The Volkl Cyclone tennis string set features a special cog-shaped, monofilament design in order to achieve increased spin on each shot without blowing off control, durability and hindering the ball speed. It's a fantastic choice for players who want to take advantage of the spin potential to focus down opponents on the courts. The string is available in a 12m (40ft) set.
