Published on June 10, 2025 | By Team Tennis Ranch

As the inventors of the multifilament string, Tecnifibre has built its reputation on arm-friendly performance, consistent tension retention, and advanced feel. Whether you're a baseline grinder, serve-and-volley artist, or weekend warrior, Tecnifibre’s diverse string lineup has something tailored for your needs.

In this deep dive, we break down the entire Tecnifibre string range—from spin-focused co-polys to buttery soft multifilaments—so you can choose the best fit for your racquet, game, and arm.


Understanding Tecnifibre String Construction

Tecnifibre strings fall into three key material families, each offering distinct benefits:

  • Pure Multifilament: 1000+ filaments, over 40% polyurethane (PU) for ultimate comfort and shock absorption.
  • Mixed Construction: Multifilament core with added polyester strands for a firmer feel and more control.
  • Monofilament Co-Polyester: High-modulus polyester or thermocore-processed poly for control, spin, and durability.

This structure means Tecnifibre can offer strings for beginners needing softness, intermediates needing balance, and advanced players seeking surgical precision.
