What It Is An SES featured climbing wheel featuring the latest in ENVE brake track technology. Who it's for Climbing specialists seeking a wheelset that inspires confidence regardless of terrain or weather conditions. Why we made it To give you every advantage when riding through mountainous terrain and unpredictable weather conditions. The Smart ENVE System 2.2 is the ultimate climbing wheel with aerodynamic properties that refine stability in the most extreme wind and weather conditions. As such, lightweight trumps drag reduction with the SES 2.2. The SES 2.2 underwent in-frame development in the Mercedes GP-Petronas wind tunnel in order to define the final shape of the rim. Unlike the other SES wheelsets, the SES 2.2 features the same rim geometry front to rear. In terms of tire fitment, the SES 2.2 is developed to be used with 25mm tires and the clincher version of the rims is tubeless compatible. Because the SES 2.2 is designed to be ridden through the mountains, it was important to improve the performance levels of our molded brake track texture technology. As such, the SES 2.2 is the first SES rim to feature our new molded-in brake track texture. This new brake track texture improves braking performance by as much as 30% over the previous brake track and performs as well in wet conditions as it does in dry. Each SES 2.2 wheelset includes 2 pair of our new black brake pads which have been specially formulated to improve braking power, modulation, and wet weather performance. The combination of the new brake track and black brake pad compound delivers the ultimate in rim brake technology.

What It Is A climbing wheel with an aero advantage designed to be ridden in the mountains. Who it's for Road cyclists who require maximum versatility for riding in mountainous terrain and variable weather conditions. Why we made it Since the introduction of the original SES 3.4, we’ve implemented new design concepts across the SES lineup that result in a faster wheel and improved ride experience. The SES 3.4 features road tubeless compatibility, 25mm tire optimization, molded carbon brake track technology, and optimized SES aero rim shaping to ensure maximum efficiencies for a shallow aero wheel. Equally at home in the mountains as in the valleys, the SES 3.4 is the most versatile Smart ENVE System aero wheel. Like all SES wheel models, the SES 3.4 features dissimilar rim shapes and geometries between the front and back wheels to maximize aerodynamic efficiency and rideability in variable wind and weather conditions. The front rim is 38mm deep and shallower than the rear rim to aid in crosswind stability while rear rim is 42mm deep and therefore improves overall airflow. For riding in mountainous terrain where heavy braking is required, the SES 3.4 features a high-temperature-resistant resin system and ENVE's molded-in brake track technology to ensure rim integrity and precision braking when and where it is needed most.

What It Is The ultimate everyday carbon fiber cycling wheelset and choice of Team Dimension Data. Who it's for Road cyclists and triathletes looking to minimize the trade-off between aerodynamics, lightweight, and stability. Why we made it Because from the moment the first prototypes made the rounds at ENVE, it's been the house favorite.

What It Is The fastest carbon fiber Smart ENVE System aero wheel yet. Who It's For Experienced triathletes and road racers seeking maximum aero performance and stability. Why We Made It We made the SES 7.8 to achieve two things: more speed and more stability. The SES 7.8 embodies the latest SES technologies and includes our newest molded-in brake track and tubeless clincher tire compatibility. The SES 7.8 is wider and specifically optimized to perform best when used with a modern aero frame and large, 25mm tires. Full Details When the race is against the wind and the clock the SES 7.8 is optimized for the task. By reducing the trade-offs between aerodynamics, stability, weight, and stiffness, the SES 7.8 carbon fiber aero wheel is the perfect tool for road racing and triathlon alike. The SES 7.8 features front- and rear-specific rim geometries. The front rim is 71mm deep and 29mm wide, while the rear rims is 80mm deep and 27.5mm wide. The dissimilar rim geometries improve the efficiency of the airflow in the system of bike frame and wheels. Because running 25mm tires is now standard, the SES 7.8 was designed with larger tires in mind. Additionally, frame manufacturers are now producing frames that have more clearance between wheel and frame which has opened up the design scope for a wheelset. The SES 7.8 is optimized for these frames. In addition to changes in shape and structure, the SES 7.8 features the latest molded-in carbon fiber brake track texture and is compatible with road tubeless tires.

The Pro 3-spoke front clincher wheel is ideal for triathletes, time trial cyclists, and any discipline that seeks to maximize aerodynamic efficiency.

