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 guide the incoming frontal air away from the spokes creating an airstream away from the wheels. In this way, we reduce the interaction of the airstream with the spokes which results in reduced turbulence and drag.
