Why We Like The Garneau P-09 Helmet

The Louis Garneau P-09 time trial helmet takes aerodynamics very, very seriously. The front part of the helmet is designed to have as little surface area as possible, and the dimpled surface disturbs the air just enough to increase the flow over the helmet. The tail, which is supported internally, moves air efficiently over the shoulders. Garneau also built a port into the P-09 that allows air to enter at the front, into a channel that exits just behind the ears to release any forward pressure. The vent also works with evacuation channels to improve airflow and provide cooling ventilation.

The lens system flips up and out of the way to ease entry and exit. It can be removed with just one hand. Garneau’s Spiderlock Pro II keeps the helmet in place and includes a polymer neck support the can be adjusted on the fly with the retention dial. Finally, the length and position of the straps can be adjusted with the Steplock divider, which utilizes a locking cam design.
