Developed over 30 years ago, the ISOMETRICTM design increases the pure bounce area by 7%*. Compared to a conventional round frame, the square ISOMETRICTM racket generates 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.ROTATIONAL GENERATOR SYSTEM + 2G-NANOMESH NEO  - By applying counterbalance theory, the weight is carefully distributed across the grip end, upper frame and joint, enabling a smooth transition between powerful shots for fast, follow-up attacks. The innovative "2G-NANOMESH NEO" graphite used in the shaft, characterized by a fast flex and snapback, maximizes the power of the shot and increases the efficiency of the rotation generator system.STABILITY WEIGHT DISTRIBUTION - The additional weight distribution on the sides of the frame increases stability during the swing, resulting in maximum impact power. This also means that it allows for effective defense breakthroughs during cross-court attacks.ULTRA PE FIBER - The shaft is constructed of "Ultra PEF" - ultra polyethylene fiber - which is light enough to float on water, while being able to withstand enormous forces. These features allow for maximum shock absorption.ULTRA SLIM SHAFT - The thinnest ever and providing more power. Designed to cut through the air and generate quick power.Energy Boost CAP PLUS - A cap with a unique shape that maximizes shaft efficiency. The front allows the shaft to flex, while the arched sides stabilize the racket surface, preventing shaft twist.Power Assist Bumper - Included to force more, increased power by configuring the weight directed at the shuttlecock with a nylon bumper with added tungsten.
