Tecnifibre X-One Biphase 130 is a premium multifilament tennis string designed for players who want exceptional comfort, power, and ball feel without switching to natural gut. Its construction combines polyamide fibers with polyurethane for a soft, elastic response that absorbs impact vibrations. Tecnifibre's Biphase treatment improves durability and tension maintenance, while the 1.30 mm diameter provides greater resistance to wear than thinner versions.
Intermediate to advanced players seeking a comfortable, powerful string with excellent touch and reliable performance. Particularly suitable for all-court players who value feel and responsiveness or want a premium alternative to natural gut.