1,240 grams is obscenely lightweight when it comes to mountain bike wheelsets—the kind of weight that XC racers dream about—but light weight alone is no longer enough on today’s aggressive XC tracks. So, we sweated all the details and engineered the new Control SL Team LTD wheels to be sharp handling, smooth-riding, extra durable, and less prone to pinch flats. Oh yeah, they’re also some of the lightest production wheels on the planet. We didn’t pull any punches creating the Control SL Team LTD. Built around the lightest hubs Roval has ever made, its completely new rim design with a 29mm internal width provides a better tire profile for improved traction and ride quality. An all-new bead-hook design with wider hooks results in a flat profile that not only offers greater impact strength by distributing impact force over a larger area but also increases the impact force needed to pinch flat by 22 percent. Finally, offset spokes and an asymmetric rim profile paired with two-cross lacing not only provides a better bracing angle for increased lateral stiffness but allows for the use of a single spoke length across the entire wheelset. The end result is a featherweight XC race wheel that excels everywhere from the racecourse to the backcountry. Incredibly low weight matched with above-category toughness and durability, razor-sharp handling, and exceptional ride quality brings out the very best in modern mountain bike performance. Available in very limited numbers, the Control SL Team LTD is meticulously hand-built and finished with a special graphic treatment. - Rim Type: Carbon clincher, 2Bliss Ready, Zero Bead Hook 4mm FlatTop design.

Zipp’s first product almost three decades ago was a disc wheel. It’s at the heart of their heritage. Now, Zipp is pioneering the next generation of disc wheel, the Super-9 Disc-brake Disc. The Super-9 Disc itself, handmade at Zipp's factory in Indianapolis, USA, optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability.The Super-9 disc has an unassuming profile. It borrows from the perimeter shape that makes the Sub-9 so fast it can actually generate forward lift, but in place of the Sub-9's toroidal bulge, the Super-9 remains flat from its widest point all the way to the hub. This relatively simple-looking shape results in a wheel that's as fast as the Sub-9 but stiffer than any other Zipp disc. Braking on modern time trial and triathlon bikes often has been a challenge. The superior performance of disc brakes changes all that with greater stopping power and more precise speed modulation, all with less hand effort than required by traditional brakes. That means greater confidence in corners, descents, and on technical courses. The disc brake version of the Super-9 disc retains the light weight of its rim-brake counterparts. - Includes: Aero Stainless Steel Black Quick Release, 10-speed hub spacer, Platinum Pro EVO Brake Pads, Valve Extender, Valve Adaptor, Valve Decal

Equip yourself with the wheel that carried Tony Martin to a World Championship and reach the pinnacle of your own potential. Zipp’s Super-9 Carbon Clincher Disc underwent extensive fluid dynamic modeling, wind-tunnel testing, and relentless refinement so you can enjoy no-holds-barred aero domination. With a variance in width of just a single centimeter from rim to hub, the Super-9 is almost invisible to the wind. Plus the wide rim creates a virtually seamless integration with the tire, increasing aerodynamics and allowing wider tires run at a lower pressure. This diminishes rolling resistance, increases rider comfort, and reduces the chance of pinch flatting.

Campagnolo has developed a totally reworked disc brake version of the Bora One that transfers skills and knowledge gained in years of experience and introduces a new logic and innovative technologies to ensure unprecedented results. The Bora One Disc Brake is the most sophisticated carbon wheel on the market and one of the few specifically designed for disc brake systems.

The Bora One 50 disc brake is the perfect answer for cyclists wanting to leave their mark on routes with high-speed stretches. Its 24.2mm width maintains high weight and steering standards, offering excellent aerodynamics for users who team it with a 25mm tubular and extremely high levels of comfort and safety when braking for those who prefer to use 28mm tubulars. The result is a pair of carbon racing bike wheels that delivers incredible performance in terms of aerodynamics, stiffness, steering, and reactivity while maintaining the famous smoothness of the Bora. The Bora One 50 disc brake was the first wheel tested by the pro riders on the Campagnolo teams together with the groupsets and it favorably impressed its testers Erviti, Greipel, and Berlato.

