Designed for exceptional spin, Solinco Barb Wire 1.30 features the same square profile geometry as the popular Tour Bite. In order to offer even greater spin potential, the string is subjected to an axially twisting procedure, increasing the surface roughness for increased grip. The result is that Barb Wire is the most spin friendly string in the line, while offering some interesting playing characteristics. The unique co-polyester construction combines excellent durability and resilience for power. Best suited to hard-hitting baseline players looking for maximum spin and durability without sacrificing all feel and power. Construction: Co-polyester monofilament Color: Black Gauge: 1.30 mm (16g) Length: 656 ft / 200m Need help selecting a string? Check out our Choosing The Right Tennis String guide for more assistance.
