Zipp 404 Firecrest Carbon Clincher

  • Description

Designed specifically to account for the differences in airflow patterns between clincher tires and tubulars, the 404 Firecrest Carbon Clincher far exceeds the aero performance of any other clincher wheelset in its class. As Zipp proved with the Paris-Roubaix-winning 303 Tubular, a wider rim offers greater vertical compliance for control and comfort on rough surfaces while increasing lateral stiffness for sprinting and cornering. The same holds true for Firecrest rims with clincher tires. And because the hook beads are farther apart, the tire itself takes on a more stable shape without adding rolling resistance.

Heavy continuous braking on carbon surfaces can cause spikes in rim temperature and tire pressure that impact performance and handling – especially with clincher tires. To solve this challenge, our U.S.-based composites supplier created a new heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that ours are the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake pad options.
