The Tecnifibre X-One Biphase Orange Color 18 Gauge Squash String is a multifilament string, the fibers 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.
Trimerized PU & H2C Fibres holds tension better for increased control.Biphase process for a 20% increase in durability. Elastyl fibre generates 12% more power (compared to standard polyamide PA).
