The Yonex BG 66 Ultimax (Black) is a gold-standard, high-repulsion badminton string favored globally by professional players and competitive tournament athletes. Constructed with an ultra-thin 0.65 mm gauge featuring High-Intensity Nylon Multifilament and a high-polymer outer wrap, BG66 Ultimax delivers an unbeatable combination of maximum shuttle speed, pin-point control, and a crisp medium feel. The sleek Black colorway provides a stealthy, understated aesthetic that complements any racquet frame design.
Performance Profile
- Repulsion Power (10/10): The slim 0.65 mm gauge produces maximum snapback, driving flat exchanges, clears, and smashes off the string bed with effortless speed.
- Hitting Sound (10/10): Delivers a crisp, high-pitched metallic crack on clean contact that adds rewarding acoustic feedback to offensive shots.
- Control & Touch (10/10): Exceptional string bed feedback and shuttle bite allow for pin-point accuracy on net hairpins, cross-court drops, and slices.
- Medium Hitting Feel (8/10): Offers a crisp yet cushioned response that balances stiff power transfer with comfortable shock absorption.
- Durability (6/10): Engineered purely for peak performance, shuttle velocity, and touch over longevity; requires more frequent restringing than thicker 0.68 mm–0.70 mm gauges.
Best Suited For
- Professional & Tournament Athletes: Ideal for competitive players who demand top-tier shuttle speed, precision, and acoustic feedback over long-term durability.
- Fast-Paced Attacking & Tactical Players: Designed for doubles specialists and aggressive singles players relying on quick drives, net control, and sudden smashes.
- Sleek & Low-Profile Aesthetic: Perfect for players seeking a stealthy black string bed that resists visible scuffs and pairs seamlessly with dark or contrast-colored racquet frames.
- Frequent Stringers & Club Players: The 200m reel yields roughly 20–22 restrings, significantly lowering overall stringing costs per racquet.
