VCORE is the 3D Vector Shaft technology which improves the stiffness of these rackets and reduces twisting. This gives them 20% more stability than the standard racket, leading to greater control and precision. New in for 2016 the revolutionary VCORE SV drives shots high over the net and ferociously down into the court--drastically reducing your opponent's reaction time. New Aero Fin Technology gives you more spin and more control.
