THIS WHEELSET IS COVERED BY A LIFETIME WARRANTY Why We Make This We understand what makes wheels fast. The keys are fast bearings, power transfer, and a rim that absorbs road chatter and holds its line. When we began working with FusionFiber®, the revolutionary thermoplastic carbon fiber in our rims, its ability to eat road noise and stay planted suggested it could be part of a super high-performance wheel build. We make the ARD44 because we think it's the best a road wheel can be, and that's the idea, the kind of product, that makes us want to ride further, longer and faster. Why You Want It The ARD44 is designed for serious cyclists who want all-out speed on flats, climbs and through corners. It's an aero wheel that shines across a wide range of terrain, from smooth pavement to rough gravel roads. Built to surpass even the most rigorous industry standards, the ARD44 Wheelset is built around King's industry-leading R45D hub and an aero-profiled, 44mm deep FusionFiber® rim. The combination delivers unparalleled power transfer, speed, and stability. King's R45D hub serves as the perfect core for this wheelset, with their superior, house-made bearings, perfectly matched races, and single-piece axles. The R45D's flanges are optimized for lateral stiffness and durability. The final piece is Chris King's unparalleled RingDrive™ system, which maximizes engagement throughout the pedal stroke by providing 45 points of simultaneous engagement. King's reputation throughout the industry is built on bearings that wear in, not out coupled to RingDrive's™ high engagement super-efficient core. The ARD44's rim produces a stable, responsive, and nimble ride while reducing bodily fatigue and strain on the rider, due to the superior damping attributes of FusionFiber's® thermoplastic technology. It effectively minimizes unnecessary road feedback and vibrations, resulting in better traction and a smooth, comfortable ride that will keep riders fresher, and longer, and make the next day's ride easier too. - Aerodynamically tailored for 28mm-30mm tire - 25mm internal width and 30.5mm external width accommodate a broad range of tire sizes generally up to 47mm. - Hookless, tubeless rim design simplifies installation and maintenance while optimizing the interface between the tire and rim bed. - Lifetime warranty - Hubs Made in our Portland, OR factory - Rims Made in Utah - Hubs available in all current Chris King colors WHAT EXACTLY DO YOU MEAN WHEN YOU SAY "LIFETIME WARRANTY"? Lifetime warranty. You hear about it, but it can mean a lot of different things, especially when you get into the fine print. So, this is how it works with our new Chris King Fusion Fiber rims.

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless wheels are for dedicated cyclists who aspire to the latest in technology. They're for those who compete in races, against peers, or simply to conquer personal limits. - New Zipp graphics and cosmetic identity that scream speed - Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile - Lighter weight than its predecessor, making it nimble and fast - Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. - Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road - 40mm rim depth makes a light and aero wheel in every situation - Ships with 12mm end caps - Center Lock rotor interface (lockring included)

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
