Tecnifibre X-One Biphase String 17g. A premium multifilament string, X-One BiPhase delivers superb comfort, feel and a crisp response. A good choice for players seeking an arm friendly string without sacrificing power. Provides good tension maintenance too. About as gut-like as synthetics get. Offers a livelier feel, but with slightly less durability compared to the 16 gauge version and is a great choice to liven up a tight string pattern. The X-One Biphase string uses High Heat Capacity (H2C) fibers which allows the use of an innovative chemical treatment process called Trimerization. This new process increases the cohesion between chemical molecule links through extreme variations in temperature to result in ultimate dynamic efficiency (power) and exceptional feel. The new patented Biphasic process, with its visible marks on the string, extends string life by 20% and offers increased spin. Similar to its leading string, NRG2, the multifilament fibers within this string are immersed in polyurethane to provide shock absorption and optimum comfort. Tecnifibre Tennis String txob17r
