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.
Firecrest With the industry-changing Firecrest rim shape, Zipp wheels fulfill our missing of making you faster at our most popular rim depths. Not only is Firecrest mor aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality. Firecrest is the first aero profile that effectively controls airflow around the back half of the whell. Its durability is durable enough for the Spring classics as well as years of training and racing.
Showstopper Showstopper technology uses a molded silicone carbide (SiC) surface brake ring for maximum wet braking performance. The result is a braking performance that is equal to that of an aluminium rim, even in torrential rain. Showstopper technology offers greater wet braking power than any other carbon wheel.
