Pre-Stretch
Thanks to the "pre-stretch" of the core, the entire string minimises tension loss while at the same time allowing a lower stringing tension.
The innovation of the multifilament.
String Project Gold is a multifilament tennis string with marked solidity and control properties. With its gold colour, it offers a direct feel with unusual spin for a multifilament. Arm Friendly® certified with 9/10 comfort, 10/10 resilience and 8.5/10 tension maintenance.
String Project Gold offers absolute top-of-the-range resilience (10/10), ensuring exceptional durability for a multifilament. Comfort (9/10) is at the highest level thanks to Arm Friendly® certification and advanced multifilament construction. Control (8/10) is surprising for this category, while tension maintenance (8.5/10) ensures consistent performance over time.
Ratings measured in the laboratory by Pro-t-one (Eng. G. Medri), as are the technical specifications.
Gold is built with a sophisticated thermal-bonding process that joins an elastic polyester multifilament core to polyamide fibres. This advanced construction gives it solidity and control properties typical of monofilaments, while keeping the comfort and elasticity of multifilaments.

String Project Gold is built with a sophisticated thermal-bonding process that joins an elastic polyester multifilament core to polyamide fibres. This advanced construction gives Gold the solidity and control properties typical of monofilaments, while keeping the comfort and elasticity of multifilaments.

Thanks to the "pre-stretch" of the core, the entire string minimises tension loss while at the same time allowing a lower stringing tension.
The string is finished with a layer of wax. This treatment significantly extends its lifespan by reducing wear and making stringing easier.
We use “polypropylene” and “polyamide” ribbons wound in several layers of thickness so that they overlap and are diametrically opposed, thus simulating the structure of a “natural gut” string.
Thanks to the “braided core” we achieve uniform elasticity and high strength.
On court, Gold stands out for its versatility. In a full-bed setup it offers a solid impact that instils confidence in every shot. In a hybrid setup, its smooth texture and responsiveness generate unusual spin for a multifilament, with a dynamic response to the ball. Power is manageable, letting you meter force with precision. Despite its robustness, Gold offers remarkable comfort, absorbing vibrations and protecting the arm.

Gold offers solid impact and control (8/10) that are surprising for a multifilament. The thermal-bonding construction gives it properties typical of monofilaments, while keeping the comfort of its category.
With 9/10 comfort Arm Friendly® and 10/10 resilience, Gold offers maximum comfort with the highest durability in the range. Tension maintenance (8.5/10) keeps performance consistent over time.

String Project Gold is a multifilament tennis string built with a sophisticated thermal-bonding process. It offers solidity and control (8/10) that are surprising for a multifilament, with Arm Friendly® comfort (9/10) and top-of-the-range resilience (10/10).
Gold is a multifilament that, thanks to its thermal-bonding construction with a braided core and Power Ribbons, offers solidity and control close to a monofilament. Compared to monos, it guarantees superior comfort (9/10) and a softer feel, while keeping surprisingly direct playing properties.
The recommended tension range is between 18 and 23 kg. Thanks to the Pre-Stretch of the core, Gold minimises tension loss, letting you work even at lower tensions while keeping control.
Gold is available in two gauges: 1.25 mm (16L) for greater sensitivity and spin, and 1.30 mm (16) for greater durability and control.
Absolutely. Gold is Arm Friendly® certified with 9/10 comfort, one of the highest in the range. Its multifilament construction naturally absorbs vibrations, protecting the arm even during extended sessions.
Yes, Gold is very versatile in a hybrid setup. Paired with a monofilament, its smooth texture and responsiveness generate unusual spin for a multifilament, with a dynamic response to the ball.
