Tecnifibre NRG2

Unlike basic synthetic gut, the NRG2 uses a multifilament construction with over 1200 microfilaments and high-elasticity polyurethane. This design mimics the feel of natural gut, offering significantly more comfort and power while remaining more responsive and softer on your arm.

The S.P.L coating is an anti-abrasion treatment designed to reduce friction between the strings. This allows the main strings to slide and snap back into place more effectively, which helps generate spin and extends the overall life of the string bed.

The 1.18mm (18 gauge) offers the most power and feel but will break the fastest. The 1.24mm (17 gauge) is the most popular balance of playability and durability, while the 1.32mm (16 gauge) provides the longest lifespan for players who break strings frequently.

Yes, the NRG2 is widely considered one of the most arm-friendly multifilament strings on the market. Its soft, polyurethane-impregnated construction absorbs shock exceptionally well, making it a top recommendation for players looking to reduce vibration and impact stress.

Like most high-end multifilaments, the NRG2 is designed for performance over longevity. While it holds tension better than many budget options, you should expect a gradual drop-off in tension as the string fibers begin to fray and lose their elasticity over time.
