It's a vital component of the Total Efficiency System, or TSE, an approach to speed in ever-changing road and driving conditions. Specifically, TSE focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance and vibration losses.Zipp's ABLC Sawtooth technology uses an intricate dimple pattern to improve aerodynamic efficiency. The use of hookless (straight side) tires on the 404 Firecrest is an integral part of Making You Faster. With the hookless system, the transition between the rim and tyre is smoother and more aerodynamic.
