The length of the racquet has been optimized to allow easier acceleration of the racquet head and promote speed and spin. The new ergonomics of the frame with reinforced sections, a 645cm² headsize and the 16x19 string pattern give it maximum power. Isoflex technology, a new design of progressive sections, stiffer on the short strings and softer on the long strings for maximized flexibility of the string pattern, allows you to maintain speed and precision on off-center hits. The Superlight Cap, a thin bumper integrated into the frame, makes the racquet head lighter for better handling.
