The Vortex 100 is a unique frame that has been developed to optimize the spin potential and bamboozle your opponent with dipping, kicking groundstrokes. It’s distinctive geometry is design not only for looks but also for added benefits for the player. The inverse dual taper construction opens up the spin window for greater angle of attack and when combined with the 14x21 string pattern produces aggressive string movement and spin. This version packs a little more mass but still has a low swing weight to generate maximum racquet speed for more spin.
