IMPROVED VENTILLATION
Better vent position Our CFD studies have allowed us to optimize the position and dimensions of the front opening.

Deeper evacuation channel More and deeper evacuation channels allow for a better airflow.

Front Plug A plug is also available to close the front opening.
IMPROVED AERODYNAMICS
Frontal surface reduced to a minimum To reduce the helmet's frontal surface, we started with the inside. A study of morphology allowed us to improve our helmet's inner shape. With the help of CAD tools, we then optimized the foam wall's thickness. The helmet became more compact while remaining very comfortable. When aerodynamics are concerned, every unnecessary millimeter has a negative influence that becomes a burned watt. It is therefore vital to wear a helmet that is exactly the right size. Our helmet is available in three sizes and each one has been optimized to offer riders of all sizes the very best performance.

Boat Tail When we try to improve the helmet's aerodynamic performance, it is very important to consider the whole moving body. When the cyclist is riding, a large quantity of air moves from the chest to the back. To allow a better airflow at the shoulders, the inferior part of the tail is reversed, which limits turbulence at the lower part of the helmet.

Speed Port Even when the helmet is worn with a visor, air always enters the helmet though the face. This air becomes trapped at the ear area, which increases pressure and slows the rider. By adding vents behind the ear, we created an airflow towards the rider's back, thus releasing the pressure.
IMPROVED LENS SYSTEM
Visor lifts up to facilitate entry for a fast and easy transition. Can be easily removed with only one hand.

RETRACTABLE EAR
(INTERNATIONAL PATENT PENDING)
The retractable ear flaps open and close smoothly and effortlessly for a fast and easy transition without compromising the helmet’s aerodynamics.

REMOVABLE FRONT PLUG INCLUDED

FLIP-UP LENS

SPIDERLOCK® HELMET STABILIZING SYSTEM
(USA: 7,114,197)
This precise rack-and-pinion mechanism is independent from the strap system and can be easily tightened on the head using only one hand for a perfect fit around the head and to keep the helmet in place.

SPIDERLOCK® PRO TT

Helmet stabilizing system independent from the strap system. It has a light and ventilated polymer neck support for added comfort. 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.

Alphamantis’ innovative Track Aero System (TAS) is cutting edge technology that allows real-time testing of aerodynamic efficiency while riding. This industry-changing technology brings wind tunnel to the real world. The system allows us to measure a rider’s CdA (coefficient of drag) while he/she rides and enables us to conclusively measure the effects of even the smallest details on the equipment design, ultimately improving the performance of our apparel and equipment.

The next generation of TT helmets is here. A true revolution in aerodynamic helmets, designed to be faster than the competition. The P-09 helmet utilizes the innovative technology of the Vorttice helmet with improved aerodynamics, improved ventilation, and an improved lens system. The frontal surface is reduced to a minimum, making the helmet more compact. The inferior part of the tail is reversed for a better airflow at the shoulders, and a Speed Port allows air that enters at the front of the helmet to exit through vents behind the ears and release any pressure. A better vent position combined with additional and deeper evacuation channels allow a better airflow for an improved ventilation. The improved lens system includes a visor that lifts up for a fast and easy transition, and that can be easily removed using just one hand.
