Aerodynamics aren’t paramount in cyclocross, but strong, comfortable wheels are always in style. The 58mm rim profile is a classic in Zipps arsenal that dates back to the early 90s. Now, with the advanced Firecrest aero rim shape, our leading all-around performer is an even greater threat to win any race on any terrain. Thats because Firecrest moves the center of pressure closer to the steering axis, so crosswinds exert lower side force on the wheel. Aerodynamics aside, the 404s new 27mm-wide profile offers a slew of other benefits on the road. The upgraded lateral stiffness makes the 404 even more responsive to accelerations and more precise when cornering. And its composite structure is designed to absorb impacts by flexing slightly outward which gives you a comfortable ride and long-term durability. Even with all these improvements, Firecrest technology hasnt added a gram to the 404 Tubulars weight of just 1278g. On the climbs, it goes toe-to-toe with shallower, less aero rivals. On the flats, it hangs with deeper, less nimble competitors. If any one wheelset can do it all, its the 404.
