The X-ONE BIPHASE string is the best performing string in this range on the three criteria of playability, durability and integrity. The particularity of this range is to present a wear indicator, which allows the player to change the string before the complete breakage. This indicator is manifested by the significant fraying of the string at the point of impact of the ball. Tecnifibre is the leading brand in strings and has built its success on the design and production in France of the first multifilament strings. These strings are renowned and appreciated for their power, their comfort and their strong capacity to preserve their qualities over time. Colour : natural Main material: Polyamide, polyurethane, silicone finish Recommended tension between 22 and 25 kg Maximum tension: 32 kg Not recommended for heavy string breakers (< 10 hours of play). String made in France. PU 400: 400% elasticity for great comfort and dynamic performance. Elastyl® fibres (50%): +12% elasticity compared to a standard PA. Provides enormous elasticity for maximum power. H²C Fibres (50%): Maximises performance with high temperature fibres for better tensile strength. Biphase Process: Exclusive "pre-stretch" process to provide better tensile strength and life. Visible and noticeable on the string, it increases the spin. Best seller worldwide The performance of the casing without the defects of the casing. Learn More

The ultimate in multifilament strings, providing the closest playability to natural gut, giving players maximum power, feel, and comfort. Elastyl Fibers are used, giving 12% more power than the standard polyamide materials used in other synthetic strings. Improving on their PU Inside technology, this string features Trimerized PU, allowing for even more comfort and touch for that natural gut like feel. Many years of research have led to the Biphase process, a production process that increases string durability by 20%, letting players experience the benefits of this string for even longer.

Triax, the first co-polyester multifilament Tecnifibre's first multi-filament co-polyester tennis string, Triax, offers an answer to the following question: How can we guarantee that high performance players will be able to maintain a consistent and deep ball length throughout their match, while at the same time providing a firm feel to generate spin and a very good durability? This string offers: A superior level of durability, thanks to the Co-polyester material used for the first time in a multifilament. A higher level of arm protection, thanks to the use of Polyurethane (HD) which is 100% flexible. A superior level of spin, directly related to the highest level of firmness in a multifilament. Welcome to Triax! String made in France. Co-Polyester (T.P.I): Provides an extra firm feel and increased durability. Polyamide material selection: generates tolerance for off-centre hits. PU HD: 100% elasticity to match the stiffness of polyester. It will provide extra comfort. ? S.P.L Coating: Anti-abrasion coating for more resistance. It also guarantees good slipperiness to ensure the "snap back" which provides more lift. MOST RECENT PRODUCT ON THE MARKET Developed in 2019, it benefits from the latest improvements and factory settings. Learn More
