The HDMX string provides a firm feel with maximum power thanks to its high-end materials.

Tecnifibre, the leading brand in strings, is innovating by proposing a brand new version of the hybrid, which generally combines 2 strands of 2 different materials.

This new technology combines 3 very complementary materials:

  • Polyester for control and durability
  • Polyamide for power
