* Professional model wheel with fast and narrow speed profile * Mtech technology - fuses soft, 62A super resilient inner material with a hard, high wear-resistant outer layer * The inner softer layer allows the wheel to flatten like a radial tire during turns for added surface area to increase grip and control * Using quality, resilient urethane in the inner layer, the wheel then rebounds to provide energy to the harder, faster rolling outer layer * Durometer: 76A (Soft) * Sold individually
