Wheel Diameter = 56mm / Wheel Width = 37mm Wheel Shape = Nano Cubic Wheel Formula = 97A Dragon Formula Outer Lip: Adds width & stability, makes Coconut Wheelies possible, climbs over coping and up onto curbs and up walls, and protects your axle nuts! Inner Lip: Leaves more truck exposed, grabs onto obstacles, and lock into grinds NanoCubics feature the same classic design advantages, of the legendary Cubic and MiniCubic, reconceived for today's skating, and utilizing our amazing Dragon Formula. The NanoCubic's offset design allows it to have the perfect shape for both inner and outer edges to skate a wider range of obstacles. NanoCubics are smaller, lighter, and offset, so their large outer edge rolls up curbs, walls, and over cracks, and it covers your axle and nuts. The inner edge locks onto rails but releases when you need to.
