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. Rim Brake Compatible Zipp’s ShowStoppertextured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the center of the 303 Firecrest Tubeless rim brake is a new versatile and durable hub, the German-engineered ZR1. Item Top Features Continued: - Zipp graphics and cosmetic identity that scream speed - New ZR1 hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Tubeless ensuring secure performance even when ridden at lower tire pressures - Versatile 45mm rim profile that’s fast, stable and versatile - ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel - Showstopper textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions - XDR or SRAM/Shimano driver bodies available to select - Ships with QR end caps, quick-release skewers - Campagnolo driver body sold separately Technologies: Showstopper: Our industry-leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. 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.

At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp® 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With an all-new disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. 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 our robust 77/177D hubset, keep the wheels stiff and responsive.Things To RememberAero, durable, Light weight, Tubeless,77/177 hubset,Thru-axle compatible,.
