alpinist CL II utilizes components curated to keep you rolling and rolling fast. The DT Swiss 350 hubs, featuring their star ratchet drive system, are reliable and easy to service, while 24 DT Swiss comprace straight-pull spokes front and rear, laced to the rims with their alloy pro lock nipples, are synonymous with reliability and can be obtained at any bike shop. The reduced rolling resistance of a tubeless setup is undeniable, as are the benefits of improved handling and incredible puncture protection. It took the most extensive and demanding engineering and testing program we've ever undertaken. As a result of this extensive development, the Alpinist CL II features a hooked rim that can handle a huge range of pressures up to 110psi and offers an easier set up and mounting experience than ever. - Rim: Alpinist CLX Carbon Clincher, 700c, Disc Brake, Tubeless - Rim Details: 33mm Depth, 27mm External Width, 21mm Internal Width - Hub: DT Swiss 350 Straightpull Center Lock, Star Ratchet 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

While there may be a linear relationship between increased tire size and increased fun, this relationship only holds true when wider tires are paired with the correct width rims. Having a 2.8", or high-volume, tire mated to a narrow rim makes for a squirmy, poor handling experience, and when you’re on the hunt for additional fun, these characteristics are undesirable. Lucky for you, the new age of traction, stability, and speed has arrived—and its name is the Traverse 38 SL Fattie 27.5. Along with light overall weight, stiffness, and durability, another top priority for the Traverse SL 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. While our 38-millimeter Traverse SL is already wider than most offerings, the benefits of three-inch tires become more apparent with a proper rim interface. In search for the proper width, our engineers tested various iterations, from 30 to 45 millimeters, to determine where the sweet spot lies. What they ended up with is a 38-millimeter internal rim width that turns the Traverse 38 SL Fatties into descending machines. A wide internal rim width endows riders with a variety of advantages that are exemplified even more with plus-sized tires. The extra width allows for more tire volume, translating into more supple ride qualities, and better support for the tire, meaning that you'll experience less "burping" when riding tubeless and a drastic increase in traction. After determining the proper rim width for the plus-sized application, we began designing the rim using the same low-weight, high-strength technologies used in the Traverse SL and the Control SL. With this, we started with our Zero Bead Hook design that effectively eliminates the biggest weak spot found in traditional rims, and topped it off by using high-modulus carbon fiber to keep the weight down. And to further this theme, the wheels also include the Roval tubeless plug system, which sheds an additional 50 grams-per-wheel compared to a rim strip Each Traverse 38 SL Fattie is hand-built to our own alloy hubs with DT Swiss Competition Race spokes. Inside our hubs, you'll find sealed cartridge bearings all-around, and a quick-engaging 54t DT Swiss star ratchet system in the rear that allows you to power over rocks and roots without delay. And while machines do a decent job of building wheels, we choose professionally trained humans to build ours, as they catch various flaws that a machine would otherwise miss.

Trail wheels often fall into two categories—they're either heavy and durable or light and flexy. And because of this, a lightweight, wide-profile, and enduro-ready carbon wheel seems like something only found in a fairytale, but lucky for you, we made it a reality. The Traverse SL Fattie 27.5 puts all the flickable, nimble features you need in an all-mountain wheel into one package, and it has the results to prove it. Along with light overall weight, stiffness, and durability, another top priority for the Traverse SL 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 both the 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. What's with the big-boned name, you ask? The Traverse SL Fatties may be wide, but with a 30mm inner rim width, they're far from the girth of a fat bike rim. But let's talk width. You've probably noticed that mountain bike rim widths have hovered between 19 and 23 millimeters for decades, and they've been long overdue for a change. In the search for a better wheel design, our engineers began testing 2.3- to 2.5-inch tires on 45-millimeter-wide fat bike rims to see what, if any, benefits could be found. It only took them a few rides to realize that the wider rims offered a variety of advantages, like adding additional tire volume, which better supports the tires in hard cornering, greatly improves traction because of the ability to run lower pressures, and noticeably increases rim stiffness. They did note that there is an occurrence of diminishing returns with increasing width, however, and after testing everything from 25 to 45mm, determined that a 30mm inner width is optimal. After determining the width, we began designing the rim using the knowledge that we gained when developing the Control SL. With this, we started with our Zero Bead Hook technology that gets rid of the weak spot found in a traditional wheel, and combined it with the wider profile to make a carbon rim that effectively dissipates forces. This way, you can take abuse from rocks without the worry of cracks or dents. Ok, so they're strong, impact-resistant, and tire supporting-they must be heavy, right? Wrong. Even though "fattie"? is in their name, they're far from fat. To achieve this weight, we hand-build our rims to our own alloy hubs, using only the highest quality DT Swiss Competition Race spokes. Inside our hubs, you'll find DT Swiss 240 internals with a quick engaging 54t DT Swiss star ratchet system in the rear that allows you to power over rocks and roots without delay. And while machines do a pretty good job of building wheels, we choose professionally trained humans because they do so with an artistic touch that makes for minimal flaws.
