Kirschbaum Max Power Rough 1.25 is a firm co-polyester tennis string developed for players who generate their own pace and demand precise control. Its textured surface adds ball bite to support topspin and slice, while its low-powered response allows aggressive hitters to swing confidently without sacrificing accuracy. The 1.25 mm gauge offers a practical balance of spin potential, direct feel, and durability for competitive play.
Intermediate to advanced players with fast swing speeds who prioritize control, spin, and a firm string bed. Particularly suited to aggressive baseliners who prefer direct feedback and are comfortable with the firmer feel of performance polyester strings.
