Versatile performance on court
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.
Surprising solidity and control
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.
- Control 8/10 from an evolved multifilament
- Surprisingly solid impact
- Suitable for full-bed and hybrid setups
- Direct, communicative feel
Exceptional comfort and record durability
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.
- Comfort 9/10, among the highest in the range
- Resilience 10/10, record durability
- Consistent 8.5/10 tension maintenance
- Natural vibration absorption
Advanced construction technology
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.
The manufacturing processes
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.
Liquid Wax
The string is finished with a layer of wax. This treatment significantly extends its lifespan by reducing wear and making stringing easier.
Power Ribbons
Polypropylene and polyamide ribbons wound in several layers of thickness, overlapping and diametrically opposed, thus simulating the structure of a natural gut string.
Braided Core
Thanks to the "braided core" we achieve uniform elasticity and high strength.
