The Nano Cubic's offset design allows it to have the perfect shape for both inner and outer edges to skate a wider range of obstacles. Nano Cubics 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.
