Zipp 404 S 2027: Accessible Aerodynamics Redefines the Standard
With the launch of the 2027 collection, Zipp brings WorldTour aerodynamic design to its S-Series, dedicated to enthusiasts who demand top-tier performance without the prohibitive price of "Halo" models. The new Zipp 404 S is not just a simple update, but a wheelset redesigned from the ground up to become the new benchmark in the 50mm wheel segment.
The Project: Firecrest DNA at an Affordable Price
The 404 S borrows the architecture of the Firecrest rims used by professionals, offering a 50mm profile that perfectly balances aerodynamic efficiency and stability in crosswinds. According to Zipp, these wheels are not only faster than the previous 303 S (saving 2 watts), but in comparative tests, they outperform competitors that cost more than double.

Why the 404 S Are the Smart Choice for 2027
The strength of the Zipp 404 S lies in their ability to democratize performance. While the market pushes toward increasingly expensive wheels, Zipp uses the engineering of its top-tier models to create an "all-rounder" product: aerodynamic for the flats, stable for crosswinds, but light enough not to struggle on hilly routes. With a 23mm internal channel, they are perfectly aligned with modern trends that see the use of wider tires, ensuring rolling resistance is reduced to the absolute minimum.
