SUPERLEGGERA HELMET :: Louis Garneau - $180

A new texturized front area simulating a golf ball effect creates a better laminar flow. The overall weight reduction and a forward move of the center of gravity will create less fatigue at the neck area in an aero position allowing the rider to maintain the aero position for a longer period of time and prevents the low head drag. The helmet is also equipped with 2 huge front vent inlets and 3 large back vent outlets for maximum airflow without compromising aerodynamics. The Superleggera is the featherweight of helmets, and is so light you forget you are wearing it. With the notable, Spiderlock Elite Retention System which uses a rack and pinion mechanism for quick and accurate adjustment using only one hand.

Does this require the head of the bicycler to be detached and spinning?
