I want to have the strap on my helmet replaced. I saw a helmet I liked fastened to the little helmet bracket on the back of someones bike so chopped it off with a stanley knife and now I can't fasten it up........ Not really, it just sounded a bit more interesting than the boring crap you're about to read. I really like my helmet bar one thing, it has a seatbelt style strap clip, and if you tighten it up at the start of a ride it's loose about 2 hours later, my old helmet had a ratchet fastner which was great, and the one before that had had a double d fastening. Either one of those would do me. Does anyone know anywhere that would be able to sort this? It's an AGV S4 by the way. Cheers all, Toby
