Road performance

The Zipp 404 S is designed for road performance. It offers a clear aerodynamic advantage over a low or mid-profile wheel, while maintaining good versatility.

Stability in crosswinds

The rim height remains sufficiently controlled to ensure good control when weather conditions become variable.

Hookless tubeless technology

Hookless carbon rims

Hookless rims are designed to work with compatible Tubeless Ready tires only. This modern design optimizes tubeless setup, performance, and comfort.

Internal width of 23 mm

The 23 mm internal width allows the use of 28 to 39 mm tires. It corresponds to current modern road standards, focused on comfort, grip and efficiency.

Lower pressures

Tubeless setup allows for lower pressures to be used in order to improve rolling resistance, control and grip on different surfaces.

Construction and hubs

Sapim CX-Sprint spokes
