Yonex BG 66 Ultimax Badminton String

• The BG 66 Ultimax has a 0.65mm thin gauge and the perfect balance of maximum speed, control and durability, making it the best choice for the world's top players
• High repulsion
• Medium feeling
• The high-intensity nylon core gives 30% greater durability than normal nylon while a high-polymer nylon outer provides sharp feeling and high repulsion - exceptional all-round performance from an extra-fine string

Is the BG66 Ultimax worth ₹575?

The BG66 Ultimax is Yonex's most-used premium thin-gauge string at the international tour level — Lin Dan, Lee Chong Wei, Viktor Axelsen, and most current top-10 players have used it at some point. At ₹575 for a single 10m set it's not the cheapest string, but the cost-per-game is reasonable: the high-intensity nylon core gives roughly 30% more durability than standard nylon strings, so it lasts longer despite the thin 0.65mm gauge. If you want maximum repulsion (the "trampoline" snap that helps clears and smashes) with a sharp, crisp feel on impact, this is the string. If you string at 28+ lbs regularly or break strings often, consider the slightly thicker BG66 Force or Nanogy 95 instead — they last longer at the cost of some repulsion.

Which BG66 variant should I buy?

Yonex sells three strings in the BG66 family, and buyers searching just "BG66" or "BG 66" are often unsure which one fits. Here's the quick comparison:

• BG66 Ultimax (this product, 0.65mm): the thinnest, sharpest, highest-repulsion variant. The "flagship" BG66 used by most pro players. Best for advanced players wanting maximum power and feel.
• BG66 Force (0.65mm with reinforced core): same gauge but stronger, more durable. Better for hard hitters who break strings often.
• BG66 (legacy 0.66mm, also called Aerobite Boost in some markets): the original BG66, slightly thicker and softer feel. Older buyers familiar with the original line tend to prefer it.

For most intermediate-to-advanced Indian club players, BG66 Ultimax is the right pick — best balance of feel, repulsion, and durability for the price.

Common questions

What is the BG66 Ultimax tension range? Yonex rates BG66 Ultimax for 19 to 28 lbs on most rackets. SportsUncle strings up to 26 lbs in-house to avoid transit shock damage. For higher tensions, get the racket strung locally after delivery. The thin 0.65mm gauge is sensitive to clamp damage during stringing — use an experienced stringer.

How long does BG66 Ultimax last? For regular club play, typically 15-30 hours of play before notable tension loss or breakage. Heavy smashers and players stringing at higher tension see shorter life; controlled-game players see longer. Pros restring before every match because they need the exact tension — at club level you'll get clear value from a single set.

Is BG66 Ultimax the same as "Ultimatix"? Yes. "Ultimatix" is a common misspelling of "Ultimax" — Indian buyers sometimes type it that way because of the similar-sounding TCS employee portal. Same string, just spelled correctly as Ultimax.

What colours can I choose? Navy, Yellow, and Royal Blue are currently available — pick your colour at checkout. Yonex periodically releases other shades; check the dropdown for current stock.
