The 404 wheel design provides lightweight, super-stiff and reliable performance while its superb aerodynamic design ensures exceptional stability and efficiency in any situation; this wheel is ready for any challenge.
Boasting deep section performance benefits, the 404 Firecrest rim profile carves through the air and provides significantly advanced power-transfer and stability even in the strongest of crosswinds. This wheel design pushes much further beyond the performance benefits that are offered by every other clincher wheel design in its class, enabling it to deliver the highest levels of performance and power transfer.
Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking.
The Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.
A unique to Zipp rim profile that provides more aerodynamic finesse than any other rim design. It also improves handling in crosswinds significantly and increases the ride quality enormously.
Using a vibration absorbing material that is compressed between layers of solid carbon laminate on the rim surface. This technology means that when the rim received an impact from the road, a lot of the shock is absorbed by the VCLC system, resulting in a 10% reduction in road vibration.
