No me ha gustado

No sé si es por la tensión (me lo he puesto a 24-25), pero el que usaba habitualmente (RPM Blast) despide muchísimo más. Quizás debería ponerlo a un kilo menos, ya que el grosor es de 1.27, por 1.25 del RPM Blast. De todas formas, en general no he sentido mucho la bola con este cordaje

De momento muy contento y también el servicio de encordado (aunque tardó varios días por saturación de trabajo de la gente de san javier en murcia, tanta gente en verano y tan pocos chicos atendiendo) es genial.

Which tension is best?

Moderate tension (40 to 50 lbs.) offers more comfort, spin and power. The flip side is that you'll have less control and accuracy. High tension (>50 lbs.) 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 recommends a tension of between 42 and 49 lbs. 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 55 lbs. 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 51 lbs. These strings offer superior comfort, feel and power. They also retain their tension extremely well.

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 3 times per week, change your strings 3 times per year.

Tips from decathlon

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.



Product testing

Our tests on the products' advantages are performed in the lab: The Resistance test checks the string's resistance to breaking. This test is performed in the lab by the Canon Ball machine and lets us ensure that each cord has a long lifespan. The Strength test is performed in our labs by a Charpy impact test machine. This test verifies the energy absorbed by the product and its capacity to reproduce this speed on the ball.

Storage instructions

Avoid major temperature fluctuations. Do not leave your racket in the trunk of your car: the temperature can rise and fall dramatically!
