NANOMETRIC DR Unique Technology NANOMETRIC DR is a new carbon material developed by Yonex based on our unique NANOSCIENCE technology. Created from a material originally developed for next generation space aviation by Toray Industries, Inc., this marks the first time it has been used within the racquet industry. By combining firm shuttle hold and high repulsion, NANOMETRIC DR puts the DUORA into a class of its own. AERO Frame Smoother contours throughout the racquet head for less wind resistance and extra racquet speed. Compact Frame Faster Swing To balance the heavy racquet head, the frame has been made smaller to maintain the fast swing demanded by advanced players.By reducing the drag caused by air resistance, the head-heavy feeling is reduced and racquet handling speed is increased. 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. Solid Feel Core Cuts Vibration The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan. 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.
