ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel.
Zipp’s sole mission is to help you go faster. That's why our wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator – to refine aero performance to new levels of excellence. Over the decades of innovation, our engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling. This optimizing of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.
Zipp’s TSE Technology (Total System Efficiency) was developed by our engineers in the Nest Advanced Development Lab in Indy. This approach to carbon-wheel manufacturing means the 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced: Wind resistance, rolling resistance, gravity (weight + durability), vibration losses.
