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.

Searching for flat-out speed? Zipp’s 808 Firecrests are the key. They've proven to be the gold standard for road races, triathlons, and time trials across the globe. The 82mm-deep Firecrest rims are extra wide, which reduces the gap between tire and rim, creating an aero, seamless junction. The wide rims also allow wider tires run at a lower pressure, which diminishes rolling resistance, increases rider comfort, and reduces the chance of pinch flatting. Brilliant in cross winds and light enough to climb like mountain goats, the 808s are ideal for every type of event. They’re built on Zipp’s ultra-stiff hubs with oversize axles to ensure maximal stiffness so every ounce of power gets delivered to the road.
