  • Giro Helios Spherical Road Helmet (MIPS)

    Created for cyclists who seek the ultimate in performance-focused safety, the Giro Helios Spherical Road Helmet (MIPS) is packed with cutting-edge features to make your ride comfortable and provide effective crash protection.

    Whether you're mixing it up in a local race series, putting in some training miles or out to simply enjoy the thrill of riding fast, should you be unfortunate to crash, the Helios Spherical Road Helmet (MIPS) is designed to offer a high level of head protection. We hope you don't have to test its abilities but thanks to advanced construction and MIPS® Spherical Technology it's got you covered should you fall. 

    MIPS® Spherical Technology

    Protection of the head and brain doesn't get any more advanced than the MIPS® Spherical Technology. This system is designed to reduce the rotational forces of impacts to the head. This is achieved via the dual-layer system whereby the helmets outer is able to rotate around the inner liner during a crash. The progressive layering of both inner and outer layers also offers more comprehensive protection than standard helmets. 

    Comfort is a Breeze

    When you're working hard on the bike, generating big watts and picking up the pace, sweat and heat build-up is inevitable. However, with 15 Wind Tunnel™ vents, the Helios offers a rush of cooling air over the scalp. Air is forced through internal channels to optimise the cooling effect and exhaust vents let damp, warm air out. The rush of speed is matched by the rush of ventilation. You'll also have the sweat-absorbing performance of Ionic+ padding. This anti-microbial padding preventing the sting of sweat running into the eyes and stops an itchy scalp after a sweat ride.  

    Roc Loc® 5 Fit System

    Inside the Helios is the light and airy Roc-Loc® 5 Air fit system. This is the industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing fit and comfort, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.
