The Giro Advantage 2 is the ultimate helmet to wear when every second counts. Wind tunnel testing confirms the aerodynamic benefit of an Aero helmet is often greater than aero wheels making an aero helmet a must for top contenders or any riders seeking the fastest time possible.

Unlike many other aero helmets it only weighs 310 grams which is only about an ounce heavier than the featherweight Atmos. The Advantage 2 has the same well-tested aero shape as the Giro TT helmets that the pros use.

The Advantage 2 now features the Roc Loc® 5 retention system for easier fit, better security, 40% lighter weight and improved strength. The Roc Loc 5 has a small, ratcheting, micro-adjustable dial that can be turned with two fingers for a super-easy on the fly adjustment. The Roc Loc 5 also has a low-profile, three-position vertical fit tab that allows for up to 15mm of up-and-down adjustment.
