Giro Helmet Roc Loc 5 Fit System
The Giro Roc Loc 5 is Giro's patented helmet fit and stabilizing system. Genuine Giro replacement part. The Roc Loc 5 replacement hugs the back of your head and reduces the tendency of your helmet to shift forwards or backwards. Unlike most systems, the Giro Roc Loc 5 design provides adjustable tension that is independent of the helmet straps. What this means is that you don't have to over-tighten the straps to get a snug, comfortable fit.
The Giro Roc Loc 5 fit system is the world's finest. It features separate tensioning and positioning adjustments plus a soft rubber over-molded fit belt that hugs your head in luxury.

NOTE: Roc Loc systems are designed to fit ONLY the original helmet. You can not retro fit a helmet with a later model Roc Loc.
