Zipp's 303 S Tubeless Disc Brake wheelset provides today's cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. - Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. The result is a larger contact patch for increased grip and confident cornering, descending, and handling in wet conditions. - Lower tire pressures and larger volume provides a compliant ride with fewer vibrations. - Significant watt savings when running larger tires at lower pressure. - Wide, hookless rims create a seamless transition to the tire, reducing drag. - Fastest with 28mm, but fits wide gravel tires as well - New Zipp graphics and cosmetic identity that scream speed

The Tactic is a great all-round and training wheelset with 23mm-wide lightweight alloy rim and straight-pull spokes for direct response and improved tire performance. The sleeved-joint rims are 26mm deep for improved stiffness and better acceleration. The Tactic rims utilize Vittoria's Speedlock design for easy tubeless setup and usage.

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

When we set out to create a lightweight tubular disc wheel, we didn't want it to be "just another climbing wheel." We wanted to provide the lightest disc wheelset available with the aerodynamic attributes of something twice its depth. It was a tall order, but in the end, our CLX 32 Tubular Disc not only not only delivers on this in spades, but it also provides incredible brake modulation and power in all conditions, increased impact resistance, and a disc-specific carbon layup that increases strength while decreasing weight. Our design process started with a low overall weight at the forefront, as we knew what weight we could hit with the information and technology we had available. With that weight in mind, we then turned our focus to aerodynamics and began an iterative process of designing and testing over 150 individual rims to find the optimal shape. These innumerable Computational Fluid Dynamics (CFD) models, Win Tunnel hours, and shots of espresso left us with a 32mm-deep shape that boasts more logged wind tunnel time than any other wheel in its category. Once we found the most aerodynamic shape, at the 32-millimter depth, we came back to the weight focus and proceeded to experiment with over 40 different layup methods to reach our desired weight. And this made the CLX 32 lighter and faster than every other competitor in the lightweight wheel category. For this CLX 32, we mated the rim to our Aero Flange (AF) series hub with DT Swiss Aero spokes to create the best overall system. This results in a 550-gram, front wheel with an extremely low inertia value. In cycling, inertia relates to the amount of force it takes to accelerate or decelerate, so wheels that are built with lightweight rims, like the CLX 32, result in a lower inertia value that creates a lively wheel that allows you to accelerate, decelerate, and change direction with less effort. But why so wide? Well, additional width does three primary things for a rim, it provides additional structural strength, it allows for a clean rim and tire interface when using wide tires (resulting in enhanced aerodynamics and faster rolling properties), and it better supports the tire in hard cornering. This boosts both predictable grip and confidence when things get twisty on the descents. Each front wheel also employs the legendary CeramicSpeed bearings and comes with our padded wheelbag, quick-release, tubeless plugs, tubeless valve, and SwissStop Black Prince brake pads. - Assembly Method: Hand-built - Braking Surface: Disc brake only - Extras: Roval padded wheelbag, Roval steel quick-release, 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: 32mm - Rim Material: Carbon - Rim Type: Carbon tubular - Rim Width: 27.1mm external - Spoke Count: 21 - Spoke Pattern: Two-cross/Radial (2:1) - Spoke Type: DT Swiss Aerolite (L)/Aerocomp (R) T-head - Weight: 550g

The Roval CLX 32 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 them achieve a 490-gram front and 665-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 Roval's very own Win Tunnel, in order to be as aerodynamic as some rims almost twice its depth. Meanwhile, Roval aero hubs and CeramicSpeed bearings complete the fast-engaging ensemble. Truly, the CLX 32 ushers in a new era of lightweight performance road wheels.
