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.
monofilament
For mono-filament strings, Decathlon recommends a tension of between 19 kg and 22 kg. To prevent injury, we strongly recommend against children under 15 using mono-filament strings. These strings are best for players who break strings in under 10 hours of play because they quickly lose their tension.
Multifilament
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.
Tecnifibre Razor Soft is a flexible monofilament that partially helps to prevent arm injuries.
When should you change your strings?
Your racket's performance depends 50% on your frame and 50% on your strings! Be sure to take the time to choose the right strings.
For players who break their strings a lot, change them as soon as they break.
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.
Decathlon's advice
You shouldn't tighten strings that have gone dead since their performance will have been lost. A loosely strung racket will let you play a more relaxed game, giving you more power without having to force it. Over time strings can become worn without breaking. They lose their elasticity and 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.
Comfort
Tecnifibre Razor Soft is a comfy, soft mono-filament string, which is quite rare, thanks to the addition of polyurethane additives in its manufacture.
