The XR-3 string is a special multifilament in the range since its construction with 3 larger diameter monofilaments provides a "crispy" touch that could be translated into a dry touch in addition to the qualities of comfort, resistance and power. . The particularity of this range is to present a wear indicator, which allows the player to change the string before the complete breakage. This witness is manifested by the significant fraying of the rope at the place of the bullet impact. Thanks to the assembly of several hundred microfilaments, impregnated to the heart in liquid polyurethane, Tecnifibre offers players the opportunity to gain in power and performance. Main material: Polyamide, polyurethane, silicone finish Recommended tension between 22 and 25 kg Maximum tension: 32 kg Not recommended for heavy rope breakers (< 10 hours of play). Rope made in France. PU 400: 400% elasticity for great comfort and dynamic performance. 3 Monocore PHP (Polymer High Performance): Specific construction with a larger diameter to increase durability and firmness. Polyamide fibers (544) Guarantees elasticity and touch of the ball when combined with PU 400. They provide tolerance in the event of off-center hits. SPL final coating Anti-abrasion coating for more resistance. BEST SELLER IN JAPAN The string is sold as the best all-around string. 3 Monocore PHP (Polymer High Performance): Specific construction with a larger diameter to increase durability and firmness. Polyamide fibers (544) Guarantees elasticity and touch of the ball when combined with PU 400.
