Canted pucks allow the rider to relax their stance by bringing their knees inward toward each other, which promotes better alignment through the ankles, knees, and hips. This results in a more powerful and balanced position on top of the board. Includes 4 canted pucks, 4 puck gaskets, 2 in-line slot discs, 2 parallel slot discs, 8-M6x10.7mm pan head screws, and a puck alignment guide. Weight: 9.5oz / 272g
