The Graphene XT Xenon is for players with very accurate shot placement. Its thin beam is a lot more aerodynamic for closer shots and better retrieval once the ball hugs the wall. The load redistribution of HEAD’s new Graphene XT technology combines speed and maneuverability without losing any accuracy. Graphene is Head’s newest breakthrough technology. This material has a breaking strength 200 times greater than steel, which makes it without equal substance for creating new HEAD racquet frames with exceptional properties. For the primary time, it allows an optimal redistribution of weight from the tip to grip. It enables a redistribution of weight in comparison to traditional frames, taking weight out of the middle and adding weight to the highest and bottom to permit players to generate more kinetic energy after they hit the ball. This design means that you can generate more power with less weight and not more effort. PLEASE NOTE: This racquet comes pre-strung from manufacturer.
