The Black Code tennis string is a professional choice for competitive players seeking an uncompromised blend of resistance, control and comfort. It facilitates more flexibility thanks to the Thermocore design, and the unique pentagonal shape reinforces the structural integrity and provides maximised spin potential. Its a wonderful option for players with powerful strokes and a tendency to break strings easily since the Black Code is incredibly resilient and preserves the playing qualities for longer. Its the softest poly on the market, made in France and shipped in a 12m set.
