Description

Tecnifibre X One Biphase black string

The Tecnifibre X One Biphase string is a top-of-the-range multifilament! It offers great responsiveness and comfort.

Its Biphase treatment gives it an exceptional tension hold for a multi-filament string.

Our string test Tecnifibre X One Biphase

During the first few hours of play, we appreciated the easy power of this string. With no effort at all, the ball is quickly off the string. On hard hits, this string is highly responsive, offering both feel and power.

However, control is not its best quality. You'll need to use the 1.30 gauge to gauge the power of this string.

Ball/string contact time is neither soft nor firm.

The big plus is tension hold! Thanks in particular to its biphase treatment, which gives it an exceptional tension hold.

It's also very comfortable! If you're prone to tennis elbow, this is the string for you.

As for spin, this Tecnifibre string is in the classic low medium range. As a result, it doesn't print much spin.

The 1.18 gauge will bring enormous power to your game! Whereas the 1.30 gauge will offer power under control.

Tension will play an important role, as the string is reactive to different tensions. That's why we advise you to set it at an average tension of 24 kilos on a headsize 645cm². Don't hesitate to ask us about your playing style and racket model.

WHO SHOULD USE THIS STRING?

We recommend the Tecnifibre X one Biphase string for players who want the best compromise between power, control and tension hold. But also players prone to tennis elbow who want a top-of-the-range string!

WHAT IS TECNIFIBRE X ONE BIPHASE DESIGNED FOR?

It is suitable for a wide range of players, from defenders to attackers. However, the power of this string is highly appreciated by defenders and counter-attackers.

Where does the Tecnifibre X One Biphase string fit in the Tecnifibre range?

It's somewhere between an NRG and a TGV in terms of power/control. The Tecnifibre NRG string will give you more power, while the TGV will give you more control.

Advantages:

  • Power
  • Comfort
  • Tension hold

    Cordage au top. Super agréable, précis et puissant ! Tendu à 22/21 kg sur Yonex Ezone 100, à voir dans le temps mais je le préfère au Babolat XALT
