For versatile players looking for a lightweight, flexible racket with precision and feel. ISOMETRIC - ISOMETRICTM technology continues to help the world's best players achieve global success. Developed over 30 years ago, ISOMETRICTM construction increases the pure hitting area by 7%*. Compared to a conventional round frame, the square ISOMETRICTM racket creates 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 for precise control achieved by a carbon nanotube structure that interconnects the 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 in 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 with every shot, delivering precise sensory feedback from the ball to the hand. SERVO FILTER is a vibration-absorbing film developed by Mitsubishi Chemical Group that has high bonding properties with graphite and is distinguished by both flexibility and durability.FLEXCON SYSTEM - A tapered and elongated shaft allows the shaft to flex comfortably, extending the time it takes to insert the ball, providing better feel and control. Flexibility is enhanced with “2G-Namd™ Flex Force”, a highly flexible graphite that provides 15%* more flexibility in the shaft of the racket. *Tested by Yonex.STIFF RACQUET FACE DESIGN - More layers* of graphite are used in the frame to increase the stiffness of the racket head. 3% more stability in the racket head, providing better consistency in ball trajectory. *Compared to the previous control-oriented version. Tested by Yonex.LOCK BOOSTER SYSTEM - New eyelet system features more holes in the upper part of the frame, as well as grooves that lock the string at impact and generate more spin and power.
