Kirschbaum Max Power Rough 1.30 is a firm co-polyester tennis string designed for powerful hitters who prioritize control, spin potential, and durability. Its textured surface helps increase ball bite for topspin and slice, while its low-powered response allows players to take aggressive swings with greater confidence. The thicker 1.30 mm gauge emphasizes resistance to breakage and a solid, direct feel, making it a practical choice for demanding competitive play.
Intermediate to advanced players with fast swing speeds who generate their own power and prefer a firm, controlled string bed. Particularly suited to aggressive baseliners and frequent string breakers who value durability over the added feel of thinner gauges.
