rim profile is a classic in Zipp’s arsenal that dates back to the early ‘90s.
These days, the 404 Tubular still winning races from the Queen K to L’Alpe
d’Huez. Now, with the advanced Firecrest aero rim shape, Zipp’s leading
all-around performer is an even greater threat to win any race on any terrain.
controlling airflow around the back half of the wheel, Firecrest makes the
latest version of the Zipp 404 Firecrest Rear Tubular 9 seconds faster than its
predecessor over 40km at a moderate 10-degree wind angle. At higher wind angles,
the improvements are even more dramatic in terms of both speed and stability.
That’s because Firecrest moves the center of pressure closer to the steering
axis, so crosswinds exert lower side force on the wheel.
Aerodynamics aside, the 404’s 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.
all these improvements, Firecrest technology hasn’t added a gram to the 404
Tubular’s weight. 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
wheel can do it all, it’s the 404.
