700c, 27-Inch & 650c

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.

Roadies all drool over carbon wheels, but the price tag often puts them out of reach. The new C 38 Disc wheels break down this barrier while bringing reliable, high performance carbon road wheels to the masses. With the C 38, we developed an all-new, lightweight, and durable carbon rim with the modern features that savvy riders demand, and then we paired it with trusty DT Swiss components, like DT 350 rear hub internals and Competition spokes, for a build that ticks all the boxes on your wish list. The new C 38s are the perfect depth (38mm), too, so they'll feel at home on everything from gravel bikes, to aero bikes, and everything in between. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval tubeless tape and tubeless valves - Front Hub: DT Swiss 350 Disc for Roval, 100x12mm, Center Lock - Front Spoke Pattern: Two-cross/Radial - Nipple Type: DT Swiss Pro Lock Brass hexagonal - Rear Hub: DT Swiss 350 Disc for Roval, 142x12mm, Center Lock, 11-speed - Rear Spoke Pattern: Two-cross/Two-cross - Rim Depth: 38mm - Rim Material: Carbon - Rim Type: Carbon clincher, 2Bliss Ready - Rim Width: 21mm internal, 26.6mm external - Spoke Count: 24 front, 24 rear - Spoke Type: DT Swiss Competition Race J-bend - Total Wheelset Weight: 1,560g

Equip yourself with the wheel that carried Tony Martin to a World Championship and reach the pinnacle of your own potential. Zipp’s Super-9 Carbon Clincher Disc underwent extensive fluid dynamic modeling, wind-tunnel testing, and relentless refinement so you can enjoy no-holds-barred aero domination. With a variance in width of just a single centimeter from rim to hub, the Super-9 is almost invisible to the wind. Plus the wide rim creates a virtually seamless integration with the tire, increasing aerodynamics and allowing wider tires run at a lower pressure. This diminishes rolling resistance, increases rider comfort, and reduces the chance of pinch flatting.

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.

Riders known for being hard on their wheels, for not avoiding potholes, and for out sprinting people in full pro kit while on their way to do the groceries should take a close look at the ER 1600 SPLINE 32. A high-end welded alloy rim with a huge cross section laced to wide aero spokes leave you with nothing left to desire. And don't be fooled by the classy looks and a silky smooth Ratchet System hub, because the ER 1600 SPLINE 32 really is all about hard riding and reacting to power coming from the strongest of calves.

Following the success of the 808 NSW, which was ridden to victory at the Pro Men’s Ironman World Championships and the Elite Women’s UCI Team Time Trial World Championships, Zipp is proud to launch their second wheelset in the NSW Series, the Zipp 404 NSW Carbon Clincher. Zipp's advanced development engineers in their top-secret lab, known as The Nest, have delivered a wheelset with improved braking performance, exceptional aerodynamic efficiency, and unparalleled crosswind stability with the most popular and best-selling rim depth. Like the 808 NSW, the 404 NSW also makes use of a Cognition hubset for increased durability and exceptionally low freehub drag. No matter where you ride, the 404 NSW is engineered to make that ride faster. With a rim depth of 58mm, the 404 NSW is designed as a do-everything wheelset that is adept at climbing and maintaining speed on the flats; a wheel strong enough to handle the Spring Classics, but light enough to inspire sprints out of corners. With its advanced aerodynamics, developed using 42 different CFD (Computational Fluid Dynamics) concept studies and months in the wind tunnel, the 404 NSW’s unrivaled crosswind stability saves watts that would have been spent keeping the bike straight, and provides unequivocal confidence for high speed descending. When it comes time to slow for a corner, the NSW-exclusive Showstopper brake track stands ready to deliver the best modulation and shortest stopping distances available, regardless of weather conditions or the length of the descent. Simply put, the 404 NSW represents the cutting-edge of carbon clincher wheel technology delivered straight from The Nest, where Zipp’s advanced development engineers design the world’s fastest wheels.

Featuring a lightweight rim and strong bladed spokes, it's a wheel that marries good climbing abilities with a precision ride.

What It Is The ultimate everyday carbon fiber cycling wheelset and choice of Team Dimension Data. Who it's for Road cyclists and triathletes looking to minimize the trade-off between aerodynamics, lightweight, and stability. Why we made it Because from the moment the first prototypes made the rounds at ENVE, it's been the house favorite. The SES 4.5 rounds out the Smart ENVE System wheel line as a true mid-depth everyday cycling race wheelset. Additionally, the SES 4.5 features a refined shape and construction that yields better acceleration, cornering, impact resistance, and weight savings.

At the helm of taking traction, stability, speed, and stiffness to new heights stands the Roval Traverse Fattie 38 650b wheels with 110mm front and 148mm rear hub spacing. And while their Boost-spacing axle widths give the frame and fork clearance and stiffness that results in a stiffer, stronger, and more durable system at a minor weight penalty, what turns them into descending machines is the 38mm internal rim width. The reason behind this is relatively simple: aside from the lightweight, ultra-rugged E5 alloy construction, the combination of the revolutionary width with wider hub flanges equates to an increase in plus-sized tire volume for more suppleness in the ride quality. Not only this, but the ample width also better supports the tire, meaning that you'll experience less "burping" when riding tubeless, as well as a drastic increase in traction. These aren't just a one-trick pony, however. At the front hub, you'll get a 15x110mm thru-axle (end cap options included), and at the rear, the 148mm hub features DT Swiss internals for lightning-fast engagement and acceleration.

What It Is The SES 3.4 AR is the embodiment of the modern disc brake-only road wheelset. Aerodynamically optimized for high-volume tires (28 - 32mm), lightweight for long days in the mountains, high volume for all roads, and arguably the most versatile wheelset ENVE has ever made. Science & Insight In 2016 we launched the SES 4.5 AR, a wheelset ahead of its time. Since then, road riders, frame manufacturers, and tire makers have all caught the high-volume vision which has propelled the one-of-its-kind 4.5 AR to be our most popular wheel in North America where the high-volume all-road movement has gained the most traction. As more bikes are created that can accommodate tire clearances up to 32mm, we saw the need to create a more versatile, climber-friendly SES AR wheelset, and the SES 3.4 AR was born. Points of Differentiation - Real-world aerodynamics, optimized around 28mm to 32mm tubeless tires - Wide, Hookless Bead Anti-Pinch Flat Technology - Disc brake-specific materials and construction - Low weight leader in category - Tubeless-only design

Why We Made It There is a place between road and mountain that is open to discovery. Beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with contradicting challenges and demanding requirements are at odds with the bikes and products available today. We built the new G23 to thrive in this new environment, because insights gained through building the world's best road and mountain bike rims told us that the perfect combination did not exist in our stable, or in our opinion, anywhere at all. The higher volume and lower pressures would demand MTB toughness and flat resistance, while big days and long miles would require the lightweight and efficiency of a road machine. Above all, the combination of rough and rigid would require a wheel with the ride quality to make those long miles enjoyable and multi-day treks possible.

What It Is The fastest carbon fiber Smart ENVE System aero wheel yet. Who It's For Experienced triathletes and road racers seeking maximum aero performance and stability.
