The next generation, now.

The next generation of TT helmets is here. A true revolution in aerodynamic helmets, Louis Garneau's P-09 Helmet designed to be faster than the competition and developed with Alphamantis. The P-09 helmet utilizes the innovative technology of their Vorttice helmet while adding in improved aerodynamics, improved ventilation, and an improved lens system. The frontal surface is reduced to a minimum, making the helmet more compact while starting the golf ball-like textured surface for improved laminal airflow. The inferior part of the tail is reversed for a better airflow at the shoulders, and a Speed Port allows air that enters at the front of the helmet to exit through vents behind the ears and release any pressure. A better vent position combined with additional and deeper evacuation channels allow a better airflow for improved ventilation. The improved lens system includes a visor that lifts up for a fast and easy transition, and that can be easily removed using just one hand.

The Louis Garneau P-09 Helmet includes the P-09 Smoke 7F7 lens. Claimed weight: 350 grams.

This product has given me renewed motivation to get out and ride

I like that this helmet weighs less than my old non aero helmet. I get less wind noise even though going faster. One of my concerns was that it would be too hot in warmer weather. This has not been the case. For my usual time on the bike 1 to 2 hours the recent 80 degree temperatures have not been a problem. Maybe because I am moving so much faster now, lol.

I settle into the aero position and just keep accelerating. Before I know it there are no more gears on my Compact gear set. Time to replace the chain and get bigger chain rings.

My only issue so far is that my big head is pushing my ears against the flexible ear flaps, which can become irritating. I deal with this by wedging the ear flaps open about a 116 with a piece of rubber foam.
