POC has released a new time trial helmet named the Procen. The Procen aero-optimised time trial helmet has been developed in collaboration with the EF Pro Cycling teams, and debuted with EF Education-TIBCO-SVB on the 1st of May at La Vuelta Femenina. It will also be used by the EF Education-EasyPost men's team at the upcoming Giro d’Italia.
POC says the Procen has been designed to drain the high-pressure zone found at the front of the helmet. This creates stagnant air and additional air resistance that riders then need to push through; instead, the Procen guides air through the helmet itself. POC claims the Procen creates the Venturi effect inside the helmet which creates superior ventilation and cooling. The Venturi effect, named after Giovanni Battista Venturi, is a little techy to succinctly explain here but focuses on lowering static pressure, useful in time trial helmets.
