Roadies all drool over carbon wheels, but the price tag often puts them out of reach. The new C 38 Disc wheels break down this barrier while bringing reliable, high performance carbon road wheels to the masses. With the C 38, we developed an all-new, lightweight, and durable carbon rim with the modern features that savvy riders demand, and then we paired it with trusty DT Swiss components, like DT 350 rear hub internals and Competition spokes, for a build that ticks all the boxes on your wish list. The new C 38s are the perfect depth (38mm), too, so they'll feel at home on everything from gravel bikes, to aero bikes, and everything in between. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval tubeless tape and tubeless valves - Front Hub: DT Swiss 350 Disc for Roval, 100x12mm, Center Lock - Front Spoke Pattern: Two-cross/Radial - Nipple Type: DT Swiss Pro Lock Brass hexagonal - Rear Hub: DT Swiss 350 Disc for Roval, 142x12mm, Center Lock, 11-speed - Rear Spoke Pattern: Two-cross/Two-cross - Rim Depth: 38mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 21mm internal, 26.6mm external - Spoke Count: 24 front, 24 rear - Spoke Type: DT Swiss Competition Race J-bend - Total Wheelset Weight: 1,560g

After designing the CLX 50s, we realized that an affordable, race-worthy carbon wheelset was nowhere to be found, until the CL 50 Disc was developed, that is. We paired our quiver-killing CLX 50 Disc rim with DT Swiss Competition round spokes, our Aero Flange Disc hubs with DT Swiss 350 internals, and steel bearings to deliver you an exceptional wheelset at a more than accessible price. Why disc you ask? With our disc-specific rims, you not only ditch the brake track, but you get a stronger, more impact-resistant rim. This comes at the hands of a disc-specific carbon layup that optimizes stiffness and keeps weight as close to its rim-brake brethren as possible. And all the while, you get incredible brake modulation and power in all conditions. Sharing rims with the CLX 50s, the CL 50s feature many of the benefits as their higher-end siblings. Even though the CL 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 CL 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. Now it was time for final testing validation. The result? A 50mm-deep, 1515-gram clincher wheelset that's race-ready and wallet-friendly. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval steel quick-releases, Roval tubeless plugs and valves, Front quick-release, 12mm endcaps, Rear quick-release, 142x12 thru-axle endcaps - Front Hub: Roval AFD1, Center Lock, sealed cartridge bearings, quick-release or 12mm thru-axle end cap - Front Spoke Pattern: Two-cross/Radial (2:1) - Nipple Type: DT Swiss Pro LockBrass hexagonal - Rear Hub: Roval AFD2, Center Lock, sealed cartridge bearings, DT Swiss 350 internals, 11-speed, quick-release or 142x12mm thru-axle end cap - Rear Spoke Pattern: One-cross/Two-cross (2:1) - Rim Depth: 50mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Width: 20.7mm internal, 29.4mm external - Spoke Count: 21 front, 24 rear - Spoke Type: DT Swiss Competition Race T-head - Total Wheelset Weight: 1,515g

The Roval SLX 24 Disc is a no nonsense wheelset. At only around 1515 grams, it's designed for light overall weight, but this doesn't mean that it sacrifices anything to strength or durability.

When we set out to create a lightweight tubular disc wheel, we didn't want it to be "just another climbing wheel." We wanted to provide the lightest disc wheelset available with the aerodynamic attributes of something twice its depth. It was a tall order, but in the end, our CLX 32 Tubular Disc not only not only delivers on this in spades, but it also provides incredible brake modulation and power in all conditions, increased impact resistance, and a disc-specific carbon layup that increases strength while decreasing weight. Our design process started with a low overall weight at the forefront, as we knew what weight we could hit with the information and technology we had available. With that weight in mind, we then turned our focus to aerodynamics and began an iterative process of designing and testing over 150 individual rims to find the optimal shape. These innumerable Computational Fluid Dynamics (CFD) models, Win Tunnel hours, and shots of espresso left us with a 32mm-deep shape that boasts more logged wind tunnel time than any other wheel in its category. Once we found the most aerodynamic shape, at the 32-millimter depth, we came back to the weight focus and proceeded to experiment with over 40 different layup methods to reach our desired weight. And this made the CLX 32 lighter and faster than every other competitor in the lightweight wheel category. For this CLX 32, we mated the rim to our Aero Flange (AF) series hub with DT Swiss Aero spokes to create the best overall system. This results in a 550-gram, front wheel with an extremely low inertia value. In cycling, inertia relates to the amount of force it takes to accelerate or decelerate, so wheels that are built with lightweight rims, like the CLX 32, result in a lower inertia value that creates a lively wheel that allows you to accelerate, decelerate, and change direction with less effort. But why so wide? Well, additional width does three primary things for a rim, it provides additional structural strength, it allows for a clean rim and tire interface when using wide tires (resulting in enhanced aerodynamics and faster rolling properties), and it better supports the tire in hard cornering. This boosts both predictable grip and confidence when things get twisty on the descents. Each front wheel also employs the legendary CeramicSpeed bearings and comes with our padded wheelbag, quick-release, tubeless plugs, tubeless valve, and SwissStop Black Prince brake pads. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval padded wheelbag, Roval steel quick-release, 12mm thru-axle, quick-release end caps - Front Hub: Roval AFD1, Center Lock, CeramicSpeed bearings, quick-release or 12mm thru-axle end cap - Nipple Type: DT Swiss Pro Lock hexagonal - Rim Depth: 32mm - Rim Material: Carbon - Rim Type: Carbon tubular - Rim Width: 27.1mm external - Spoke Count: 21 - Spoke Pattern: Two-cross/Radial (2:1) - Spoke Type: DT Swiss Aerolite (L)/Aerocomp (R) T-head - Weight: 550g

The Roval CLX 32 Tubular wheels are some of the lightest carbon wheels ever made, but this doesn't come at the expense of fundamental performance. Instead, painstaking engineering and lab testing helped them achieve a 490-gram front and 665-gram rear wheel that's tough enough for cyclocross racing, yet light enough for the demands of a GC climber. The low inertia and ample stiffness help the wheel accelerate and change direction on a dime. We didn't skimp on aerodynamic benefits either, despite this wheel's low rim profile. The CLX 32 was engineered in CFD around a 26mm-wide tire shape, and honed in Roval's very own Win Tunnel, in order to be as aerodynamic as some rims almost twice its depth. Meanwhile, Roval aero hubs and CeramicSpeed bearings complete the fast-engaging ensemble. Truly, the CLX 32 ushers in a new era of lightweight performance road wheels.

Slice through the wind on Roval's Rapide CLX 40 Wheelset. They feature 40mm-tall aero carbon rims, and DT Swiss Revolution straight-pull spokes laced to sealed ceramic cartridge bearings Roval hubs.

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 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 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.
