Orangatang Bushing Knuckle Purple One washer is missing, so I will include a different one. Made for quick transitions and smooth rebound, the Orangatang Knuckle is the ultimate high-energy bushing upgrade for carving, pumping, dancing, and freestyle longboarding. The Knuckle has a unique shape that is a cone shape with a touch of barrel shape. It has a gentle triangular shape, perfect for those who find regular cone types lack rebound but don't need the full rebound of barrel types. It has a moderate rebound and allows for very pleasant, deep turns. Perfect for carving, cruising, dancing, etc. Skateboard Longboard Bushing
