RED X-ONE BIPHASE String Set

The X-ONE BIPHASE string gives you more comfort and feel.

It offers the same benefits as natural gut, without its drawbacks. It is therefore more durable and does not react to humidity.

Available in: Beige/Red/Black.

Made of more than 1,400 filaments based on an exclusive technical material:

50% Elastyl® fibers for maximum power.

50% H²C fibers for better tension maintenance.

The X-ONE BIPHASE string is made using a special process called "Biphase". It is an exclusive "pre-stretch" process that provides better tension maintenance. At the end of production, the string passes between 2 notched wheels turning in opposite directions to stretch it along its entire length. That is why it is the only string showing a kind of "notching", i.e. a natural variation between darker and lighter color. The X-one Biphase therefore offers a unique look compared with the other multifilaments in the range.

Multifilament manufacturing technology is based on 3 key points:

• The quality of the technical fibers, selected according to the desired benefits.
• The core impregnation of these fibers with liquid polyurethane (PU 400) guarantees exceptional comfort and power.

PU 400 is the highest grade of elasticity for PU used in racquet sports. That means 400% elasticity.

• The string finish with a slippery agent (SPL) makes it easier for the string to return automatically after ball impact (snapback) to promote spin

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

This string is designed for advanced players who are demanding in terms of comfort, feel and power.

Not recommended for heavy string breakers (< 10 hours of play).
