Tecnifibre Black Code 16 is a spin-oriented co-polyester tennis string designed for aggressive players who want precise control with a more comfortable response than traditional firm polyester strings. Its five-sided profile helps grip the ball for increased spin, while Thermocore technology provides greater flexibility and improved feel. The 1.28 mm diameter adds durability and a more controlled response compared to the thinner 17-gauge version.
Intermediate to advanced players with fast, full swings who generate their own power and rely on topspin for shot control. Particularly suited for aggressive baseliners who want a durable polyester string with strong spin potential and a less rigid feel.
