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 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 Tubular rim-brake is a new versatile and durable hubset, the German-engineered ZR1.
