At first glance, the design of the VENTU model is inspired by top racing helmets. The top combination of aerodynamics, revolutionary ventilation and perfect comfort will be appreciated especially by those who are really serious about cycling. The aerodynamically efficient helmet's shape improves the characteristics that have a major effect on the airflow around the helmet. The precisely designed low profile of the helmet uses the Venturi effect, thanks to which the air supply through the massive air vents in the helmet is maximized and the aerodynamic drag is minimized. The drawn in air is led through the helmet and contributes to excellent ventilation of the inner part of the helmet. However, comfort is important as well, therefore VENTU has a fully adjustable ergonomic sizing system, which adapts optimally to the shape and size of the head and ensures a comfortable and safe fit of the helmet on the head. The ultra light weight of the helmet is a key parameter that will withstand the competition at the highest level. With this helmet, you will whizz a little faster than you have been used to.
