The latest iteration of the 303 Firecrest Carbon Clincher is infused with technologies refined in Zipp's Indianapolis advanced development lab. The results mean better performance out on the road: More speed, better control, and greater stopping power than its predecessor: 

More Speed: Revised rim profile for reduced aerodynamic drag developed by Zipp's advanced development team in Indianapolis, Indiana, USA. 

Greater AeroBalance™: ABLC™ Sawtooth™ Technology, a complex dimpling pattern first developed for the top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which Zipp calls AeroBalance. 

Better braking: Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. 

Lighter Weight: The 303 Firecrest Carbon Clincher is 65 grams lighter than its previous iteration. 

In both tubular and clincher versions, the wider Firecrest design better protects tires and places more rubber on the road while cornering without adding rolling resistance. A wider rim offers greater vertical compliance for control and comfort on rough surfaces while increasing lateral stiffness for sprinting and cornering.
