The essence of Babolat racquet technology is found in seven areas of the racket itself: GT (Graphite Tungsten) Carbon fibre materials, Y (collection of technologies in the yoke), Cortex System (anti vibration between handle and frame), Aero Modular (aerodynamic frame design), Smart Grip (handle grip shaped to fit the hand), XS Extra Sweetspot (integrated plastic that enlarges the racket sweetspot), PowerShaft (stabilizers and torque Reduction), and Woofer (frame and string integrate). Depending on which racquet you choose, you may have several of these Babolat technologies to help you play better.
