If you like a little more weight with a more even balance then the GRAPHENE XT EXTREME 165 is your weapon of choice. It features the same technologies and benefits as the 155 version, but has two main differences: With its slightly heavier weight, this racquet provides even more power. At the same time, the racquet has less head weight for enhanced maneuverability and quick swing speed so you can put the power to great use. Just like its 155 brother, it features the innovative Graphene XT Technology, which puts the weight of the racquet where you need it most for maximum swing speed. We also lengthened the main strings by creating molded tubes in the throat of the racquet. These Power Channels™ create high throat stiffness for an incredible increase in raw power. The optimized Delta Frame shape allows for the largest sweet spot maximizing the hitting zone, while the Power Stabilizer in the racquet's head guarantees stability so you can control the awesome power, even on off-center shots. The racquet features the new Adaptive String Pattern Technology (ASP), which allows you to customize your string pattern for power and string durability or extreme power and maximum feel. With its combination of more weight and enhanced maneuverability, the GRAPHENE XT EXTREME 165 provides incredible power and precision. It is a great weapon of choice for the true enthusiast and competitive player.
