Zipp 404 Firecrest aero profile is the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength, and handling of a wider rim body. The Zipp 404 Carbon Clincher weighs just 1557 grams per set. Zipp 404 Firecrest is designed specially to account for the differences in airflow patterns between clincher tires and tubulars, 404 Carbon Clincher far exceeds the aero performance of any other clincher wheelset in the industry. Zipp engineers knew that a 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, Zipp US-based composites supplier created a new heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that Zipp Firecrest is the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake pad options.
