Yonex Muse Tennis racket

The isometric design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC™ racquet generates a larger sweet spot by optimising the intersection of the main and cross strings. ISOMETRIC™ technology delivers greater control without sacrificing power. Uniform Impact Grommets A World First: Straight Grommet Holes on All Four Corners. Engineered exclusively by Yonex. Uniform impact on both on-centre and off-centre shots. These grommets merge two into one, extending both main and cross strings at the corners to increase string movement to make off centre shots more forgiving. Energy Flow Shaft A Forgiving Control Shaft Unexpected for such a thin shaft, this control shaft efficiently conducts energy with little stress. Built with an indented profile engineered to balance stiffness and flex.
