Kirschbaum Black Shark Tennis String Set

Description
The Kirschbaum Black Shark is an octagonal co-polyester racquet string built for baseliners who want maximum spin, precise control, and strong feel. Built on the same proven material as Pro Line Black, the eight-sided profile bites into the ball more aggressively than a round string — making it a natural choice for hybrid setups where spin and control on the mains is the priority.
Available in 17 (1.25mm) and 16 (1.30mm) gauge.
Key Features
- Octagonal Profile: The eight-sided shape grips the ball at contact and snaps back faster than round strings, generating more spin on topspin groundstrokes and serves without requiring swing changes.
- Maximum Spin Potential: Purpose-built for players who want to push spin to its limits — the shaped profile consistently outperforms round co-polyesters in spin generation.
- Precise Control and Feel: Delivers a connected, direct feel through the string bed, giving you clear feedback on shot placement during fast baseline exchanges.
- Pro Line Black Foundation: Based on the same co-polyester compound trusted by tournament players, bringing proven dynamic response and tension maintenance to a spin-focused construction.
- Ideal for Hybrid Setups: Pairs naturally with softer, more powerful strings on the crosses — giving you spin and control on mains while the cross adds comfort and power.
- Two Gauge Options: Choose 17 (1.25mm) for a livelier, more responsive feel, or 16 (1.30mm) for added durability if you break strings frequently.
