Tecnifibre NRG 2 SPL 16G Black Tennis String REEL (660FT)

Tecnifibre NRG2 is a multifilament tennis string built with the brand's PU Inside technology for added elasticity and an anti-abrasion coating for improved durability, while its fiber construction boosts power beyond standard polyamide strings. The 16-gauge (1.32mm) build is known for its arm-friendly comfort, making it a favorite among players with short to medium swing lengths who prioritize feel and power. Supplied on a 660-foot black reel, it provides enough string to service multiple racquets, well suited to stringers and clubs.
