The Louis Garneau Superleggera helmet debuts at the Tour of California upon the noggins of the Team Type 1 and Rock Racing riders, and is the company’s latest time trial specific design.

The helmet, as with most time trial components these days, was tested extensively in a wind tunnel so it should mean Louis Garneau will be able to back up its claims that the helmet “pushes the limits of performance through the study of laminar airflow, weight reduction, and redistribution of weight to allow for a longer aero position."

The aerodynamically designed helmet features two front vents and three rear exit ports, is 50g lighter than its predecessor and has been designed to sit on the head in a way that "creates less fatigue at the neck area and makes it easier for the rider to maintain an aero position."

Most notably of the changes to this new helmet is the ‘dimpled’ front section, as used on golf balls and Zipp rims, which "...causes the flow to transition from laminar to turbulent," says Louis Garneau.

An optional ventilated visor increases aero properties when used in conjunction with the helmet.
