Gosen GOSEN Badminton Racket CUSTOMEDGE PS FLEX-A 4U6 Full EVA Technology A technology that fully fills the frame and shaft with EVA (foaming agent). This improves the feel of holding the shuttlecock at impact and provides dramatic repulsion due to increased resilience. Conventionally used only in the frame, this time it is also incorporated into the shaft, and by expanding it from the inside to the outside with EVA, molding close to a new circle becomes possible. Furthermore, the design has fewer voids (air layers), and the reduction of air layers within the carbon sheet also adds a new technology that absorbs vibration. Weight Balancer A custom part that can be attached to any location on the frame. The swing weight can be changed depending on the attachment position. 【Example of Attachment Positions】 Attach to the top of the frame Attach to the bottom of the frame → Top Heavy Even
