Black Knight Magnum Corona Squash Racquets with their medium stiff bridged frame are ideal racquets for those players looking to sharpen up their control while letting the racquet provide the power with an easier swing. The Magnum Corona features Ashaway SuperNick XL Ti string which will reduce the head weight slightly, for those looking for a heavier head balance. The Magnum models feature wide heads with large stringing surfaces, stiff frames and the Magnum bubble shaft design for better flex response and reduced vibration.
