For experienced and advanced players looking for a flexible racquet with precision and feel. Specifications: - Head Size: 97 sq.in. - Weight: 310 g / 10.9 oz - Grip Size: 1 - 5 - Length: 27 in. - Width Range: 21 mm - 21 mm - 21 mm - Balance Point: 310 mm - Material: HM Graphite / 2G-Namd™ Flex Force / Servo Filter - Stringing Pattern: 16 x 19 - Stringing Advice: 45 - 60 lbs Technology: Isometric: - signature Yonex Technology Since 1980 Developed over 30 years ago, the Isometric™ design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC™ racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRIC™ technology delivers greater control without sacrificing power. 2g-namd™ Flex Force: - Aggressive, attacking spin for pinpoint control is achieved through a carbon nanotube structure that binds the graphite fibers together, which reduces energy loss. Due to its resilient properties, the material flexes and provides quick snapback. Namd™ is technology developed by Nitta Co., Ltd. to uniformly disperse carbon nanotubes in carbon fiber composites. Servo Filter: - A transparent and elastic film placed between graphite layers helps bond the layers while maintaining its elastic characteristics even after the molding process. This unique film absorbs unwanted vibrations, provides fine-tuned flex and snapback to each shot, delivering precise sensory feedback from the ball to the hand. Servo Filter is a vibration-absorbing film developed by the Mitsubishi Chemical Group, which has high bonding properties with graphite and excels in both flexibility and durability Flexcon System More Flexibility: - The tapered and elongated box frame allows the shaft to flex comfortably, extending the ball pocketing duration for more feel and control. The flexibility is enhanced by the ´´2G-Namd™ Flex Force,´´ a highly elastic graphite that enables 15%* more flexibility on the racquet shaft. Stiff Racquet Face Design For Improved Consistency: - The frame employs more layers of graphite to increase rigidity of the racquet face. 3% more stability on the racquet face, providing improved consistency in ball trajectory. Compared to previous controloriented racquet models.
