When it comes to getting the most aerodynamics for the dollar, nothing beats an aero helmet. Depending on just how extreme you want to go in terms of shaving off a few seconds, you can find some aero models that still manage to offer enough ventilation to make them reasonable training options, too. Here are a few to pick from.
$349 Designed to offer the best combination of aerodynamics and ventilation, early versions of the Vanquish appeared in Kona last year. The aerodynamic shape slices through the wind with ease, while the large air channels move air through the helmet to keep you cool. The Roc Loc harness allows you to dial in a comfortable fit and the integrated MIPS protection provides added protection in case you crash. Completing the package is an integrated visor that easily clips on and off that utilizes Zeiss optics for crystal clear vision.
$287 Lazer’s premier aero road helmet, the Bullet, incorporates a shortened teardrop shape and a do-it-yourself ventilation system with proven aerodynamics. It has a relatively narrow profile, front to back, that slices through the wind, while the back is designed to create as little noise, or wind turbulence, as possible. The adjustable vent sits front and centre, so while riding fully aero or in cold conditions the vent can be kept shut, then when it warms up you can slide it open. With a secure fit, and a large and accurate retention dial, you can click in a comfortable fit.
