Yonex Voltric Tour 5500 Badminton Racket (Unstrung, Black/Yellow) is made from a graphite shaft and its frame is made from both graphite and tungsten. It has a stiff flex. It has an isometric head frame. It has a Built-in T Joint that creates a durable and high-strength one-piece frame that is torque free. The new grommet system provides a more grommet hole. The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through, and the sharpest maneuverability.
