Inspired by the Head Gravity racquets endorsed by Alexandar Zverev. For junior tennis player 4' 6" to 5', age 8 to 10. Bigger players should consider a 26" racquet. A very nice playing Carbon Fibre / Aluminum composite racquet. The Carbon Fibre uses Head's innovative IG Technology for more spin and power. Head Size: 100. Weight 10.3 oz. Grip Size 3-7/8. Very cool looking with different colors to resemble the adult Zverev racquet
