 "summary": "Giro helmets use a Roc Loc retention system — the adjustable dial at the back that holds the helmet on your head. When it breaks (and it does), most people throw the helmet away. But the retention system is a replaceable part.",

 "answers_question": "Can you replace a broken Giro helmet retention system instead of the helmet?",
 "text": "The Roc Loc 5 retention system on Giro helmets is a plastic cradle with an adjustment dial. After years of use, the plastic tabs that hold it to the helmet shell can snap. First instinct: buy a new helmet.\nBetter instinct: order a replacement Roc Loc 5 unit. They're available directly from Giro or through bike shops. The replacement snaps into the same mounting points — no glue, no tools beyond your fingers.\nWillem's first attempt was to glue the broken tab — it didn't hold. The proper fix was ordering the correct Roc Loc model for his Giro Aeon and snapping it in. Total time: 5 minutes. Total cost: a fraction of a new helmet.\nFrom Willem's repair culture collection.",
