Tecnifibre Triax

Tecnifibre describes Triax as a multifilament construction incorporating co-polyester. That differs from installing two separate strings as mains and crosses. The precisely identified TWU test sample is 1.33 mm.

Laboratory measurements

Lower stiffness means less resistance to deformation in this test. Tension loss is measured under a laboratory protocol, not a prediction of playing hours. Spin potential is a friction-based ratio, not ball RPM.

The test tension is not a stringing recommendation. Compare the same gauge and test conditions; the racquet, stroke and stringing method also affect the result on court. On the source page, select All in the material filter to see results for every material.

Read the construction fields beyond the page title

The manufacturer page title contains monofilament, while its description, features and Strings type identify a multifilament. It also describes co-polyester and high-density polyurethane. One conflicting title word should not overwrite the detailed construction information.

Multiple materials within one finished string are different from a hybrid installation using separate products in the mains and crosses. A full bed of Triax still contains its internal material combination.

Separate the 1.33 mm test from the 1.28 mm retail page

TWU’s Triax 16 (1.33) records 161.7 lb/in stiffness, 25.0% loss and a 5.8 spin-potential ratio at 51 lb and Fast speed. The linked manufacturer page displays 1.28 mm, so these figures must not be presented as a 1.28 mm test.

The verified scope is one identified 1.33 mm sample. Claims of combining benefits from different string families cannot supply unmeasured stiffness for another gauge or a guaranteed durability multiple.

The question depends on what you are replacing

A polyester user may examine depth from short defensive preparation and changes in firmness. A multifilament user may examine wear and whether familiar length remains repeatable.

In both cases, compare against a documented setup in a familiar frame. An intermediate product description cannot establish universal suitability without knowing the response being changed.

Use wear records to examine durability claims

Record intersection notches, surface damage and hitting time, and compare the location where the previous string failed. Also track trajectory and the mains’ return after displacement.

The 25.0% laboratory loss is not a proportion of playing time. Combining construction information with observed wear helps identify what to change in the next installation.

Racquets to compare

Numbers are suggested only when the maker publishes a tension range.
