After increasing training volume and quality and improving your position on the bike, an aero helmet is the next best bang for your buck. Their teardrop shapes and reduced vents lessen drag as wind pounds into your head and over your back. Even when you tilt your head down and point the long tail of an aero helmet straight up, you are still producing less drag than a road helmet. There isn't much of a downside apart from looking a bit strange. Just put one on and save around 30 seconds per 40k. Simple! But which helmet is best? Well that depends, as usual. Austin Tri-Cyclist takes a look at four models we carry and breaks them down for you. Even better – to celebrate the 2011 Longhorn 70.3 race all in-stock aero helmets are on sale 20% off list price for race weekend!
What's in a Helmet?
The most important consideration in choosing an aero helmet is how well it fits your body and position. You want a helmet whose tail fits closely against your back, and one that is no larger than it needs to be. Pick the smallest size that fits you comfortably, and spend a moment to determine how well it fits against your back. Customers are welcome to set their own bikes up in our fitting center and see how different helmets look on video.
Visors can improve aerodynamics, but many riders prefer to use their own sunglasses. All of the helmets in this review allow you to remove the visor if you don't want it. Ventilation can also be a big concern for some in the Texas heat. Vents will reduce the aerodynamic advantage of a helmet, but if you don't want them, you can always put some packing tape over the vents for cooler days or for shorter events. None of these helmets differ in their weight enough to be a performance concern, but less weight could be a comfort advantage for some riders.

Louis Garneau Superleggera
Garmin Cervelo, Tour de France TTT champs, who take their time trialing very seriously. A visor is included with this helmet.
Giro Advantage 2
Dave Zabriske. This helmet was a breeze to put on and adjust and should work well for triathletes. There is no mechanism for a visor to be installed so sunglasses are not optional. If you prefer wearing your own eyewear anyway, save some money and give this helmet a try.
