It is no secret that aerodynamic drag determines the winners and losers of speed racing by almost 90%. Drag is a force that tries to prevent the quick movement of a bike through the air. This force is created due to the pressure difference between the rear and the front of the bike.
So, with the hump occupying the space between your helmet and your suit, air flows smoothly over your suit to reduce turbulence. Simply put, it reduces the speed of your bike. Apart from enhanced airflow, your tucked position, coupled with an integrated helmet, benefits greatly from the aerodynamics provided by the hump. Once this is in place, you won’t struggle to keep your entire body and head in position while racing.
