Zipp 303 Firecrest Carbon Tubeless Rim Brake 700c Rear

WITHOUT LIMITS

The 303 Firecrest Tubeless rim-brake wheelset is an all-around performer designed for a new era of road riding. Rich in heritage yet loaded with modern innovations, this wheelset is as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints. Featuring a 19mm internal width and tubeless-ready construction, it allows for lower tire pressures, providing greater cornering grip and increased compliance with reduced rolling resistance and a lower risk of pinch flats.

When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. It utilizes ABLC™ Sawtooth™ Technology—a complex dimpling pattern that optimizes low aerodynamic drag and crosswind stability, a balance known as AeroBalance™. For reliable stopping power, the ShowStopper™ textured braking surface delivers unrivaled rim braking performance in both wet and dry conditions. At the heart of the wheel is the German-engineered ZR1 hubset, offering a versatile and durable foundation for any journey.
