Poly string technology is taken to a new level with the introduction of Tecnifibre Razor Code 1.25mm/17g Carbon. Thermocore Technology is used in the manufacturing process, combining polyurethane with the base polyester material and utilizing varying temperatures during the different stages of construction, allowing the matrix structure of the string to soften. Thanks to Thermocore Technology, Razor Code plays softer than traditional poly strings, has more power, and absorbs shock and vibration, providing much-improved dynamic playability. 17-gauge (1.25mm diameter) increases the spin potential and feel with a slight loss of durability.

Tecnifibre Razor Code is the true next generation of poly string technology, and its benefits are not just for tour-level players, but for all hard-hitting topspin players looking for more comfort, power, and durability.
