Without Limits
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. At Zipp, they never rest on laurels. This wheelset 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 the pinch flats. 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 Zipp's top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which Zipp call 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 a new versatile and durable hubset, the German-engineered ZR1.
