The Zipp 404 S was designed from the ground up to offer the fastest possible road wheel at what Zipp calls their “most attractive price point to the discerning cyclist looking to upgrade their experience on the road.”Â
Building upon the groundwork laid by its predecessor, the 303 S, this next-generation road wheel brings industry-leading aerodynamic performance to Zipp’s acclaimed S Collection of wheels. With the 404 S, our S Collection consists of best-in-class products spanning the disciplines of road (404 S), gravel (303 XPLR S), and XC MTB (1ZERO HITOP S.) With a laser focus on paved performance, the 404 S offers advantages over the 303 S in every meaningful way – aerodynamics, hub performance, aesthetics, and price.Â
At 50mm deep, the road-focused 404 S features a mid-depth rim profile that borrows from the WorldTour-proven Firecrest rim design, providing premium level aerodynamic performance while staying shallow enough to maintain stability in crosswinds. This design not only saves about 2 watts over the 303 S, but it also shows similar savings over competitor wheels that come in well over twice the price.Â
