Badminton string bst 990 black

The BST 990 Black is a high-powered badminton string engineered for players seeking explosive repulsion and a comfortable striking feel. With a gauge of 0.66 mm, the string delivers impressive shuttle acceleration under high tension, making it ideal for aggressive attacking styles. It is built with a polymer multifilament core combined with polyamide resin coating, designed to absorb impact smoothly and deliver consistent response during long rallies. Praised by users for its balance between speed and comfort, this string provides dynamic playability ideal for Malaysian indoor courts (approx. 25–30 °C and medium humidity. Its matte black finish gives a sleek premium look and helps with during-string tension alignment.

Materials & Properties

• Thickness (Gauge): 0.66 mm, offering high-speed repulsion and resilient rebound power

• Core: Polymer multifilament yarn designed for elasticity and uniform tension distribution

• Coating: Even polyamide–resin layer adds durability, vibration dampening, and smoother surface grip

Performance Metrics

• Repulsion Power: Very high—excellent for smash-heavy attacking play

• Hitting Feel: Softer than ultra-thin strings—striking feels smoother with manageable shock

• Control & Touch: Good balance enabling accurate net taps and drives

• Durability: Reasonable given the tension; rebuild recommended after regular heavy usage

• Sound: Sharp but not piercing—pleasant feedback at impact

Length & Weight

• String Length per Reel: ~10 metres—sufficient for most adult rackets

• Weight per Reel: ~25 g (approximate net weight)

Usage Instructions

1. Use a professional stringing machine with gradual tension increments. Ideal tension is in the 26–28 lbs (≈ 11.8–12.7 kg) range—maximising repulsion without compromising lifespan.

2. String slowly to avoid sudden snapping, ensuring consistent tension across the frame.

3. Inspect the string bed regularly for notches or fuzz; replace at first sign of wear to maintain performance.

4. Alternate between attacking strokes and touch play to extend the string life span.

5. After play, gently wipe down racket frame, avoid twisting the racket, and store in a cover at room temperature (~25 °C).

Precautions & Care Tips

• Avoid tension beyond 28 lbs to prevent breakage—especially critical with fine gauge strings.

• Protect from direct sunlight or humid conditions—both can weaken resin coating and shorten tension retention.

• Do not wet or wash the string—moisture can compromise structural integrity.

• Replace strings when acoustic feedback dulls, shuttle control lessens, or visible wear occurs to maintain performance and prevent arm strain.

Recommended For

• Intermediate to advanced players seeking powerful repulsion and balanced playability

• Players who prefer a responsive strike feel with controlled vibration

• Suitable for indoor badminton play in Malaysia’s typical ambient conditions (25–30 °C, moderate humidity)

• Clubs or stringers offering fast, powerful string options within a mid‑premium range
