700c, 27-Inch & 650c

Zipp’s 404s excel in every terrain. They’re exceedingly fast and agile on the flats, in cross winds, up mountains, and out of sharp criterium corners. Zipp’s 58mm-deep Firecrest rims are extra wide to minimize the gap between tire and rim, making them truly aero in every wind condition. This also allows for a wider tire run at a lower pressure, resulting in less rolling resistance, better ride feel, and a reduced chance of pinch flatting. The 404s are feather-light and built up on Zipp’s stiff hubs with oversize axles, ensuring you get every ounce of power to the road.
