Kirschbaum Max Power Rough 1.30 is a firm co-polyester tennis string designed for aggressive players who prioritize precise control, spin, and durability. Its textured surface helps increase ball bite for enhanced spin potential, while its low-powered response allows players to take full swings without sacrificing accuracy. The thicker 1.30 mm diameter provides added durability and a more controlled feel compared to the thinner 1.25 mm version.
Intermediate to advanced players with fast, full swings who generate their own power and prefer a firm, controlled stringbed. Particularly suited for aggressive baseliners and frequent string breakers seeking durability, spin potential, and consistent performance.
