American runner-up Daniil Medvedev played this year with the new white tennis thong Tecnifibre Razor Code with superb tennis. Thermocore technology is used in the manufacturing process, polyurethane combined with polyester base material and is used at different temperatures during different construction phases, so the rope structure is soft. Thanks to Thermocore technology, the ATP Razor code is softer than traditional poly ropes. It has more strength and absorbs a lot of shock and vibration, providing a significantly improved playing ability. The Razor code stands for Tecnifiber-controlled polyester ropes and adapts very well to the T-shape and the new TF40 storage clubs. Tecnifibre ATP Razor Code is the true next generation of poly rope technology and its benefits are not only for hiking players, but also for all players looking for comfort, strength and durability. Try thinner gauges for more spin and a brighter feel or thicker gauges for a longer life.
