About Tecnifibre
Tecnifibre was created in 1983 in France, pioneering polyurethane tennis strings with their revolutionary PU400 technology. They became the first string made 100% in France and remain so today. Known for their expertise in multifilament strings thanks to unique polyurethane technology offering 400% elasticity, Tecnifibre expanded into rackets in 2004 and became the official ATP World Tour supplier in 2013. Acquired by Lacoste in 2017, Tecnifibre continues to innovate - in 2024 they created the first t-shirt made from recycled tennis strings. Daniil Medvedev is their most prominent player.
