Some of the proprietary technology’s used in the new Zipp 404 NSW IMPRESS™
Zipp’s ImPress graphics technology prints graphics directly on the rim, to help allow the dimples to do what they were designed to do – control vortex shedding, the rate at which air sheds off the wheel. We also love the way the look.
ABLC SAWTOOTH™ TECHNOLOGY
Sawtooth dimple design consists of 12 nodes that are precisely 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.
SHOWSTOPPER™
Our industry leading silicon carbide Showstopper™ brake track delivers unmatched stopping power and modulation regardless of weather conditions or the length of the descent. With Showstopper™ braking performance, you’ll need to find another excuse not to ride on rainy days.
