The Pure Aero represents a significant improvement over the previous generation of Aero rackets. A new aerodynamic frame enables the racket head to move more quickly and thereby increases ball speed, while new FSI spin technology provides enhanced lift. This racket responds superbly to players who seek power and optimal spin, like Rafael Nadal and Jo-Wilfried Tsonga.
