Yonex Muscle Power 55 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. The Muscle Power series, with its unique frame construction, integrates the frame and the string like no other. The series is designed for players who go after fast movement and effortless power.
Muscle Power Frame: This technology enlarges the sweet spot of the racket, providing a higher level of control and power.
Isometric Head Shape: This technology expands the sweet spot vertically and horizontally, making it easier for players to hit shots accurately.
Carbon Graphite Shaft: This technology provides enhanced durability and stiffness, allowing for more power and accuracy in shots.
Light Weight: This technology reduces the overall weight of the racket, making it easier to maneuver and swing quickly.
T-Joint: This technology reinforces the area where the frame meets the shaft, increasing stability and reducing torque, which helps to improve accuracy.
