The Ventral SPIN racing bike helmet sets new standards in aerodynamics, ventilation and safety. Its unique design makes it the fastest helmet POC has ever developed, thanks in part to the help of the Cannondale Drapac ProCycling Team, the aerodynamics specialists at the in-house WATTS Lab, and countless CFD simulations and tests.
The special design of the Ventral directs air through the helmet rather than around it. This reduces the suction behind the helmet and increases the aerodynamics. In addition, the Ventral SPIN has its own zones embedded in the EPS for optimized airflow. The pressure difference of maximum dynamic and minimum static pressure generated by the so-called Venturi effect increases the air velocity and thus ensures better aerodynamics. The zones for the air flow also have the effect of cooling the head, which again benefits the wearer and his performance.
The airflow that passes through and around the helmet is favored by the special shape of the ventral: The spoiler at the back of the head reduces turbulence while providing a longer linear airflow to the rear.
In order to fulfil its mission, POC always develops its helmets with regard to the entire helmet, i.e. the interaction of all materials and features. Despite its light weight, the Ventral SPIN has a safe unibody construction and an EPS core that represents a perfect balance between weight and safety. SPIN (Shearing Pad INside) is POC's patent-pending silicone pad technology, which uses innovative materials to enhance protection in combination with the core and shell. Thanks to its simple size adjustment system in circumference and height, the Ventral is comfortable to wear. The redesigned Eye Garage ensures a secure grip of the glasses on the helmet.
Oblique impact protection is necessary to counter the forces involved in non-linear impacts, which are a common cause of head injury. SPIN (Shearing Pad INside) pads are integrated inside a helmet and add an extra layer of oblique impact protection by shearing in any direction, reducing the force transmitted to the brain. The most common type of fall results in an angled, or oblique, impact with the ground or object which can lead to a rotation of the helmet and head.
Research has shown that compared to a direct, or linear, fall the force required to cause serious head injury from an oblique impact is often much lower. To counter this common impact scenario, POC created SPIN pads which are an evolution on nature’s own design and use an innovative pad technology and design. SPIN pads are optimized to provide oblique impact protection based on the precise location inside the helmet and by using various pad technologies which can shear in any direction. The aim is to minimize the effects of an oblique fall by allowing the helmet to move relative to the head.
