VICTOR THRUSTER K300SP Badminton Racket suitable for beginners and up to intermediate players, the Thruster K 300SP has a flexible shaft. This makes the racquet easier to use especially when trying to generate power for your shots. Intermediate players can still enjoy using this badminton racquet as it can take high stringing tension up to 33lbs. For the more serious players, high tension gives you more control on your shots.
