At Zipp, they never rest on their laurels. This carbon fibre road bike wheelset features a 19mm internal width and is tubeless-ready. That means you can run lower tyre pressures for greater cornering grip and compliance, plus reduced rolling resistance without the risk of pinch flats.
When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. It’s very lightweight as it has ABLC™ Sawtooth™ Technology, a complex dimpling pattern first developed for Zipp’s top-level NSW wheel lineup. This technology helps to achieve the optimisation of low aerodynamic drag and crosswind stability, which Zipp calls AeroBalance™.
Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the centre of the 303 Firecrest Tubeless rim-brake is an updated and versatile and durable hubset, the German-engineered ZR1.
Updated Zipp graphics and cosmetic identity that scream speed
Updated 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 airflow around the rim and contributes to creating a faster, more stable wheel
Showstopper™ textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions
Ships with QR end caps, quick release skewers
Campagnolo driver body sold separately
Zipp wheels, handlebars, stems, and seatposts come with a lifetime warranty for product issues while riding. The lifetime warranty is not transferrable. Proof of purchase is required.
Zipp's industry-leading silicon carbide Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.
Zipp’s Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.
Zipp’s sole mission is to help you go faster. That's why its 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, its engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimising 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 works together with Zipps updated HexFin ABLC dimples for improved airflow.
