Excited about our new Havoc Pro Lightning Scooter clamp. Made from Aircraft grade aluminum makes for an extremely durable, and lightweight clamp. Included in this clamp system is a Shim used to run our standard sized bars (31.8mm) or if you are running oversized bars (34.9mm) all you need to do is remove the shim and you are ready to go. You will have no troubles finding a color you like with 9 to choose from!
