Zipp s 303 Firecrest Tubeless Disc-brake 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.

When it comes to going fast on a bicycle, efficiency means reduced: Wind resistance, rolling resistance, rider fatigue, 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 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 is a versatile and durable new hub, the German-engineered ZR1 DB. This hub features 66 points of engagement for quicker response.

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
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.

This rim features legendary Firecrest technology, providing outstanding aerodynamic performance, straight-line power transfer efficiency, great stability in crosswinds and is perfect for climbing due to its weight. They deliver precise handling and stability on adrenaline fuelled descents and snappy acceleration when putting the power down. Firecrest Design Benefits The fundamental benefits of the Firecrest design are that its shape moves the centre of air pressure backwards, giving the 82mm deep rim the crosswind stability of a much shallower rim. Also, the 26mm wide brake track (at centre) enables the Tubular tyre to achieve a wider, more stable profile without compromising rolling resistance. Exceptional Rolling Efficiency At the centre of this wheel is the Zipp 177 hub, which features unmatched durability and advanced bearing protection, with no bearing pre-load required. This hub provides exceptional rolling efficiency and a consistent performance output that you will be hardpressed to find a rival in the same wheel class.
Zipp’s 303 Firecrest Tubeless rim-brake rear wheel is an all-arounder for a new era of road riding. It’s rich in heritage yet loaded with innovations. It’s as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints. Tubeless Ready Road Bike Rear Wheel At Zipp, they never rest on laurels. This rear wheel features a 19mm internal width and is tubeless ready. That means you can run lower tyre pressure for greater cornering grip and compliance with reduced rolling resistance without the risk of pinch flats. Lightweight Carbon with ABLC Sawtooth Technology When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. It’s lightweight with ABLC Sawtooth Technology, a complex dimpling pattern first developed for the brand's top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which they call AeroBalance.

ABLC Sawtooth: ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel. AeroBalance: Zipp’s sole mission is to help you go faster. That's why our wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator – to refine aero performance to new levels of excellence. Over the decades of innovation, our engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling. This optimising of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.
