Zipp’s 303 Firecrest Tubular rim-brake wheelset offers key innovations for performance-minded cyclists. This is the game-changing wheelset designed to conquer Roubaix and Flanders. Retaining their versatile 45mm rim depth, 303 Firecrest Tubular rims feature construction designs for impact protection. When it comes to pure speed, the 303 Firecrest Tubular packs a serious punch. It’s lightweight with 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 call AeroBalance™. Zipp’s ShowStopper™ textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. At the centre of the 303 Firecrest Tubular rim-brake is a new versatile and durable hubset, the German-engineered ZR1.

SHOWSTOPPER
Zipp's 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 Zipp wheels are race-ready before they're camera-ready. For years, Zipp has used a combinaton of testing methods, including 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, Zipp engineers have learnt 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 work together with thw new HexFin ABLC dimples for improved airflow.
