Kirschbaum Competition Tennis String Set

The Kirschbaum Competition is a high-performance co-polyester racquet string engineered for maximum durability without sacrificing control. Built specifically for aggressive baseliners who use open string pattern racquets or break strings frequently, it delivers consistent playability over an extended lifespan.

Available in 18 (1.20mm), 17 (1.25mm), and 16 (1.30mm) gauge.

Key Features

• Maximum Durability: Built to outlast standard co-polyesters, making it the right choice for string breakers and players with open pattern racquets who go through strings quickly.
• Exceptional Control: Keeps aggressive shots on target during fast baseline exchanges — confidence to swing fully without losing placement.
• Consistent Performance: Maintains reliable string bed response over time, so your racquet plays the same in your third session as it did in your first.
• Open Pattern Friendly: Engineered to hold up under the additional string movement and friction that open pattern racquets generate — lasting longer where standard strings wear out faster.
• Three Gauge Options: Choose 18 (1.20mm) for added feel and bite, 17 (1.25mm) for a balanced all-around response, or 16 (1.30mm) for maximum longevity if you break strings at the highest rate.
