The BG66 ULTIMAX string features a super-fine diameter, which provides excellent repulsion power and a comfortable feel on contact with the shuttle. This means that you’ll be able to hit your shots with greater accuracy and power, without sacrificing control or touch.

One of the standout features of the YONEX BG66 ULTIMAX is its durability. The string is constructed using a high-intensity nylon multifilament core, which is then wrapped with a special braided high polymer nylon fibre. This construction ensures that the string is highly resistant to tension loss, which means that you won’t have to worry about restringing your racket as frequently as you might with other strings.

And let’s not forget about the eye-catching yellow colour of the YONEX BG66 ULTIMAX string. Not only does it look great, but it can also help to give you an edge on the court by making it easier to track the shuttle as it moves through the air.

In conclusion, if you’re a serious badminton player who wants to take your game to the next level, the YONEX BG66 ULTIMAX in yellow with a thickness of 0.65 is the perfect string for you. With its combination of power, control, and durability, you’ll be able to play your best game every time you step onto the court.
