HJC Adwatt Time Trial Helmet - White

HJC Adwatt Time Trial Helmet As the fastest aero helmet ever tested in the Bike Valley wind tunnel, the ADWATT is in a class of its own. In close cooperation with the reigning TT European Champion Victor Campenaerts and the HJC engineers, the helmet was tested and developed in the Belgian wind tunnel until all involved persons were more than satisfied with the result. Thanks to the curvy shape, the helmet delivers fantastic and almost identical aerodynamic values with and without shield. At the same time, the Venturi Dynamics System provides maximum ventilation.
