The shaft of this badminton racket is made of Ultra High Modulus Graphite + Nano Fortify and 7.0 Shaft .The isometric head shape provides a large surface area for the shots and distributes equal amount of force across the frame.The frame of this badminton racquet is made of multi-layer graphene and nano resin.With a string tension of 28 lbs-30 lbs, it has an enhanced accuracy and power of shot. The balance of this racquet is head heavy and has medium stiffness, enabling better movement. The frame is designed in a way it has isometric shape, which adds to the stiffness of the racquet. The grip handle is firm and steady, providing players with extra comfort. Victor Badminton Racket Technology : POWER BOX : The box-shaped design effectively increases the stability and anti-torque , can stand higher string tension. . 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. . SEVEN SIX 76 : The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life. . CSR COMBINATION : Core shell rubber is used to cover the epoxy resins to build resilience and protection. .
