Ensures a sturdier and more flexible frame, while the increased shaft flex maximizes power. The ISOMETRICTM technology continues to assist the greatest players in achieving global success. Developed over 30 years ago, the ISOMETRICTM design increases the sweet spot by 7%. Compared to a traditional round frame, an ISOMETRICTM square-shaped racket generates a wider hitting area by optimizing the intersection of the main and cross strings. ISOMETRICTM offers better control without sacrificing power. ISOMETRICTM is a registered trademark of Yonex CO, LTD. By applying counterweight theory, weight is distributed across the end of the handle, the top of the frame, and the joint for maximum control. The transition to the next shot can be done smoothly, with rapid succession.
