The 404’s heritage as Zipp’s icon of speed extends back decades, and its future is even brighter. At 58mm deep, the 404 Firecrest Tubeless is ideal for road races, time trial and triathlon, and gran fondos. The wheelset’s 23mm internal width is perfect for running wider tubeless tires at reduced air pressure. That is a vital component of Total System Efficiency, or TSE, an approach to speed on ever-changing roads and riding conditions. Specifically, TSE focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses.

ZIPP 303 Firecrest 650b Tubeless Disc-Brake Front WheelThe definition of road cycling now includes gravel and dirt in addition to pavement. Simultaneously, bikes are evolving to meet the requirements of smaller riders. Zipp's 303 Firecrest 650b Tubeless Disc-Brake wheel was created to fulfil these needs. The smaller rim provides room within frames and forks for big-volume tyres, delivering improved comfort, compliance and cornering performance on the most challenging terrain. A 45mm rim profile reduces wind resistance, rolling resistance and weight but benefits from a wider internal width for enhanced performance and ride quality on almost every surface imaginable. ABLC (AERODYNAMIC BOUNDARY LAYER CONTROL)ABLC refers to the patented and instantly recognisable dimpled pattern found on all of Zipp's carbon rims. ABLC smooths airflow across the rim surface, and this latest third-gen iteration features up to four times more dimples than before.AEROBALANCEZipp wheels are race-ready before they are camera-ready. Using a combination of testing methods, Zipp refines aero performance to new levels of excellence. Aerobalance ensures the perfect balance of aero efficiency and crosswind stability.

Zipp 303 Firecrest Carbon Tubeless Rear WheelEngineered to meet the demands of modern road bike adventures, this rear wheel features a hookless carbon rim construction, which allows it to deliver incredibly fast and smooth rolling performance. Zipp has equipped this model with tubeless tyre compatibility, so you can enjoy the benefits of superior stability and control as well as a lighter overall weight. Another highlight of this version is its disc brake compatibility, which means that you'll benefit from powerful and consistent braking performance during the most unpredictable of road conditions.Zipp's 303 Firecrest Tubeless Disc-brake rear wheel is designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It's 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 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, weight. 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 30mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road. The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume, and lower tyre pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tyre and wheel system absorbs the shaking, not the rider. At the centre of the 303 Firecrest Tubeless Disc brake rear wheel is a versatile and durable hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake rear wheel is for dedicated cyclists who aspire to the latest in technology. Its competitors… in races, against peers, or simply conquering personal limits.

45mm Deep The 45mm deep 303 Firecrest delivers unmatched aero performance when used with the wide tires that today’s riding demands. Zipp has achieved this with a wide disc-specific rim design featuring ABLC dimples extending all the way to the outer edge of the rim. In addition to achieving AeroBalance™, the industry-leading crosswind stability and low aerodynamic drag that defines all Firecrest wheels, the new 303 Firecrest delivers lower drag than the outgoing version when used with 25c or wider tyres. The aerodynamic performance gap between a narrower rim and the new 303 grows even larger with 28c and wider tyres thanks to a smoother transition between the tyre’s profile and Zipp's new rim shape. Tubeless Rim Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tyre’s bead in place, ensuring secure performance, even when ridden at lower tyre pressures. Setup tubeless and emblazoned with your choice of three colour decal options (optional extra), 303 Firecrest wheels are as alluring as they are easy to use. And should you choose to run tubed tyres, the new 303 is fully compatible. Durable Carbon Layup A new carbon fibre layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while their robust 77D front hub, paired with 24 Sapim® CX-Ray spokes, keep the wheel stiff and responsive. To ensure compatibility with any bike, Zipp's versatile 77D hub comes with swappable end caps to work with QR’s and thru-axles, including 12x100mm and 15x100mm front thru-axles. And like all Zipp carbon wheels, the new 303 Firecrest is laid up, moulded, drilled and assembled in Indianapolis, USA. Built to take you to places you’ve never been, the 303 Firecrest® Tubeless Carbon Cincher will go the distance. It’ll just take less time. Each Wheel Includes: Zipp Tubeless valve extender and valve-core wrench Zipp rim tape (factory taped) Zipp Tangente quick-release skewer Zipp thru-axle end caps
