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

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

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. The rear hub is adorned with DT Swiss's renowned 240 star ratchet internals. The wide, carbon rim provides a round tire profile and greater lateral stiffness for precise handling. This feathery, 1240-gram wheelset spins up with ease so you can bolt out of corners and breeze up the climbs. With your favorite tubular tires, these wheels roll as smooth as silk.

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 Disc, 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, take some aero guidance from the CLX 64, and keep all of the disc brake benefits that we've come to love if we were going to create what we like to call "the unicorn wheel." Why discs you ask? With our disc-specific rims, we ditch the brake track, making for a stronger, more impact-resistant rim. This way, you get a disc-specific carbon layup that optimizes stiffness, a weight as close to its rim-brake brethren as possible, and incredible brake modulation and power in all conditions. 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 best supported our svelte weight requirements, we opted to lace the rims to our Aero Flange (AF) hub, via 21 DT Swiss Aerolite spokes, which features the legendary CeramicSpeed bearings. This way you get a complete, superior wheel system—not just a quick rim. And at the end of the day, it all amounts to a 50mm-deep, 1415-gram clincher disc wheelset that's not only ~300 grams lighter than the competition’s similar depth wheel, but is also measurably faster in every conceivable test than each wheel in its category.
