Tennis Monofilament Spin String TA990 designed for expert players who break strings in under 10 hours of play looking for good spin, power and durability.

The Artengo TA990 1.27 monofilament string is perfect if you are looking for optimum spin and durability. It offers excellent power.
Abrasion resistance

Co-polyester greatly improves string durability.


The 1.27 mm diameter gauge produces great spin.


The polyester provides heavy, powerful strokes.

Directional control

The co-polyester material and 1.27 mm gauge offer provide good control.

Which tension is best?

Moderate tension (18 kg to 23 kg) offers more comfort, spin and power. The flip side is that you'll have less control and accuracy.
High tension (>23 kg) provides greater control and accuracy. It can, however, lead to tendinitis. You will also have less spin and power.

About monofilaments

For monofilament strings, Decathlon suggests a tension between 19 kg and 22 kg. We strongly recommend against using monofilament strings for children under 15 to avoid injury. These strings are best for players who break strings in under 10 hours of play because they quickly lose their tension.

About multifilaments

For multifilament strings, Decathlon recommends a maximum tension of 25 kg. These strings are recommended for people who are prone to tendinitis, youngsters, and people who don't break their strings often. Multifilament strings keep their tension very well.
For natural gut strings, Decathlon recommends a maximum tension of 23 kg. These strings offer superior comfort, feel and power. They also retain their tension extremely well.

When to change your strings

How your racket performs depends equally on your frame and strings. Be sure to take the time to choose the right strings.
For players who break their strings a lot: change them when you break them.
For people who rarely or never break strings, Decathlon recommends changing them as many times per year as you play per week. E.g. if you play once per week, change your strings once per year. If you play three times per week, change your strings three times per year.

Tips from Decathlon

You should not tighten a loosely strung racket as its performance will be affected. Looser strings will make your game more relaxed; if you aren't forcing things, you will have more power. Over time strings can become worn without breaking. They lose elasticity and their initial properties. The gauge (or diameter) also affects play. The smaller the gauge, the more power and spin you'll get. A larger gauge will give you stiffer strings with a heavier impact on your body.
