The Lucky Dub Clamp 1 3/8" is a stylish, lightweight, and extremely reliable oversized 1 3/8" double clamp. Hand designed by our riders and then computer engineered by our Lucky design team. We start with 6000 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!
