For versatile players looking for a lightweight racket that delivers electrifying power and superior comfort. SHOCKLESS GROMMET SYSTEM - The racket's grommets are integrated into the side and bottom of the frame to minimize muscle fatigue and provide a soft feel upon impact, protecting the wrist, forearm, and elbow by absorbing shock.DUAL SHUT SYSTEM - The Dual Shut System improves comfort and control on every shot. Shock-absorbing grommets in the lower part of the frame, combined with Quake Shut Gel located in the handle, eliminate 50% more vibrations.AERO SHAPE - Smooth frame contours reduce air resistance, increasing swing speed.O.P.S. - A system that provides excellent racket flexibility. It allows the ball to contact the strings twice as long, providing greater spin and control.LINER TECH - Holes in the grommets have been specially placed, allowing the strings to create a much wider active hitting area. The strings return to their original position much faster after impact, and their movement in the head adds more spin to the ball during shots.ISOMETRIC™ - The isometric shape of the racket head maximizes the area where the main and cross strings intersect, thus increasing the active hitting area even for off-center shots.
