Power and energy are combined in the pre-strung SPARK TOUR TENNIS RACQUET for new tennis players.

1. ARCOREARCORE Technology is a spefically designed cross section in the shaft of the racquet to increase torsional stability for ultimate control and power.

2. METALLIX™Specially formulated crystalline metal alloy with a grain size 1000 times smaller than that of a typical metal creates a much stronger material. The Hall-Petch Effect states: smaller grains = stronger material. The result is a lighter, stronger and more powerful racquet.
