You wanted a lighter helmet, a cooler helmet, a better helmet—so Giro created one. Giro optimized every component in the Aeon Road Bike Helmet including the shape of the helmet itself, reducing weight by 28 percent compared with its predecessor. They also sculpted massive vents with interior channeling for best-in-class cooling power and integrated the adjustability and comfort of Roc Loc 5, for a luxurious feel with all the performance you need.

In-Mold

Giro's in-mold construction process fuses the helmet’s outer shell with its impact-absorbing EPS liner during the molding process, making the liner literally a part of the helmet. This fusion process reinforces areas around vents and ribs, creating a one-piece ‘exoskeleton’ that allows the helmet to be lighter, more durable, and better ventilated than traditional designs.

Roc Loc 5

After more than two years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entirely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still nearly 40-percent lighter than its popular predecessor, Roc Loc 4.

Micro Dial: The heart of Roc Loc 5 is this ratcheting, micro-adjusting dial. A simple, two-finger twist of the Micro Dial opens or closes the retention system and each click is audible.

Three-Position Bracket: It’s never been easier to change vertical positions and fine-tune fit. Giro incorporated a three-position bracket that features 15-millimeters of up/down movement. Like the Micro Dial, this system can be adjusted without removing the helmet. Carefully-crafted ergonomic arms are shaped to be as comfortable as possible, yet work flawlessly with Giro eyewear.

Dual Pods: These two panels are designed to firmly grasp the back of your head while comfortably cradling the occipital lobe.

Strap Baskets: With Roc Loc 5, your helmet straps are always right where you need them. Not to mention this strap basket brings a new level of comfort.

Roll Cage

Roll Cage reinforcement is a tough web of DuPont Nylon molded inside a helmet’s EPS foam liner. It provides an extra measure of strength and integrity that you’ll never notice…unless you need it.

Super Fit

A great helmet is so comfortable that once it’s on, it virtually disappears. Our proprietary three-size Super Fit system is based on “human scale factors” data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury, a helmet that fits 98% of the world’s population, yet looks (and fits) like it was custom made just for you.

Wind Tunnel Ventilation

Giro helmets are developed utilizing Giro's proprietary Wind Tunnel ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

X-Static Padding

In addition to being very comfortable, Giro's X-Static pads provide anti-microbial properties to help keep your helmet fresher, longer. The pads are also machine washable.
