No. 1 Boost String

The Li‑Ning No. 1 Boost is a high‑performance badminton string engineered for advanced and professional players focusing on explosive repulsion and crisp, responsive feel. At a precise gauge of 0.66 mm, the string delivers maximum shuttlecock velocity with minimal swing force. Built using heat‑resistant, high‑intensity nano‑braided multifilament core and an equally durable outer nylon layer, it ensures even tension distribution and long-lasting structural integrity. The string is finished with a synthetic resin coating that enhances elasticity, smooth grip texture, and reduces vibration upon contact. It offers top-tier repulsion power rated 10/10 and a sharp hit sound, with balanced control (8/10), durability (8/10), and shock absorption (8/10) for complete playing experience.

Materials & Properties

• Gauge (Thickness): 0.66 mm (± 0.01 mm), ultra-thin for superior repulsion

• Core: Heat-resistant, nano‑braided multifilament yarn providing elasticity and tension retention

• Outer Layer: High‑intensity nylon with uniform tension distribution properties and vibration damping

• Coating: Elastic synthetic resin for smoother finish and enhanced shot feel

Performance Metrics

• Repulsion Power: 10/10 – ideal for fast smashes and quick clears

• Hitting Sound: 10/10 – clear, satisfying acoustic feedback

• Control: 8/10 – responsive touch for net and drop shots

• Durability: 8/10 – well-balanced for longevity given the ultra-thin gauge

• Shock Absorption: 8/10 – minimizes strain during long rallies

Length & Weight

• String Length per Reel: ~10 metres—covers a full string pattern for adult rackets

• Weight per Reel (approx.): ~25 g for packaging and usage reference in Malaysia

Usage Instructions

1. Use a professional stringing machine to tension the string between 25–28 lbs (≈ 11.3–12.7 kg) for optimal power and control balance.

2. String slowly, maintaining even tension increments to prevent snapping.

3. Always inspect the string bed before play—look for signs of wear such as fraying or notched grooves; replace if performance degrades.

4. Alternate between attacking strokes and net play to distribute string stress evenly.

5. After each session, clean the racket frame and store the racket in a non-twisted position—ideal storage is in a racket tube or cover at room temperature (~25 °C).

Precautions & Care Tips

• Avoid exceeding tension above 28 lbs, especially for this ultra-thin 0.66 mm gauge, as over‑tensioning increases snap risk.

• Keep the string away from direct sunlight or extreme heat, which can degrade resin coating and core fibres.

• Do not wash the string—moisture can weaken bonding and reduce tension retention.

• Replace the string immediately if hitting sound dulls, repulsion decreases, or visible wear occurs to maintain performance and prevent injury.

Recommended For

• Intermediate to professional-level players seeking maximum repulsion and sound clarity

• Players valuing fast shot execution and crisp feed‑back during rallies

• Suitable for gameplay in Malaysian indoor courts (25–30 °C, moderate humidity)

• Ideal for stringers offering premium string options in clubs or pro-level setups
