Yonex BG66 ULTIMAX - REEL

The Yonex BG66 Ultimax (200m Reel) is widely considered the gold standard for premium performance in the badminton world. It is the definitive choice for elite professionals, tournament competitors, and advanced players who demand lightning-fast repulsion power, precise control, and a loud, satisfying hitting sound.

The 200-meter bulk reel format yields roughly 20 to 22 racquet stringings. Given how thin this string is, buying it in bulk is highly recommended for regular competitors who need to re-string often.

Core Construction & Technology

The BG66 Ultimax achieves its world-class performance metrics by maximizing core density while minimizing overall thickness.

1. High-Intensity Nylon Multifilament Core: Yonex packs tightly bound, high-strength nylon filaments into a microscopic core. This provides substantially better tensile strength than basic nylon, allowing a razor-thin 0.65mm gauge to handle high tensions.
2. Special Braided High Polymer Nylon Outer Wrap: The outer layer features an intricate, high-density braided jacket that maximizes aerodynamic recovery. When the shuttle strikes the string bed, this outer wrap ensures an instantaneous snap-back effect.

Playing Characteristics

1. Elite "Lightning Speed" Repulsion: Because the string is only 0.65mm thick, it cuts through the air with minimal drag and flexes effortlessly upon impact. The immediate snap-back launches the shuttlecock with incredible speed, making it exceptional for defense, fast drives, and explosive smashes.
2. Balanced "Medium" Hitting Feel: Unlike the unforgiving rigidity of the BG80, the BG66 Ultimax has a medium feel. It offers a sweet spot that feels highly responsive without sending jarring, painful feedback into your wrist or elbow.
3. Piercing Acoustic Sound: The ultra-thin gauge produces an incredibly sharp, deafening metallic "pop" when hitting the sweet spot.
4. Laser-Accurate Control: The stringbed offers great pocketing feedback, giving you an exact sensation of where the shuttle is on the face of the racquet. This makes delicate drop shots, net tumbles, and tight deceptive cross-courts feel highly intuitive.

When Should You Buy the BG66 Ultimax Reel?

A full 200m reel of BG66 Ultimax is a premium investment, and you will get the most value out of it if:

1. You Prioritize Peak Performance Over Durability: Let's be completely candid—at 0.65mm, this string snaps relatively easily, especially if you mis-hit the shuttle near the frame. If you buy individual packs, the replacement costs add up fast. Buying the reel lowers your cost-per-stringing by roughly 30% to 40%.
2. You Compete in Tournaments Regularly: Tournament players need their stringbeds to perform perfectly. Having a reel allows you to string multiple racquets identically so that your backup racquet feels exactly like your primary setup if a string snaps mid-match.
3. You Prefer Arm Comfort But Still Want Power: If you want premium speed but strings like the BG80 give you arm fatigue or joint pain, the BG66 Ultimax’s shock absorption (rated 8/10) is the perfect upgrade.
4. You Run a Custom Stringing Business: This is arguably the most requested string by competitive club players. Keeping a reel on hand is a necessity for any stringer servicing intermediate-to-advanced clients.
