Tecnifibre X-One Biphase 17G Tennis String

Been using this string off and on as I went from 3.0 to 3.5 to 4.0 now. If you hit a little off then this string goes dead. But hit the sweet spot with the right swing and you can really drive the ball with power and spin (17s!) It is a little expensive but these work so well that you fall in love with your racquet all over again so it is worth it for a season. And its nice on the elbow and shoulder.

A good string for a player who likes the natural gut feeling. I applied to the main, with octagonal Black Code on the cross. Works well for me.

Really like the pop on these strings. They were recommended by a good friend who is a great player and I have been very happy with them.

This is a great string if you can afford it. It feels and wears like natural gut. It even frays like gut. Normally I would use this string in a hybrid combo with poly. This time I went full X-One. As the string wears and approaches breaking it loses its consistency. The string is not durable, but is excellent in power and control.

Great string for a passionate, recreational, senior player like me ~ have used it for many years! “Midwest” has the best rate and reliable shipping!
