Tecnifibre Black Code 4S is Tecnifibre's squared-shaped low-power co-poly designed to give players maximum spin potential. Utilizing a co-polyester core, this string possesses excellent durability with greatly enhanced tension maintenance and feel. Black Code 4S features a square profile, helpful for generating more spin as the string bites into the ball better. The string uses Tecnifibre`s exclusive ThermoCore technology which serves two primary purposes. String-to-string friction is greatly reduced, enhancing durability and further promoting spin and ease of stringing. The ThermoCore technology also gives the string greater flexibility for more power and a softer feel.
