Giro Roc Loc
The Roc Loc is Giro's patented helmet fit and stabilizing system. The genuine Giro replacement part Roc Loc hugs the back of your head and reduces the tendency of your helmet to shift forwards or backwards. Unlike most systems, the Roc Loc 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 system allows you to adjust the fit while the helmet is on your head. Micro-adjust the tension for a custom fit. The Roc Loc is ponytail compatible.

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