Zipp’s 303 Firecrest Tubeless rim-brake wheelset is an all-around wheelset 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. At Zipp, we never rest on laurels. This wheelset features a 19mm internal width and is tubeless ready. That means you can run lower tire 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 our top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance™. Zipp’s ShowStopper™ textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. At the center of the 303 Firecrest Tubeless rim-brake is a new versatile and durable hubset, the German-engineered ZR1.
