Our first full-carbon clincher wheelset, the 404 Carbon Clincher has been described as the most heavily anticipated wheelset of all time. And following two years of development for its revolutionary rim shape and carbon technology, we’re confident that the 404 Carbon Clincher lives up to the hype.
Its 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. Yet the 404 Carbon Clincher weighs just 1557 grams per set, putting it among the lightest deep-profile carbon clinchers available.
Designed specifically 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 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 US-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.
Naturally, we chose to launch our groundbreaking carbon clincher designs with our most versatile wheelset, the 404. Its 58mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event – triathlons, criteriums, breakaways, field sprints, even Grand Tour mountain stages. Now, the 404 is available with the convenience of clinchers, the light weight of an all-carbon rim, and the unrivaled performance of Zipp technology.
Cosmic Carbone SL features long time proven Mavic aerodynamics: 52mm deep rim, elliptical sidewalls, low count aero spokes. But weight has not been put aside with one of the lightest clincher carbon rim to significantly reduce the inertia. Yet available for any rider, road racers and triathletes!

Road helmet for weight fetishists
Road cyclists are true weight fetishists.
With the new BULLET, CRATONI makes the dream of a sensationally lightweight road helmet at a moderate price come true.
At a weight of just 180 g, the BULLET comes out on top of the international competition. A polycarbonate reinforcement at the rear of the helmet makes up for additional safety.
The outstanding ventilation performance, aerodynamics and not least the design satisfy requirements at the highest professional level.
