Most turbulence created by the bike is caused by the wheels ( and spokes). At the top of the wheels, the spokes are moving forward while colliding with the frontal wind. This causes a major turbulence, creating drag and slowing down the bike. With our Splitfork we gide the incoming frontal air away from the spokes and create in this maner an airsteam, away from the wheels. In this way, we reduce the interaction of the airstream with the spokes, whch results in reduced turbulence & drag.
