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 fibre and a honeycomb-foam filling or a spoked wheel that's been faired with a carbon fibre cover. In our quest to break traditions the 321 uses a single layer of 1k carbon fibre on each side of the wheel and it all comes together at the brake track bridge. This kind of carbon fibre 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 fibre craftsmen. It's complicated but the pay-out 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.

Feel your bike come alive on the open road with the new Alpinist CLX II—the lightest best-handling clincher wheels we have ever made. Hyper-responsive acceleration magic in the corners sublime over rough roads all elevated with the performance of a tubeless system. There’s no room for a single excess gram whether you’re chasing summits or ride quality because perfection is only achieved when there is nothing left to take away. It takes more than a lightweight rim to deliver the incredible reactivity and handling of the tubeless Alpinist CLX II. The wheelset is designed as a system with our engineers controlling and testing every part of that system—hubs rims spokes lacing—and developing it hand-in-hand with Specialized Tubeless tires. The result is a 1250-gram tubeless wheelset with otherworldly ride quality. The Alpinist CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi if that’s your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible. Our all-new LFD hubs are the spinning heart of the Alpinist CLX II. We carved 50 grams out of the previous Alpinist CLX hub with new low-profile hub bodies and machined rotor mounts. Inside DT Swiss EXP internals and SINC ceramic bearings deliver silky-smooth efficiency and outstanding durability.

Since 2020 Rapide CLX wheels have won more races on the World Tour than any other wheels and we just made them faster. Meet the new Rapide CLX II. Combining the aerodynamics of a deep-section TT wheel with the light weight of a shallower climbing wheel and mixing in the superior efficiency and sublime handling of a tubeless system—the Rapide CLX II delivers maximum speed for real-world riding. We developed distinctly different shapes for the Rapide CLX II front and rear rims. The result is a wheelset that catches less drag than most 65mm wheelsets and brings a dramatic 25% improvement in stability over 50mm rims in wind gusts. The Rapide CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi if that’s your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible. Our AeroFlange hubs are aerodynamically optimized with wide bracing angles for increased strength and reduced spoke weight. They also benefit from the reduced weight and increased strength of ceramic SINC bearings and the legendary durability of DT Swiss’ EXP freehub internals.

Following directly in the tire tracks of the Terra CLX the new Terra CL utilizes the same super light incredibly tough rim as our flagship wheel. It’s a hook bead 33mm deep carbon fiber rim with a 25mm inner width that plays well with tubeless setup and allows you to mount tires anywhere from 28mm to 47mm wide at whatever pressure you feel like running. In a nod to accessibility durability and real-world serviceability we opted to use ultra-dependable DT Swiss 350 hubs and lace them to the rims with DT Swiss Competition Straightpull spokes.
