Tecnifibre Black Code 4S Tennis String

BLACK IS BACK at Tecnifibre! Black Code 4S, that is. Tecnifibre gives players a 15% more durable string than Black Code. It is a co-polyester with maximum spin potential helped by the square shape with sharp edges and holds tension as well as Razor Code. It offers 20% more power than Pro Red Code and excellent feel to boot!. Especially for a tough co-polyester string. Tecnifibre uses Thermocore Technology, which is a multi-stage heating process designed to soften the final structure and reduce harsh impact vibrations. Softening the blow, while keeping control and ball feel at their best. The comfort level is extremely high…amazingly so for a co-polyester! Any player wanting a highly durable co-polyester string with phenomenal control, feel, and spin-potential should definitely buy this string. Available in 16g for all around tournament play and in thinner 17g & 18g versions for really insane spin (but shorter string life). One amazing string!
