700c, 27-Inch & 650c

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

After designing the CLX 50s, we realized that an affordable, race-worthy carbon wheelset was nowhere to be found—until the CL 50 was developed, that is. We paired our quiver-killing CLX 50 rim with DT Swiss Competition round spokes, our Aero Flange hubs with DT Swiss 350 internals, and steel bearings to deliver you an exceptional wheelset at a more than accessible price. 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, 1465-gram clincher wheelset that's race-ready and wallet-friendly. - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Material: Carbon - Braking Surface: Carbon Fiber - Brake Track Height: 12mm - Rim Depth: 50mm - Rim Width: 20.7mm internal, 29.4mm external - Front Spoke Pattern: Radial - Rear Spoke Pattern: Radial/Two-cross (2:1) - Spoke Count: 16 front, 21 rear - Spoke Type: DT Swiss Competition Race T-head - Nipple Type: DT Swiss Pro LockBrass hexagonal - Front Hub: Roval AF1, sealed cartridge bearings - Rear Hub: Roval AF1, sealed cartridge bearings, DT Swiss 350 internals, 11-speed - Assembly Method: Hand-built - Extras: Roval steel quick-releases, Roval tubeless plugs and valves, SwissStop Black Prince brake pads

Engineered for light weight without sacrificing durability, the Roval SLX 24 is a no nonsense wheelset. The 20mm wide, tubeless ready, alloy rims provide an optimal tire profile to enhance confidence and feel on the road. Roval aero hubs with DT 350 star-rachet internals round out the package to create a light, stiff, and reliable wheelset. Tipping the scales at only 1460 grams, this wheelset is equally at home in a hilly road race or logging big miles training in the off-season.

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. Instead, its 20mm-wide alloy rims work to bolster the aforementioned characteristics, while also providing the optimal tire profile in order to enhance both confidence and feel on the road. Meanwhile, the rims have been built to Roval aero hubs that feature fast-engaging DT 350 star-ratchet internals at the rear. Add it all up, and you get a wheelset that checks all of the boxes for daily training and CX racing—lightweight, stiff, and incredibly reliable.

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.

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. The tubular version of the CLX 50 also features a rim design that differs from the clincher version, in order to be aerodynamically optimized for tubular tires. And to prove our concepts, 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 this rear rim, 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, 1230-gram tubular wheelset that's not only ~ 275 grams lighter than the competition’s similar depth wheels, but is also measurably faster in every conceivable test than each wheel in its category.

The Roval CLX 32 Disc 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 Roval achieve a 550 gram front and 680-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 Specialized's very own Win Tunnel, in order to be as aerodynamic as some rims almost twice its depth. Meanwhile, a disc-first engineered design, Roval aero hubs, fitted with DT 240 star-ratchet internals, and CeramicSpeed bearings complete the fast engaging ensemble. Truly, the CLX 32 ushers in a new era of lightweight performance road wheels.
