Poly string technology is taken to a new level with the introduction of Tecnifibre ATP Razor Code 1.25mm/17g Carbon Reel. Razor Code is the string of choice of former ATP player Janko Tipsarevic, and brings a new feel to monofilament strings. 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, ATP 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 spin potential and feel with a slight loss of durability.
Tecnifibre ATP Razor Code is the true €œnext 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.
Construction: Monfilament co-polymer with Thermocore Technology
Color: Carbon
Gauge: 1.25 mm / 17g
Length: 200 m / 660 €™
