Double-row skates with PU wheels are durable, offer good drift performance, and are wear-resistant. The high-elastic PU wheel with a hardness of 82A balances wear resistance and smooth rolling, suitable for street use. Made from polyurethane polymer material, the wheels provide good anti-skid properties, wear resistance, and compression resistance. Four-wheel PU shock absorption ensures a more comfortable sliding experience. The thicker design offers a longer service life and safer high-speed rotation for improved comfort. High-elastic PU delivers excellent shock absorption and a wider ground contact surface, making it suitable for sliding on various road types and offering strong obstacle-passing ability.
