Muscle Power 2 frame allows exceptionally close contact between frame and string, enhancing the transfer of energy into every shot. Be noted that manufacturer's warranty will not apply for Yonex Muscle Power Series Badminton Rackets.
The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.
Muscle Power locates the string on rounded archways that eliminate stress-load and fatigue through contact friction. This construction creates total unity of the string and frame through closer and tighter contact.
