Without wind tunnel testing, we can’t say whether or not the Tempor is faster than a traditional aero helmet. Furthermore, aerodynamic performance depends on the individual. Functionally, however, it is notably different than traditionally shaped aero lids. For one, it reduces the sensation of air whizzing by the ears and neck. Looking downward changed the passing airflow so significantly it could be felt reconnecting with the back at a different point. Despite two substantial vents above the forehead, the Tempor created the perception of less air rushing by then head than a more typical aero option.
