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. 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 Disc, the fastest wheel that we've ever tested with all of the performance benefits of disc brakes we have come to love. This iteration has a more impact-resistant rim, a disc-specific carbon layup that optimizes stiffness and weight, and incredible brake modulation and power in all conditions. 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-lace the 64 rim to our AFD 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 - Braking Surface: Disc brake only - Extras: Roval padded wheelbag, Roval steel quick-release, Roval tubeless plugs and tubeless valve,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: 64mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 20.7mm internal, 29.9mm external - Spoke Count: 21 - Spoke Pattern: Two-cross/Radial (2:1) - Spoke Type: DT Swiss Aerolite T-head - Weight: 735g

Performance Upgrade Made Easy The C38 brings carbon fiber high performance to the real world. It's a versatile all-rounder equally at home crushing gravel washboards and summiting alpine passes. Optimized for use with modern wide tires, providing the right amount of sidewall support to facilitate surefooted handling in all conditions, the C38 wheelset is a great handling, lively climbing, robust all-road performer that also aerodynamically outperforms many deeper, aero-specific rims that cost twice as much. Carbon wheels are a true performance upgrade to any bike, but too often the price tag puts them out of reach. The Rapide C38 shatters that barrier and brings a class-leading Roval carbon rim and DT Swiss reliability together to provide riders with the best performance carbon wheel per dollar.

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.
