Racquet Technology Spin Boost+ Grommets: Dynamic set of spin-enhancing grommets work with the spin boost string tech to provide more power, spin and control. The grommets allow for more string movement, creating a 'bite' on the ball, thus generating more spin. The extra movement makes the string bed more forgiving, creating a larger sweet spot. Spin Boost String tech: Innovative enlargement of the string bed creates a more even power distribution and spin generation. This effect transfers more power to the top of the racquet where its needed for spin generation. V-Energy Shaft: Unique V Shape frame geometry in the shaft of the racquet enhances frame stability and power. Sonic Core(TM) made with InfinergyA(R) by BASF: Material placed in the 2 and 10 o'clock areas of the racquet to offer high rebound and reduced vibrations, helping you unleash game-winning shots at will.
