Overview

Volkl Cyclone is a gear-shaped co-poly that has become one of the best value strings in tennis. The unique decagonal profile provides excellent ball bite for spin generation, while the firm construction offers predictable control. Playtesters found it surprisingly comfortable for a firm control string, and its exceptional price-to-performance ratio makes it a favorite among competitive players who break strings frequently.
