The official racket for the Korea National Team The brand new Victor Superwave 37 uses Innver Wave and AeroDynamic design to give this racket a increased sweet spot and a greater power when hitting. E-TITANIUM- E.TITANIUM technology combines the titanium alloys that are generally used by the aerospace industry with carbon fiber, creating composite that is strong and stable. With E.TITANIUM technology applied on the frame head, a greater "moment of inertia" is created, making it more easy to launch a powerful smash. INNER WAVES- The INNER WAVES technology lengthens the string, with 5% extended sweetspot, significantly reduce shock, provides more maneuverability and face stability. AERO DYNAMIC- The elliptically-shaped section can decrease the air resistance, provide higher anti-torque, maximize control and vastly increase the speed of returning hit. NANO TEC- The NANO TEC technology works by evenly distributing nano-sized particles in the vacant space between carbon fiber bundles, this highly increases the overall stiffness of the carbon composite fibers, and reduces the distortion of the frame. SQUARE HEAD SHAPE- Offers 32% larger of sweet spot to the racket, increasing the accuracy of continual smash SERIAL TRACK SYSTEM- Gives additional T-Jointsupport giving the racket extra torsional stability. DIAMOND SECTION- The new Diamond shaped frame is a combination of traditional box frame with previously stability, power and control POWER-BOX FRAME- The power box frame uses a specially designed box frame to increases the rackets torsional stability and allows for higher stringing tension.THIS RACQUET IS 100% GENUINE.
