ISOMETRIC Enlarged Sweet Spot ISOMETRICTM technology continues to help the world’s greatest players achieve global success. Developed over 30 years ago, the ISOMETRICTM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. ISOMETRICTM delivers greater control without sacrificing power. ISOMETRICTM is a Trademark of Yonex CO., LTD.*Tested by Yonex M40X A next-generation highly strong, yet elastic carbon fiber developed by Toray Industries, Inc. Sonic Flare System Max Acceleration The revolutionary new graphite material TORAYCAR M40X and SUPER HMG provide unrivalled power and stability for maximum shuttle acceleration. Ultra PE Fiber The shaft is constructed using ‘Ultra PEF’ – ultra poly ethylene fibre – which is light enough to float on water yet able to withstand immense forces. these characteristics allow for maximum shock absorption. Super Slim Shaft Reduced Air Resistance The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel. Energy Boost CAP Increased Control The new shape allows the shaft to flex, which ensures the maximum effect of “Namd[1](more flex and faster kick-back graphite material)” and stabilizes the racquet face by preventing the shaft twisting, increasing control New Built-in T-Joint The lightweight T-Joint increases stability of the shuttle on the strings, maximizing power and control.
