Kirschbaum Max Power Rough 1.25 is a firm co-polyester tennis string designed for aggressive players who prioritize control, spin, and consistent performance. Its textured surface increases ball bite for enhanced spin potential, while the low-powered response allows players to take full swings with confidence. The 1.25 mm diameter provides a balance of responsiveness and durability for competitive play.
Intermediate to advanced players with fast, full swings who generate their own power and want precise shot placement. Particularly suited for aggressive baseliners seeking a firm, controlled stringbed with additional spin potential.
