The Giro Advantage 2 is the best-selling aero helmet of all time. And for good reason; it works. Now you can get one at a fraction of it's original price which is amazing, because the original list price was always considered a great value. We all now know that wind tunnel testing confirms the aerodynamic benefit of a TT helmet, which is almost always greater than benefit of aero wheels. This makes an aero helmet a must for riders seeking the best possible time. Unlike many other aero helmets, the Advantage 2 weighs in at a scant 310 grams, which is only approx one ounce heavier than most standard road helmets of this caliber. The Advantage 2 has the same well-tested aero shape as the Giro TT helmets that has become familiar in the professional peleton.

The Advantage 2 features the winning Roc Loc® 5 retention system for easier fit, better security, 40% lighter weight and improved strength. Roc Loc 5 features 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.
