This retention system for Giro helmets replaces your existing worn-out RockLock system
Black with Silver Decals
Easy to fit
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. Purchase this as a replacement of a worn out Roc Loc 5 to keep your helmet going.
