Très bon cordage

Ce cordage n'a rien à envier au RPM Blast ou au Black Code.

Cordage TA930

Bonne sensation avec ce cordage qui ressemble au Rpm blast. Un peu moins d’accroche mais un peu plus souple selon moi. Il est assez puissant et comme souvent sur du mono, la tension et le feeling s’estompent assez vite (10-12h de jeu). Le prix en bobine est super intéressant pour les gros casseurs

Additional Product Information

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 (20% loss within 3 hours of play).

When should you change your strings?

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 and stay bouncy longer.



Product testing

Our tests on the product features are conducted in a laboratory. The Resistance test checks the string's resistance to breaking. It is performed in the lab by the Canon Ball machine and checks the longevity of each string. The Power test is performed in our labs by a Charpy impact test machine. It verifies the energy absorbed by the product and its capacity to reproduce this speed on the ball.

Storage instructions

avoid extreme temperature changes and any moisture on the string. Do not leave your racket in the trunk of your car: the temperature can rise and fall dramatically!
