The Zipp 404 S wheelset is built to be the fastest road wheelset Zipp make at this price — flagship-derived aerodynamics without the flagship cost. Stepping on from the 303 S, it takes its 50mm mid-depth rim profile from Zipp's WorldTour-proven Firecrest design, delivering premium aero performance while staying shallow enough to keep the bike composed in crosswinds.
Zipp claim the 404 S saves around two watts over the 303 S, with similar gains over rival wheels costing well over twice as much. Both rims are hookless, tubeless-only Tubeless Straight Side designs, so with modern tubeless tyres they run lower pressures for a smoother, faster, grippier ride. At a claimed 1545g the pair (707g front, 838g rear) it's light enough for all-day road riding as well as fast-day efforts.
The wheels spin on Zipp's 76 and 176 hubs with 36 points of engagement for quick, reliable pick-up, laced with durable Sapim CX-Sprint spokes in a 2-cross build. Supplied as a front and rear pair with a choice of SRAM/Shimano HG or SRAM XDR freehub, in Dark Grey or White.
