08/05/10 - ZIPP’S FIRST FULL-CARBON CLINCHER WHEELSET FEATURES NEW AERO PROFILE AND MATERIALS

Zipp Speed Weaponry has revealed details of the company’s highly anticipated 404 Carbon Clincher, the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength, and handling of a wide rim body.

As a result, the 404 Carbon Clincher reaches an unrivaled level of performance for clincher wheels and a total weight of just 1557 grams, putting it among the lightest deep-profile carbon clinchers available.

According to Zipp technical director Josh Poertner, the 404 Carbon Clincher is the only carbon clincher rim currently produced that not only passes the rigorous CEN braking test with no rider weight restrictions but can do it twelve times over, reaching maximum surface temperatures of over 360°C (680°F) with no bead hook deformation – a critical piece of information for riders that live in mountainous regions who are concerned about blown-off tires as they're hurtling down an Alpine descent.
