The X-ONE BIPHASE string will provide you with more comfort and feel.

It offers the same benefits as gut string but without its drawbacks. It will therefore be more durable and will not react to humidity.

Available in colours: natural /red / black.

Composed of over 1400 filaments made from a technical and exclusive material:

50% Elastyl® fibers for maximum power.

50% H²C fibers for better tension resistance.

The X-ONE BIPHASE string is manufactured using a special process called "Biphase." This exclusive pre-stretching process provides superior tension retention. At the end of the string's production, it passes between two toothed wheels that rotate in opposite directions to stretch the string along its entire length. This is why it's the only string that displays a "notching" effect, meaning a natural variation in color between darker and lighter shades. The X-ONE Biphase thus offers a unique visual appearance compared to other multifilaments in the range.

The technology for manufacturing Multifilament is based on 3 essential points:

• The quality of the technical fibers offered depends on the desired benefits.
• The impregnation of these fibers throughout with liquid polyurethane (PU 400) to guarantee exceptional comfort and power qualities.

PU 400 is the highest elasticity grade for PU used in racket sports. This means 400% elasticity.

• The stringing is finished with a slippery agent (SPL) to facilitate the automatic return of the string after ball impact (snap-back) to promote spin

We recommend a tension between 22 and 25 kg (maximum tension: 32 kg)

This string is intended for good level players who are demanding in terms of comfort, feel and power.

Not recommended for those who break strings frequently (< 10 hours of play).
