Tecnifibre X-One Biphase (16-1.30mm) String Set:
Leading Edge Technology. Just like Tecnifibre’s leading string NRG2, the multifilament fibers in the Tecnifibre X-One Biphase (16-1.30mm) String Set are immersed in polyurethane to provide ultimate shock absorption and optimum comfort. According to Tecnifibre, the X-One Biphase string uses High Heat Capacity (H2C) fibers, which allows the use of a new chemical treatment process called Trimerization. Trimerization increases the compatibility between chemical molecule links through extreme variations in temperature to result in ultimate efficiency and exceptional feel. This new patented process, extends string life by 20% and offers increased spin. Playability similar to natural gut.
