Abstract: A manufacturing process for a bicycle hub includes steps of preparing dry carbon fiber fabric, covering around inner tube, placing in upper and lower molds, injecting adhesive into the upper and lower molds, and forming by heating and pressurizing. Because the manufacturing process uses tubular dry carbon fiber fabric to form a hub shell, the manufacturing process is simple and the produced hub has few defects. Thus, the production rate and product stability are enhanced.

Abstract: A new type of ball racket with bumper guard comprises a racket frame, a racket face, a shaft and a handle. The bumper guard is affixed on the curved section of the racket frame, which surrounds the ball racket face having a plurality of holes on the ball-hitting area, and then two sides of the frame converge to form the shaft. The end of the shaft has a handle. The design of the ball racket with bumper guard can protect the racket frame from many scratches and bumps against the wall or the ground during ball play. This not only can help extend the service life of a normal racket, but also reduces the chance of wrist injury for players.
