Zipp’s 404 Firecrest Tubeless Disc-brake wheelset is a go-to speed weapon for any situation. Its aero and crosswind-stable 58mm rim depth is ideal for road races, time trial and triathlon, gran fondos, and endless training over all types of terrain. This wheelset features new Zipp cosmetics for that perfect pairing of speed and style. The 404 Firecrest Tubeless Disc brake is infused with technologies developed in our Indianapolis advanced development lab.

Firecrest With the industry-changing Firecrest rim shape, Zipp wheels fulfill our missing of making you faster at our most popular rim depths. Not only is Firecrest mor aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality. Firecrest is the first aero profile that effectively controls airflow around the back half of the whell. Its durability is durable enough for the Spring classics as well as years of training and racing.
ABLC Sawtooth zipp´s 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 ahigher 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.
