404 S

Designed from the ground up, the Zipp 404 S offers the ideal balance of weight, aerodynamics, and aesthetics to the discerning cyclist looking to upgrade their experience on the road. Building upon the groundwork laid by its predecessor, the 303 S, this next-generation S-level road wheel is fit for road racers, criterium specialists, or any high-performance pavement rider. At 50mm deep, the 404 S rim’s mid-depth profile provides premium level aerodynamic performance while staying shallow enough to maintain stability in crosswinds. Paired with a 23mm internal rim width, this TSS wheel allows for 28-40 mm width tires to be run at lower pressures for optimal rolling resistance and control on nearly any road condition.
