The NAQI Aero Speed Gel uses vortex generators to enhance the turbulence in the boundary layer of the air flow across certain parts of a cyclist.
These enhanced turbulences lead to later flow separation and a corresponding smaller wake and lower drag.
Extensive wind tunnel testing showed a drag reduction of almost 4% when used on only the legs of a cyclist.
When also applied to the shoulder and arms of a triathlete a reduction in drag of almost 6% was obtainable.
