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. The SES 4.5 rounds out the Smart ENVE System wheel line as a true mid-depth everyday cycling race wheelset. Additionally, the SES 4.5 features a refined shape and construction that yields better acceleration, cornering, impact resistance, and weight savings.

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.

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

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. It is extremely light yet stiff, resistant to shock and perfectly balanced: a versatile wheel for any kind of route. - Use of resins and materials that guarantee superior finish and good UV resistance - Designed specifically for disc brake systems - Lightweight uphill thanks to its 35mm rim - Smooth and safe downhill thanks to its USB bearings - The layers of carbon are hand positioned to ensure the perfect equilibrium of weight and performance - Monolithic aluminum hubs optimize disc braking torque - Weight: 1483 grams

What It Is The G23 is the definition of a true gravel wheelset. At 330 grams, ENVE's lightest 700c tubeless rim accelerates quickly and ascends with ease. Armed against pinch flats with the patent-pending Wide Hookless Bead, the G23 is tough and relentless on road, path, or trail. The G23 is a 700c tubeless carbon clincher wheelset with a generous 23mm internal width, specifically conceived to meet the performance and ride quality demands of serious mixed-surface cyclists. Who It's For Created for those seeking to discover new experiences, new terrain, and new challenges. Built to reflect the versatility of today's gravel and mixed surface riders, these wheels will excite ambitious, daring, and indomitable riders everywhere. If your path leads to classics like Dirty Kanza, Landrun, Crusher in the Tushar, or a new wave of events like Grinduro or Lost and Found, the G23 is your wheel. 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 G23 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 lightweight 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.

This wheel is the future of gravity riding and racing. It's ride-optimized, incredibly strong, and debuts the most effective and lightest anti-flat system on the market (ENVE's patent-pending Protective Rim Strip). These wheels will give downhill-oriented riders a new freedom to set their tire pressure for cornering and rock garden stability without sacrificing their confidence to smash track speeds. Who It's For Gravity junkies, Enduro racers, and hard-charging trail riders will find enlightenment riding the M7 Series. A completely new shape and design that massively reduces the risk of pinch flatting and/or damaging the carbon, the M7 Series provides the confidence to ride without limitations. Why We Made It Enduro runs on two things – Confidence and Control. Nothing ruins a good shred fest like a flat tire or broken rim, and nothing spooks you on a dusty trail like an unexpected drift. With this in mind, we have been hard at work over the past 2 years to develop a carbon wheel system that will allow ourselves, athletes, and most importantly – you – to go "full-send" without compromising the ride experience by running high tire pressures, DH tires, and heavy pinch flat reduction inserts. Building upon the platform of the M7 Series' predecessor the M70, we re-profiled the rim to mate up with modern tires and to absorb trail vibrations and chatter. However, just fitting tires is not enough. We know that riders also want the freedom to run lower pressure and that doing so can introduce flat tires and damaged rims. The ENVE solution is a new rim shape paired with ENVE's patent-pending, energy-absorbing Protective Rim Strip. With this technology, riders can skip the inserts and run the tires and pressures they want. Amazingly, we've managed to keep the weight neutral and improve impact resistance too.

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 Disc 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.

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.

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

The tempo is only getting faster as your small group of survivors barrels closer to the line. Leaning into a hard right-hander, the 24.4mm-wide rims feel solid, dependable, and awesome. Victory is seconds away, but a challenger surges ahead on your left. Drop a gear, feel the engagement of the DT Swiss hub internals and go. The result? Ride the Roval Rapide CLX 60 Wheelset and find out.

The CLX 64 Track Tubular was brought to life under the Allez Allez team at the 2016 Red Hook Crit. Along these lines, you get all of the unrivaled aero performance of the CLX 64, albeit with DT Swiss track hubs and Aerolite spokes, for a stiff, smooth, and most importantly, fast ride on the boards. One of the first questions we get about the CLX 64 is, “Why 64mm instead of 65mm?” To put it simply, it's because 64mm tested faster than 65mm. One millimeter—that's how deep our testing goes. Having an in-house wind tunnel allows us to run every possible variation, and after two-years of development, 80 variations in rim design, and nearly 300 hours of Win Tunnel testing time studying tire and frame interactions, we found 64mm to be the fastest iteration for normal riding conditions. In fact, it's even faster than the 80-plus-millimeter-deep wheels they were tested against. Being able to use a shape that’s nearly 20mm shallower than the competition, yet just as low in drag, makes for a wheel that has drastically less side force and steering torque. This translates to less buffeting and more confidence in even the gustiest winds. Another positive of a shallower rim depth is the reduction in weight that follows using less material. Many deep carbon wheels feel “slow” due to their high inertia value. What's that? Inertia is the amount of force it takes to accelerate or decelerate, and wheels that are built around heavier rims lack the liveliness that many riders crave. Being over a half-a-pound lighter than the other wheels in its aero category, the CLX 64 accelerates, decelerates, and changes direction with less effort.

Whatever road you choose, the ERC 1100 DICUT delivers the best performance. The benchmark Aero+ concept developed with DT's partner SWISS SIDE generates maximum speed and unparalleled handling characteristics. The guts of this outstanding wheel are its innovative components, being assembled with regard on every small detail. These wheels leave you with no excuses and give you even more reasons to get out and ride — wherever the road may take you.

What you're looking at here is gravity's nemesis: Roval's Control SL 29 Wheelset 148. At 1,330 grams, you'll climb XC courses with ease on these lightweight, hookless-bead, carbon hoops. They're built to withstand grunting up climbs, descending with abandon, and blasting in and out of corners with Specialized carbon rims, DT Swiss spokes, and DT Swiss's legendary 240 rear hub internals. The Boost spacing offers increased width on the front and rear hub flanges, and in turn, increased frame and fork clearance and stiffness. This combines to deliver a more durable wheel system at a minor weight penalty. Plus, these sweet race-ready wheels are tubeless-compatible so you are ready for anything that the trail throws at you.

The punchers wheel: The medium-profile aero rim, partly bladed spokes, and lightweight build make it easy to flow with the pack and launch your punchy attack when the time is right. Even in the harshest weather conditions the ARC 1100 DICUT 48 will lead you rapidly to the line. Combining carbon know-how with SWISS SIDEs leading aero knowledge, this wheel epitomizes lightweight and low drag. The aero hub design, featuring straight pull nail-head spokes and SINC ceramic bearings, make it stiff and smooth rolling — just right to surprise the lead-out train.

Aero meets All-around: The ARC 1100 DICUT 62 is ridden by DT Swiss athletes in long distance triathlons, as well as in flat stages of the Tour de France. Adding to it's versatility is the Aero+ concept: It is the category leader when it comes to low drag numbers but at the same time it is easy to handle in every wind situation. Hubs equipped with SINC ceramic bearings and ultra-lightweight components throughout are there to make you roll smooth and fast, no matter if you're fighting against the wind on your time trial bike or trying to escape the bunch on the final meters to the line.

If going flat out fast is what you want, then this wheelset has all the details covered. DT's top triathletes choose the ARC 1100 DICUT 80 when it's race day. It's developed in partnership with aerodynamics specialists SWISS SIDE and equipped with SINC ceramic bearings to get up to speed and stay there. Supporting the complete system of the rider and bike with minimal drag and unparalleled handling under all conditions, riding fast is guaranteed. Finally the precision wheel build with high and even spoke tension gives you the reliability to dominate all of the 180 km.
