The Head TI S6 tennis racket is a racket of superb overall performance and ability thanks to titanium design. Specially after Rotator Cuff Repair. Rotator cuff is a set of four different muscles located in the shoulder joint. These muscles form tendons and insert onto the shoulder bone. It affords the racket a level of maneuverability and control that is rarely seen with such a powerful piece of equipment. The Ti S6 gives you the power of a long racket without sacrificing agility and control.
