Kirschbaum Max Power Rough 1.20 is a firm co-polyester tennis string designed for players who generate their own power and demand precise control. Its textured surface adds ball bite for spin-oriented play, while its low-powered response allows aggressive hitters to swing confidently. The thin 1.20 mm gauge enhances feel and spin potential compared with thicker gauges, although it offers less resistance to breakage.
Intermediate to advanced players with fast swing speeds who prioritize control, spin, and direct feedback. Particularly suited to aggressive baseliners who prefer a firm string bed and are willing to trade some durability and comfort for a thinner gauge.
