Yonex BG 66 Ultimax Badminton String , Black

The Yonex BG66 Ultimax in Black combines tour-level repulsion power, crisp tactile feedback, and maximum shuttle control with a sleek, stealthy visual finish. Constructed with an ultra-thin 0.65 mm gauge, it features a high-intensity nylon multifilament core surrounded by high-polymer braided outer fibers to deliver rapid shuttle launch speed and a sharp, high-pitched acoustic crack on impact.

Performance Profile

1. Repulsion Power (10/10): Maximum bounce speed and immediate energy transfer off the string bed due to the ultra-thin 0.65 mm gauge.
2. Hitting Sound (10/10): Produces a loud, high-pitched acoustic snap on clean center-face contact.
3. Control (10/10): Delivers precise shuttle bite and fine feedback for delicate net drops, hairpin placements, and sharp slices.
4. Shock Absorption (8/10): Medium-feeling string bed that comfortably disperses impact vibrations.
5. Durability (6/10): Lower wear resistance typical of ultra-thin gauge performance strings, requiring clean hitting technique to minimize premature snapping.

2. Attacking & Touch Playmakers: Players who rely on quick wrist snaps for steep smashes and precise control during net exchanges.
3. Acoustic Enthusiasts: Players who love a crisp, high-decibel popping sound on every clean hit.
4. Stealth & High-Contrast Cosmetics: The solid black finish offers a sleek, modern aesthetic that pairs seamlessly with any frame colorway or creates bold contrast with white grommets and bright grips.
