- Tension 18–23 kg
Playing profile
String Project Gold offers top-level comfort (9/10), which comes from its multifilament construction: Gold is Arm Friendly®. It is also stable on the string bed, with control (8/10) that is high for a multifilament. Resilience (10/10) is the highest in the range and tension maintenance (8.5/10) ensures consistent performance over time.

Versatile performance on court
On court, Gold stands out for its versatility. In a full-bed setup it offers a comfortable, stable 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, and comfort remains remarkable thanks to vibration absorption.
Stability on the string bed
Gold offers stability on the string bed and control (8/10) that is high for a multifilament. The thermal-bonding construction gives it a composed response, while keeping the comfort of its category.
- Control 8/10 from an evolved multifilament
- Stability on the string bed
- Suitable for full-bed and hybrid setups
- Composed, predictable response
Maximum comfort and elasticity
With 9/10 comfort Arm Friendly® and 10/10 resilience, Gold offers maximum comfort and elasticity that lasts over time. Tension maintenance (8.5/10) means it holds its tension for a long time.

Advanced construction technology
String Project Gold is built with a thermal-bonding process that joins polyamide and polypropylene fibres, wrapped in overlapping layers that simulate the structure of a natural gut string. This construction gives Gold its stability, while keeping the comfort and elasticity of multifilaments.
The manufacturing processes
Pre-Stretch
The pre-stretch of the core minimises tension loss and allows stringing at lower tensions.
Liquid Wax
The string is finished with a layer of wax, which reduces wear, significantly extends its lifespan and makes stringing easier.
Power Ribbons
Polypropylene and polyamide ribbons, wound in several overlapping, diametrically opposed layers, simulate the structure of a natural gut string.
Braided Core
The braided core gives the string uniform elasticity and high strength.
