Helmet: Giro Air Attack
Progression: Blending aero and road
It resembles a BMX helmet, but the Air Attack’s clever design strikes the mid-point between road helmets and full-on aero options. Giro says its aerodynamic performance splits between their fully vented Aeon road helmet and the nearly vent-less long-tail Selector. It’s a great way to buy some free speed on a group ride without looking like you’re trying too hard, or for hot races. If you’re only going to own one helmet for training and racing, this might be the one.
