Giro Helmet Synthe Roc Loc Air
The Roc Loc Air Synthe is Giro's patented helmet fit and stabilizing system. The genuine Giro Roc Loc Air replacement part hugs the back of your head and reduces the tendency of your helmet to shift forwards or backwards. Unlike most systems, the Roc Loc Air 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 Air fit system is the world's finest.
- Genuine Giro Replacement Part.
NOTE: This Roc Loc Air will ONLY fit the Giro Synthe helmet. The Roc Loc Air on the Synthe MIPS model CAN NOT be replaced.
Here is a short instructional video showing how to install a Roc Loc Air in your Giro non-MIPS Synthe bicycle helmet.
