Octogonal shape ensures the strings bite the ball with maximum spin

New tennis strings for more spin

String of choice for Rafael Nadal and Andy Roddick, the Pro Hurricane Tour bring makes a big difference for ball spining.

A round smooth shape is naturally the best way to get tennis ball slipping on the string surface, so Babolat engineers design a new string with octogonal shape.It ensure a much better grip when the strings bit the ball, and the tennis players can give a more spin.
