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. 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.

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.

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.
