Victor Thruster K 550 has the perfect balance between power and control. The slight head-heavy balance and medium stiffness makes this racquet easy to use. • Power Box: The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension. CATAPULT STRUCTURE stores power and releases at smashing for maximum effect . POWER BOOST 9.75% The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life. 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
