Sports Racquet
Provided herein are racquets, such as sports racquets. The racquets generally comprise a head frame with a curved side portion and a straight top portion and a curved bottom portion and handle affixed to the head frame between the top portion and portion. A plurality of openings is equally spaced through the head frame and a portion of the handle and a plurality of strings comprising a net pass through the openings. The length of the top rim of the head frame is greater than the bottom rim. The handle connects to the head frame at an angle of about 140 to 150.
RACKET
A racket 2 includes a frame 4, a grip 6, a grommet 10, and a string 12. The frame 4 includes a head 14, a first throat 16a, a second throat 16b, and a shaft 18. A maximum value of a thickness of the frame 4 is less than 26.0 mm. The racket 2 has an in-plane stiffness index Gi of greater than or equal to 5000 and less than or equal to 8000. The in-plane stiffness index Gi is a product of a top pressure stiffness value Git (kgf/cm) and a side pressure stiffness value Gis (kgf/cm). The racket 2 has an out-of-plane stiffness index Go of greater than or equal to 45000 and less than or equal to 60000. The out-of-plane stiffness index Go is a product of a throat stiffness value Gos (kgf/cm) and a ball-hitting face stiffness value Goh (kgf/cm).
