The dial’s clicks are audible, to allow you to easily tell if the Roc Loc 5 Fit System is being tightened or loosened. The system also features a pair of dual pods.
These are two panels that are crafted to firmly grasp the back of your head while comfortably cradling your occipital lobe, therefore providing extra stability, especially when you are riding on bumpy areas. What’s more, the system comes with a three-position vertical fit tab located just below the micro-adjustable dial. This tab is responsible for adjusting the height of the helmet and the position of the dual pods. For starters, the vertical tab allows up to 15millimeters of up and down adjustment.

What’s more, the P.O.V visor allows up to 15 degrees of vertical adjustment, allowing you to tilt it all the way back if you feel that it’s obscuring your view. However, some giro hex reviews have pointed out that customers do not like the fact that it’s not easily detachable.
