Razor Spin Carbon Tennis String - Carbon / 16

The Tecnifibre Razor Spin Tennis String brings elite spin and tour-grade comfort to aggressive baseliners. The square cross-section bites into the ball at contact, generating higher rotation for more aggressive angles and a safer margin over the net. Polyurethane additives fused into the core absorb shock at impact, delivering a softer, more connected feel than traditional co-poly strings. High-modulus copolyester holds tension longer, so shot placement stays consistent from start to finish. Spin: The square cross-section grips the ball harder at impact, producing extra ball rotation that dips shots into the court and opens up wider angles. Comfort: Polyurethane additives fused into the core absorb impact shock, reducing arm fatigue compared to standard co-poly strings. String Type: Polyester Monofilament Composition: High Modulus Co-Polyester + Polyurethane Additives Construction: Square Cross-Section Gauge: 18 (1.15mm) / 17L (1.20mm) / 17 (1.25mm) / 16 (1.30mm) Length: 40 ft
