Tecnifibre X-One Biphase (16-1.30mm) String Set (Natural)

This string is great and provides a lot of feel and control. I typically string my rackets between 52-55 lbs and play tennis 3-5 times per week. Durability is great too.

Great balance of power and control. I use them on a Wilson Blade 104 v8 @ 50 lbs.Restring when they start to fray.

It feels amazing, but be prepared to restring often. The longest mine lasted was 4 hours. If you don’t hit with big spin or have arm issues it’s spectacular! If you have the time to string a lot and want the feeling of gut without the cost it’s great too.

Excelent and Awesome tennis string.Thanks!!!

Got my wife's racquet (Head Boom Team 2024) strung with Tecnifibre X-One Biphase (16-1.30mm) since she didn't like the stiff feel of the poly she had been using most recently (Yonex Polytour Rev 16G). Strung at 57 lbs. She liked the feel of these strings, but unfortunately broke a string (a cross string, interestingly) after only six and a half hours of play time - and the strings had apparently been fraying quite a bit before that. I restrung her backup racquet (identical to other) with the same string/same tension and some of the cross strings are already fraying after only ONE HOUR of play! (see attached photos) So not much hope that this set will last very long either... Honestly, it's not like we're 20-something professional players. We both played on our high school tennis teams and can give the ball a decent whack, but we're in our late 40's now. You'd think one of THE most expensive multifilament strings on the market would last a bit longer... Almost seems worthy of a warranty claim, to be honest. Would not recommend unless you only play occasionally or have a big restringing budget.

Lasts longer than others I have tried. Soft enough to be comfortable on my arm. These strings last me about 3 weeks with regular play before breaking.

Only lasted four hours play time while the ones I bought at local store lasted 3 months

I used to use Wilson NXT Control , the X-ONE is now my string of choice , excellent control and ultra soft plush feel. Takes away the stiffness from my Volkl Super G V1 pro , amazing string and very arm friendly!
