Description

The 4S string was designed to generate maximum spin.

Available in: Black.

Made of 100% co-polyester with a square structure.

We recommend a tension between 22 and 25 kg. Maximum tension: 32 kg

The co-polyester material used generates control and durability.

The square structure generates maximum spin for extremely aggressive trajectories: deep topspin balls or short crosscourt angles. The faster your swing, the more you amplify the spin!

Monofilament manufacturing technology is based on 3 key points:

The quality of the materials, selected according to the desired benefits.
The Thermocore process. Specially developed by Tecnifibre to manufacture polyester monofilaments and soften their natural stiffness. It requires a series of heating and cooling stages throughout the stretching of the string. This exclusive process lowers the stiffness of polyester, making it more pleasant to play with and less traumatic for the arm.
The final structure of the string, which can be round, pentagonal or even square to increase spin through friction.

As a leading string brand, Tecnifibre supplies polyester monofilaments to the world's best players, including Daniil Medvedev and Iga Swiatek. Designed, developed and produced in France, the Tecnifibre Monofilament is renowned and appreciated for its trajectory control, its ability to generate spin and its flexibility, thanks to an exclusive manufacturing process: Thermocore.

Our string factory, based in Wervicq-Sud (Northern France) for 175 years, has integrated a high-end production unit for monofilaments. Since 2008, it has specialized in the production of co-polyester monofilaments, known as the premium version of polyester because they combine several types of polyester in a single string.

Tecnifibre's mission is to unleash the potential of every player with products that combine high performance and unique elegance, all developed in the TECNILAB laboratory following one logic: Identify, Quantify, Solve.

FAQ

What kind of string should I choose for my tennis racquet?

Choosing the right string is almost as important as choosing the right racquet. It affects power, control, comfort, and spin.

Here’s how to choose:
Monofilament strings provide more control. They’re more durable and are chosen by players who frequently break their strings. They’re ideal for powerful players.

Multifilament strings, which are more elastic, provide power. Their flexibility is also known for its ability to absorb shock and thus prevent muscle soreness. This type of string is ideal for protecting young players from injury. It’s also well-suited for adult recreational or intermediate players.

What is the difference between monofilament and multifilament strings?

Monofilament strings provide more control. Because they are more durable, they are chosen by players who frequently break their strings.

Multifilament strings, which are more elastic, provide more power. Their flexibility is also known for its ability to absorb shock and thus prevent muscle soreness.

How do I choose the right gauge for my racquet string?

A thinner gauge makes the string more responsive, and the shot feels crisper.
A thicker gauge provides greater strength and, therefore, greater durability for your strings.
If you break your strings often, a thicker gauge is recommended.
