Hand designed by Lucky's team riders and then computer engineered by Lucky's design team, The Lucky Double Clamp is a stylish, lightweight, and extremely reliable pro scooter clamp! They start with 7000 series aircraft aluminum extruded, and then finish it up with CNC machining to final specs. The final step is to lay on the color via anodizing or powder coating to seal and strengthen the aluminum even further and protect from oxidation....also to make it look sick of course! The Double Clamp comes in the following colors: Black Anodized, White Powder Coat, Purple Anodized, Blue Anodized and Gunmetal Anodized. The Lucky Double Clamp is an oversized clamp that is designed to fit any 1 3/8” oversized pro scooter bars. They work great with the Lucky Voodoo bar, Prybar, 7Bar and Oversized Probar as well as any oversized bar on the market today.
