Overview

Tecnifibre NRG2 features 1,120 individual Elastyl fibers bonded with polyurethane resin offering 400% elasticity. This gives 12% more power than standard synthetic polyamide strings. The SPL (Silicon Pyrogene Lubritec) coating improves durability and resistance to notching. "Let's not mince words, Tecnifibre NRG2 is powerful" - ideal for players with slow to medium strokes still developing their swings. Playtesters raved about the soft, buttery feel. One of the best tennis strings for tennis elbow.
