Tecnifibre X-One Biphase Tennis String is the ultimate multifilament string and provides the closest playability to natural gut of any synthetic string produced. Elastyl Fibers are used, giving 12% more power than the standard polyamide materials used in other synthetic strings. It features a unique technology that separates it from other strings in the Tecnifibre line, Fiber H2C, which involves a high temperature prestretching step to ensure greater tension maintenance. Improving on their PU Inside technology, this string features Trimerized PU, allowing for even more comfort and touch for that natural gut like feel.

X-One Biphase is renowned and appreciated for its power and comfort and the ability to retain these qualities over time.
