{"product_id":"zipp-404-s-carbon-front-road-bicycle-wheel","title":"Zipp 404 S Carbon Front Road Bicycle Wheel","description":"\u003cp\u003eThe Zipp 404 S Carbon Front Road Bicycle Wheel is a 50mm-deep carbon aero wheel built for road riders upgrading from stock alloy wheels who want measurable aerodynamic gains without paying for Zipp's top-tier NSW line. The rim borrows its shape from Zipp's WorldTour-level Firecrest profile, giving it a mid-depth design that's deep enough for aero benefit but shallow enough to stay stable and predictable in crosswinds — a common trade-off for riders who do most of their climbing and racing in variable conditions rather than flat time trials.\u003c\/p\u003e\n\u003cp\u003eThis wheel is the direct successor to the 303 S and slots into Zipp's S Collection alongside the 303 XPLR S (gravel) and 1ZERO HITOP S (XC MTB). Compared to the 303 S, Zipp specifies improvements to aerodynamics, hub performance, and price.
