The Giro Roc Loc 5 is the newest fit mechanism found on all upper-end Giro helmets as of 2011. This mechanism is not only lighter, but also is an infinitely more secure fitting system than its predecessor. A small dial micro adjusts the closure, while multi-position adjustments within the helmet will allow for variation in dial placement on the back of the head. Keep your helmet in perfect condition for many rides to come with this genuine replacement part.
