Badminton String BST 990 Pro Repulsion Golden

The BST 990 Pro Repulsion Golden is an ultra-thin, high-performance badminton string engineered for players who demand explosive power and crisp feedback in every shot. With a narrow gauge of 0.62 mm, the string excels under high tension (up to 28 lbs) by delivering maximal shuttle repulsion and a pleasing sharp sound on impact. Its lightweight multifilament core constructed from polyamide fibers bonded with resin (~60% polyamide / 40% resin) ensures superior elasticity, tension retention, and resilience. The thin profile makes it ideal for players seeking instantaneous shuttle response and fast-paced rallies—particularly suitable for Malaysian indoor courts (25–30 °C, moderate humidity). Its bright orange “golden” finish offers visual appeal and easy visual orientation during play.

Material & Build

• Gauge (Thickness): 0.62 mm—a super-thin profile for maximum repulsion and shot speed

• Core Construction: Polyamide-based multifilament core with resin coating for elasticity and tension stability

• Outer Finish: Smooth resin-treated surface—provides crisp feel and reduces abrasion during play

Performance Characteristics

• Repulsion Power: Outstanding—accelerates shuttle with minimal effort at high tension

• Hitting Sound: Bright, crisp acoustic response when contacting shuttlecock

• Control & Feel: Balanced control with responsive touch, especially in attacking strokes and net play

• Durability: Moderate—fine gauge reduces lifespan under prolonged use, so regular string replacement recommended

• Ideal Tension Range: Up to 28 lbs (~12.7 kg) tension for best repulsion and responsiveness

Length & Weight

• Length per reel: Approximately 10 metres—adequate for full stringing adult racket

• Weight per reel: Around 25 g (net)—lightweight for consistent handling and storage

Usage Instructions

1. Use a professional stringing machine to apply tension gradually, ideally between 26–28 lbs (≈ 11.8–12.7 kg) for optimal repulsion and sound.

2. String carefully in controlled increments to avoid deformation or snap risk.

3. Inspect string bed regularly—look for fraying, fuzz, or notches; replace at first sign of wear.

4. Alternate between high-impact strokes (smash/clear) and softer touch shots to minimize uneven wear.

5. After use, store racket in cover or tube, avoiding twisting; keep at ambient temperature (~25 °C).

Care & Precautions

• Avoid over-tensioning beyond 28 lbs, especially with ultra-fine gauge, as it increases breakage risk.

• Do not expose string to direct sunlight or damp environments, which can degrade coating and reduce tension retention.

• Never wash or wet the string; moisture can weaken resin and damage filament structure.

• Replace strings proactively if any dull sound, reduced repulsion, or visible damage is noticed to maintain performance and reduce injury risk.

Recommended For

• Advanced and professional players prioritising explosive repulsion, fast rally speed, and crisp contact feedback

• Players competing or training in Malaysian indoor court settings (room temperature ~25–30 °C, moderate humidity)

• Coaching centres, clubs, or stringing services offering premium performance string options
