Zipp’s first full-carbon clincher wheel, the 404 Carbon Clincher has been described as probably the most heavily anticipated wheelset of all time. And following two years of development for its revolutionary rim shape and carbon technology, Zipp is confident that the 404 carbon clincher lives as much as the hype.
Its Firecrest aero profile is the primary deep-profile carbon clincher design to supply some of the best aerodynamics, ride quality, strength, and handling of a much broader rim body. Yet the 404 Carbon Clincher weighs just 1557 grams per set, putting it some of the lightest deep-profile carbon clinchers to be had.
Designed in particular to account for the diversities in airflow patterns between clincher tires and tubulars, 404 Carbon Clincher a long way exceeds the aero performance of every other clincher wheelset in its class.
As Zipp proved with the Paris-Roubaix-winning 303 Tubular, a much broader rim offers greater vertical compliance for keep watch over and luxury on rough surfaces at the same time as increasing lateral stiffness for sprinting and cornering. The similar holds true for Firecrest rims with clincher tires. And as 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 result in spikes in rim temperature and tire pressure that have an effect on performance and handling – especially with clincher tires. To unravel this challenge, our US-primarily based composites supplier created a brand new heat-resistant resin exclusively for Zipp. This technology improves the warmth dissipation so substantially that ours are the one carbon clinchers to pass stringent European safety checking out without limitations on rider weight or brake pad options.
Naturally, Zipp chose to launch their groudbreaking carbon clincher designs with their such a lot versatile wheelset, the 404. Its 58mm rim depth is a classic all-around performer that
