Magnetic Speed When the ball hits the strings, the racquet frame is naturally deformed, as both sides move together. As the equally polarized magnets move the sides to their original position more quickly, the returning power is accelerated and the ball is catapulted off the strings more powerfully. Two magnets but no gravity. Weight 10.2 Ounces unstrung 10.8 Ounces strung Length 27.25 Inches Tension 45 65 Lbs.
