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. - Rim: Rapide CLX Carbon Clincher, 700c, Disc Brake, Tubeless Rim Details: 51mm Depth, 35mm External Width, 21mm Internal Width - Hub: Roval Aero Hub (AFD01/AFD02R) Center Lock, DT Swiss 180 Ratchet EXP 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

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 LightAF 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. - Rim: Alpinist CLX Carbon Clincher, 700c, Disc Brake, Tubeless - Rim Details: 33mm Depth, 27mm External Width, 21mm Internal Width - Hub: Roval Light Hub (LFD13/LF14R) Center Lock, DT Swiss 180 Ratchet EXP 36t internals (10 degs), 100x12mm & 142x12mm, Shim.

When we set out to create a wheelset built purely for speed, we wanted to make it more than just fast. Not that being fast wasn't a priority, but we were tired of wheels that only performed well in a straight line. In the end, we developed the CLX 64, the fastest wheel that we've ever tested. Not only is it the fastest in the tunnel, but its prestige has been verified with Gold Medals in the men's road race, time trial, and team time trial at the 2016 UCI World Championships. 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 simply 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 studying tire and frame interactions in the Win Tunnel, 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. The rim is not the only component of the CLX 64 that contributes to its aero prowess though, in order to create the fastest wheels, we focused on the wheels as a system, not just a rim with "other parts," and our Aero Flange (AF) hubs play a significant role. Designed completely in the Win Tunnel, our AF hubs feature an incredibly small frontal aero, without sacrificing stiffness, making them aerodynamically efficient. Taking the advantage a step further, these wheels were developed to work in harmony with modern-width 24C tires. The 21mm internal rim width spreads the tire out, in this case to 26C, making it seamlessly meet the rim. Not only does this create a system with low aerodynamic drag, but one that has exceptionally low rolling resistance and inspiring grip in the corners. And to make sure we checked all of the feature boxes, we also made the rim tubeless-ready. To top off the multitude of performance features of the rim, we chose the highest quality build components to pair the CLX 64 front with. Starting with DT Swiss Aerolite bladed spokes, which test faster than their round counterparts in the Win Tunnel, we hand-laced the 64 rim to our AF hubs that house CeramicSpeed's legendary bearings. Why hand-built? Machines make mistakes and mistakes aren't something we're ok with, so we have real people lace each wheel by hand. - Assembly Method: Hand-built - Brake Track Height: 12mm - Braking Surface: Carbon fiber - Extras: Roval padded wheelbag, Roval steel quick-release, Roval tubeless plugs and tubeless valve, SwissStop Black Prince brake pads - Front Hub: Roval AF1, CeramicSpeed bearings - Nipple Type: DT Swiss Pro Lock hexagonal - Rim Depth: 64mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 20.7mm internal, 29.9mm external - Spoke Count: 16 - Spoke Pattern: Radial - Spoke Type: DT Swiss Aerolite T-head - Weight: 695g

Races, training, group rides, gran fondos—Profile’s 58/Twenty Four Full Carbon Clinchers will be your new secret weapon. Their engineers used fluid dynamic modeling and wind tunnel testing to create a super slippery 58mm-deep by 24.5mm-wide rim for maximum free speed and slicing right through head and cross winds. Adding mph are the Sapim CX-Ray bladed spokes, which have locking nipples so they stay tight. These wing-like wheels save you massive energy on the flats and they're also light enough to rocket you up the climbs. Plus, Profile's careful hand assembly and advanced carbon layup mean rock-solid stiffness for outstanding power transfer. And, because sometimes you just have to hit the brakes, Profile includes high-tech carbon wrapping and a heat-resistant resin in its rims, plus carbon-compatible brake pads come with the wheels so you'll have more stopping power than ever. Upgrade to the 58/Twenty Fours and get ready to become a better rider.

There are no compromises on race day, and Profile Design knew that when they designed their 58/TwentyFour tubular wheels. The 58mm-deep rim, 24.5mm rim width, and super stiff carbin layup provide uncompromising go-fast performance. And, the aero shape of the rim slips easily through the breeze, increasing your efficiency and speed. Match these rims up with your favorite tubular tires (sold separately) and experience a ride that clinchers just can't offer, with high-traction cornering and a supple road feel you need to ride to believe. The hubs feature sealed bearings for high-mileage durability and the freehub body is Shimano/SRAM 9, 10, and 11-speed compatible so you can use the drivetrain of your choice.
