Tecnifibre NRG2 – What You Need to Know

Tecnifibre cracked the code on what a neutral arm friendly string should be with NRG. I was able to keep most balls in the court on my fastest swings and was shocked that I could. Obviously it’s a very comfortable string and knowing that I could still swing out on the ball was a pleasant surprise. Players that take full swings that develop arm pain later in life should definitely look to NRG first when making the switch from Poly. I think for players that take abbreviated strokes or hit super flat they might want to look elsewhere for a string that does a little more of the work. All in all I think it’s a great multifilament string for the modern swing style that takes tons of pressure off the arm compared to your classic polyesters. The biggest downside would be durability. The string started fraying in the first hour or two and broke after about 6 hours.

Tecnifibre NRG2 – What I Loved

Comfort and control are the name of the game in that order. The string doesn’t put any undue strain on the arm but still performs for a player with modern strokes. Probably wouldn’t work for Rafael Nadal but was fine for me. I also really liked the response on volleys and spin serves. Surprisingly I didn’t feel like I was getting a ton of power on my flat serves but I don’t really hit a lot of them so it didn’t really matter.

Tecnifibre NRG2 – What I Hated

The durability seems pretty low even for a multifilament despite the supposed 40% increase in durability according to Tecnifibres marketing team. The actual feel off the string bed when taking big swings also left a little something to be desired for me personally. I love the pop off the string bed but NRG is definitely on the more muted side.


Most multifilaments are on the pricier end and NRG is no exception. If you take big top spinny type strings you will burn through this string very quickly. But if you’re trying to protect your arm I’d say $19 a set is a small price to pay for your overall health. This string is constantly on sale when you buy multiple sets so you can definitely bring the overall price down if you keep an eye out.

Who this string IS for

Players with arm issues that still take a pretty big cut at the ball. Doubles players who are looking for good feel on volleys but also looking to take bigger swings on groundstrokes.

Who this string is NOT for

Players that crave that nice pop off the string bed will likely be looking elsewhere. I’m sure there are other arm friendly strings that make that a priority. Also if you need access to a lot of bite and spin this string won’t cut it. Players that want to leave their strings in the frame for months at a time will also need to seek out an alternative because this string will fray and break pretty quick if you hit with any kind of top spin or slice.

Final Verdict

Tecnifibre’s NRG2 deserves the love and popularity it has garnered over the years. It does what it’s supposed to do which is be arm friendly. But what really impressed me was the arm friendliness coupled with the controllable power. It’s a logical choice for players starting to feel the strain on the arm after years of playing with polyesters. Durability is low and the feel on hard shots leaves a little to be desired but overall great multifilament for the modern player.
