Giving more than simply speed and protection, the Procen ensures you stay cool and comfortable through the intense efforts of a time trial. Proven to be fast thanks to extensive CFD testing and time on the track, the helmet utlises the Venturi effect to manage airflow through and around the helmet for ultimate speed. A distinct trailing edge pushes air away from the shoulders to further aid aerodynamics and management of airflow to find ultimate speed. Large ventilation inlets at the front of the helmet help force air through and around the helmet, providing whole-head cooling and using the Venturi effect to optimise airflow around the head and shoulders. The Procen utilises an innovative 2-position lens system to overcome a problem common with all visor helmets: lens fogging. In the 'start position', the lens sits around 10mm away from the helmet to ensure air can move naturally, ideal to prevent fogging while in the time trial start gate. It's also possible to ride with the lens in this position, with a clear line of site in all directions. The visor lens is fully detachable, and will also break away from the helmet in a crash thanks to an innovative temple design. A comfortable whole-head adjustment system makes it easy for every rider to find a secure fit, ensuring optimum protection while delivering maximum speed.
