The racquet includes the addition of Graphene XT, Head's newest technology that enhances the maneuverability and feel over the previous models. You'll get the same great access to spin and control that you get in the adult version, Novak Djokovic's racquet of choice. With the heavy groundstrokes you'll be hitting with this one, be sure to remember to rip your shirt off just like Novak when you win that first junior Grand Slam! Available in a size (4 1/8) grip.
