New technology and structure combine with innovation to increase snapback and string movement, giving players access to the greatest spin in Yonex tennis history. For experienced and advanced players looking for a flexible racquet with precision and feel. ISOMETRIC – ISOMETRICTM technology continues to help the world's best players achieve global success. Developed over 30 years ago, the ISOMETRICTM design increases the pure hitting area by 7%*. Compared to a conventional round frame, the square ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRICTM provides greater control without sacrificing power. ISOMETRICTM is a trademark of Yonex CO., LTD. *Tested by Yonex.2G-NAMD™ FLEX FORCE - Aggressive, attacking spin with precise control achieved by a carbon nanotube structure that interconnects graphite fibers, reducing energy loss. Due to its elastic properties, the material flexes and provides a quick rebound. Namd™ is a technology developed by Nitta Co., Ltd. to evenly disperse carbon nanotubes throughout carbon fiber composites.SERVO FILTER - A transparent and flexible film placed between the graphite layers helps to bond them together while maintaining its elastic properties even after the molding process. This unique film absorbs unwanted vibrations, provides a finely tuned flex and snapback on every shot, delivering precise sensory feedback from ball to hand. SERVO FILTER is a vibration-absorbing film developed by Mitsubishi Chemical Group that has high bonding properties with graphite and stands out for both flexibility and durability.FLEXCON SYSTEM - The tapered and elongated shaft allows the shaft to flex comfortably, extending the time it takes to penetrate the ball, providing better feel and control. Flexibility is enhanced by “2G-Namd™ Flex Force”, a highly flexible graphite that provides 15%* more flexibility to the shaft of the racket. *Tested by Yonex.STIFF RACQUET FACE DESIGN- The frame uses more layers* of graphite to increase the stiffness of the racket head. 3% more stability to the racket head, providing better consistency of the ball trajectory. *Compared to the previous control-oriented version. Tested by Yonex.