What It Is The G27 is the G23's little big brother. Smaller in diameter and lighter in weight, the G27 is designed for the higher-volume tires demanded by many riders on rougher and looser terrain. At 320 grams, our lightest tubeless rim is 27mm wide and designed for tires marked 27.5 or 650B. Armed against pinch flats with the patent-pending Wide Hookless Bead, the G27 is at home off-road and capable on tamer stretches of singletrack. Who It's For Those seeking the challenge of drop-bar riding over more technical terrain that is typically frequented by mountain bikes will benefit from the additional air volume, durability, and anti-flat performance benefits provided by the G27. If your path leads you to rough roads, single tracks, and multi-day bikepacking adventures, the G27 may be for you. Why We Made It There is a place between road and mountain that is open to discovery. Beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with contradicting challenges and demanding requirements are at odds with the bikes and products available today. We built the new G27 to thrive in this new environment because insights gained through building the world's best road and mountain bike rims told us that the perfect combination did not exist in our stable, or in our opinion, anywhere at all. The higher volume and lower pressures would demand MTB toughness and flat resistance, while big days and long miles would require the light weight and efficiency of a road machine. Above all, the combination of rough and rigid would require a wheel with the ride quality to make those long miles enjoyable and multi-day treks possible.

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.

What It Is The SES 3.4 AR is the embodiment of the modern disc brake-only road wheelset. Aerodynamically optimized for high-volume tires (28 - 32mm), lightweight for long days in the mountains, high volume for all roads, and arguably the most versatile wheelset ENVE has ever made. Science & Insight In 2016 we launched the SES 4.5 AR, a wheelset ahead of its time. Since then, road riders, frame manufacturers, and tire makers have all caught the high-volume vision which has propelled the one-of-its-kind 4.5 AR to be our most popular wheel in North America where the high-volume all-road movement has gained the most traction. As more bikes are created that can accommodate tire clearances up to 32mm, we saw the need to create a more versatile, climber-friendly SES AR wheelset, and the SES 3.4 AR was born. Points of Differentiation - Real-world aerodynamics, optimized around 28mm to 32mm tubeless tires - Wide, Hookless Bead Anti-Pinch Flat Technology - Disc brake-specific materials and construction - Low weight leader in category - Tubeless-only design

What It Is The SES 4.5 AR Disc is an uncompromising aero wheel designed specifically for disc brake-equipped bikes and large volume 28 – 30mm road tires. Who it's for Cyclists looking for more speed, comfort, and traction on all road surfaces will find the SES 4.5 AR Disc a game-changer. Why we made it The introduction of road frames with disc brakes and increased tire clearance has allowed us to take an unconventional approach to wheel design. The result is a wheel that brings new levels of confidence and performance to the road cycling experience. Full Details Rebellious, unconventional, and pioneering are words that describe the one-of-its-kind SES 4.5 AR Disc. Conceptualized for the cobbles of Paris-Roubaix through our partnership with Team Dimension Data, the SES 4.5 AR Disc was developed to deliver top-shelf aero performance, stability, and comfort for virtually any road surface. The SES 4.5 AR Disc borrows from ENVE's M Series carbon mountain wheel tubeless technology and features hookless beads. Hookless beads improve aerodynamic performance by aiding airflow from tire to rim as well as allow for the best tubeless tire performance possible. Like all Smart ENVE System aero wheels, the front and rear rims are specifically designed for the airflow seen at the front and back of the bike. As such, the front rim is shallower and wider to maximize stability in crosswinds, while the rear is deeper and narrower to aid in drag reduction. In addition to dissimilar geometries, the SES 4.5 AR Disc features a disc brake-specific construction that saves weight, improves strength, and creates an unprecedented ride quality.

What It Is The ultimate disc brake-specific, aerodynamic, lightweight road race wheelset. Who It's For The SES 5.6 Disc is optimized aerodynamically and structurally for disc use. Road cyclists and triathletes on disc brake bikes will benefit from the SES 5.6 Disc's reduced drag, lightweight design, and rim shape optimized for larger-volume road tires. Why We Made It Most "disc brake" wheelsets are simply repurposed rim brake wheels with disc hubs. The elimination of a braking surface opens up the realm of aerodynamic and structural possibilities. When you don't have to engineer a flat braking surface and manage high temperatures from braking, you can reduce the rim's weight, adjust shape for improved aerodynamics and provide better tubeless performance. Full Details Disc brake technology offers improved braking performance for amateur and professional road cyclists alike. Carbon fiber braking surfaces are a major design constraint that limits weight savings and rim design. By removing the constraints of a braking surface, we can completely rethink the shape of the rim. The SES 5.6 Disc features patented SES rim curvature, but has been further optimized for disc brakes. Additionally, the SES 5.6 Disc carbon fiber clinchers and tubulars are very lightweight, because the material used for rim brake heat management has been eliminated. This allows for a more structurally efficient and impact-resistant rim. Finally, the SES 5.6 Disc carbon clincher is road tubeless-compatible and can still be run with standard inner tubes and tires. Like the current generation SES carbon clinchers and tubulars, the 5.6 Disc has been aerodynamically optimized around 25mm tires.

