The racket used in Flex

Most of feathers on the market today, a tennis racket is the material mainly of carbon fiber, or by the high coefficient of graphite as the main material or auxiliary material, which contained a small amount of glass fiber is to adjust the flexibility and soft racket, hardness used.
