Tecnifibre X-One Biphase (Set)

X-One Biphase string uses High Heat Capacity (H2C) fibers, which allows the use of an innovative chemical treatment process called Trimerization. This 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 Biphasic process, with its visible marks on the string, extends string life by 20% and offers increased spin.
