To optimize aerodynamics, air must circulate inside as well as outside the helmet. The « aero » cage was thus designed in order to let the air flow in without restriction. The evacuation channels then guide the air to the back of the helmet.
Internal frame system reinforces the helmet’s structure and enables huge vents to be created without jeopardizing protection.
Helmet stabilizing system featuring a polymer neck support. It can be easily tightened on the head using only one hand, thanks to its dented anti-slip wheel. Its inclination can be adjusted to several positions.
Wind-tunnel (CFD) software enabled us to test the aerodynamic performances of several helmets on the market. Our analysis determined that it was possible to create a helmet offering a highly superior performance by optimizing its frontal surface (the surface of the helmet which faces the wind). We therefore designed the helmet directly on the head of a rider in a cycling position. The result is a helmet which follows the shape of the head without excess of material at the back, allowing a better air evacuation, from the front of the helmet to the cyclist’s back. In order to reduce the high pressure zone in front of the helmet (in red on the image) each opening was designed in order to optimize the passage of the air inside the helmet. This air which provides a resistance to the cyclist is then pushed inside the helmet, circulates in the evacuation channels and is then ejected to the back of the helmet at the same time as the heat released by the cyclist’s head. The development of this technique stems from several tests performed during the design of the Vorttice helmet.
