Tecnifibre 4S Set

The square structure will generate maximum spin, allowing for extremely aggressive trajectories: long, looping shots or short, cross-court shots. The faster the stroke, the more you'll amplify the spin!

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.
