BLACK CODE string will give you spin and comfort.

We recommend a tension between 22 and 25 kg. Maximum tension: 32 kg.
The copolyester material used will generate control and resistance.

The pentagonal structure offers the ability to generate a lot of spin, allowing for extremely aggressive trajectories: deep, looping shots or short cross-court shots. A very effective arsenal on the court.

The technology for manufacturing monofilament is based on 3 essential points:

• The quality of the materials offered depends on the desired benefits.
• The Thermocore process. Specially developed by Tecnifibre for manufacturing polyester monofilaments to soften their natural stiffness. This requires a series of heating and cooling stages throughout the stringing process. This exclusive process reduces the polyester's stiffness, making it more comfortable to play with and less likely to cause injury.
• The final structure of the string can be round, pentagonal, or even square in order to increase the effects through friction.
