The Pro 255 Prestrung Tennis Racquet offer the stability of 100% graphite, but at a very light 9.0 ounces unstrung weight. For convenience, the Pro 255 comes prestrung and ready to play. With a large 100 square inch hitting surface, and a grippy 16x19 string pattern, the Pro 255 offers a good balance of power and spin. The constant 24 millimeter beam and firmer flex make this racquet incredibly stable for a reduced weight model.