What It Is The SES 5.6 is the evolution of the proven SES 4.5. By implementing the latest SES technologies, the SES 5.6 is not only faster than its predecessor, but also more stable and confidence-inspiring in challenging wind conditions. Other changes include tubeless tire compatibility for improved traction, rolling efficiency, and fewer flat tires. Who It's For Road racers and triathletes looking to maximize speed and efficiency through class-leading aerodynamics paired with rolling resistance-defying road tubeless technology. Why We Made It The SES 4.5 has been a staple in the Smart ENVE System family of wheels since its launch in 2014. Since then, nearly everything in road racing has changed; among them, the realization that more volume can equate to more speed and efficiency on the road. The SES 5.6 is road tubeless-compatible and embodies the spirit of the SES 4.5 by taking its position in the SES lineup as the best road racing wheelset on the market. While disc brakes are commonplace on the road, we acknowledge that they're not necessary or desired by everyone. For the rim brake rider looking for uncompromised braking performance, our textured full-carbon brake track features industry-leading heat resistance and uncontested stopping power and modulation in wet or dry weather conditions. By employing the latest Smart ENVE System aero technologies, the SES 5.6 is faster, more stable, and designed to seamlessly pair with modern road bikes to improve your performance and ride experience.

Making up about 50% of your total race time, the bike portion of a triathlon is where equipment choices can make the difference between first and fifth, and no other equipment choice will save you more time than a disc wheel. While traditionally-shaped disc wheels are faster than their spoked counterparts, the Roval 321 Disc for disc brakes turns conventional design on its head, creating the fastest wheel on the planet. Disc wheels often fall into two categories—a completely flat shape, with structure coming from carbon fiber and a honeycomb-foam filling, or a spoked wheel that's been faired with a carbon fiber cover. In our quest to break traditions, the 321 uses a single layer of 1k carbon fiber on each side of the wheel, and it all comes together at the brake track bridge. This kind of carbon fiber is rarely used in bicycle components due to its high manufacturing cost, but it offers a bevy of performance benefits. This coveted carbon is much lighter than other layups, like 3k and 12k, and it can only be laid by the most skilled of carbon fiber craftsmen. It's complicated, but the payout is worth it, as it delivers a supple ride and one of the lightest disc wheels available. And in the real world, this means that it'll spin-up quickly and reduce fatigue over the length of the course. Stiffness is often the “hot-topic” in the disc wheel world, but we think it’s an interesting conversation. It's long been thought that efficient power transfer and high stiffness are directly correlated, but through extensive field-testing, we've determined that this isn't the case at all. In fact, our initial disc was so stiff that, under power, it wouldn't flex with the frame and this caused brake rub. This wrongly creates the perception of a flexy wheel, when really, the wheel is actually too stiff. In order to solve the brake rub problem, we first designed our optimal aero shape and then worked on our internal stiffness targets to fit within what we consider to be a desirable frame stiffness. And while light overall weight was a development priority, our focus was aerodynamics. Through hours of Computational Fluid Dynamics (CFD) and testing in the Win Tunnel, we developed a never-before-seen shape that's optimized to work with a tire for on-bike airflow. What this translates to is an all-carbon disc wheel that, on the non-drive-side, has a shape that's as aerodynamic as our current understanding allows, and a drive-side shape that's as aerodynamic as the wheel-dish and derailleur clearance will allow for. To save every possible watt, we've also added CeramicSpeed bearings and DT Swiss 240 hub internals into our hub. Each 321 Disc wheel is also 2Bliss Ready right out of the box and comes with a padded wheel bag, quick-release, and tubeless valve stem. Designed for the most uncompromising athletes in the world, with engineering to match, the 321 Disc is the world's most advanced disc wheel for your race against the clock. - Rim Type: Full carbon clincher, 2Bliss Ready - Rim Material: Carbon - Braking Surface: Disc brake only - Rim Depth: Solid Disc - Rim Width: 19mm internal, 27.3mm external (at brake track) - Rear Hub: Roval Disc 142x12mm, CeramicSpeed bearings, DT Swiss 240 internals, 11-speed - Assembly Method: Handmade - Extras: Roval padded wheel bag, Roval tubeless valve, Roval valve pocket covers - Weight: 1015g

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 flick'able, 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. Whether you need a carbon wheelset to get you through an enduro stage or one to shred your local rock garden, the Traverse SL Fattie has you covered.
