Product Story

Product details

Mid-Depth Aero for Road Performance

The Zipp 404 S A1 front wheel is built for riders who want aerodynamic efficiency without sacrificing stability. Its 50mm rim depth draws from Zipp’s WorldTour-proven Firecrest profile, offering a balance between speed and predictable handling in crosswinds. This makes it a versatile choice for everything from fast group rides to criteriums and road races.

Modern Tubeless, Hookless Construction

With a 23mm internal rim width and hookless tubeless design, the 404 S is optimized for 28–40mm tubeless tires. This setup allows for lower tire pressures, improving rolling resistance and comfort across varied pavement. The rim’s straight sidewall construction ensures a secure tire fit and easy tubeless setup.

Hub Platform and Build Details

The wheel features Zipp’s 76D hub with cartridge stainless steel bearings for smooth, reliable performance. A 20-hole, 2-cross spoke configuration with Sapim CX-Sprint spokes provides a blend of stiffness and durability. The wheel is disc brake only, using a Center Lock interface for modern braking performance.

Weight and Practical Considerations

Weighing in at 713g for the front, the 404 S A1 is light enough for climbing yet deep enough for aero gains. Zipp backs the wheel with a lifetime warranty and crash replacement policy, adding peace of mind for committed road cyclists.
