Giro Ionos Helmet - Bicycles

Giro Ionos Helmet 2011 features: 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 (what we call Super Fit engineering).

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

The use of composites in the sub-frame provides incredible structural support, impact dispersion and resistance to penetration.
