Description summary

Experience the pinnacle of string technology with the TECNIFIBRE X-One Biphase. Made in France, this best-selling multifilament string is engineered for top-tier playability, durability, and integrity. It delivers a dynamic blend of explosive power and supreme comfort, thanks to its unique combination of H²C and Elastyl® fibres. The exclusive Biphase process enhances spin and tension life, while a clever wear indicator frays to signal when it´s time to restring, preventing mid-match breaks. Get the renowned performance of natural gut with superior longevity

What our customers are saying about Tecnifibre X-One Biphase tennis single string

This arm-friendly multifilament tennis string is praised for its comfort, making it ideal for players with tennis elbow. It offers a superb blend of control and power, with a performance many consider the best in its class. Aesthetically, its natural color resembles gut strings. The main drawbacks are its high price and low durability, as the string is fragile and not recommended for powerful string breakers

José María

So far it is the best multifilament string I have tried. Its natural color is reminiscent of gut strings, aesthetically, it looks great on the racket. Fires very well. Strung at 22 kg. High price, is the only con.
