Yonex Exbolt 63 Badminton String

The Yonex Exbolt 63 (BGXB63) represents a massive leap forward in ultra-thin string technology. Historically, choosing a string below 0.65mm meant accepting that it would snap incredibly quickly. With the Exbolt series, Yonex introduced proprietary materials to shatter that compromise—delivering blazing-fast repulsion speed while holding onto an astonishing amount of durability for its thickness.

It is highly favored by fast-paced doubles players and counter-attacking singles players who thrive on midcourt drive speed, aggressive defense, and instantaneous reaction times.

Core Construction & Technology

The core innovation that makes the Exbolt 63 unique is the introduction of advanced, heavy-duty material coatings:

1. Forged Fiber Coating: This is the magic ingredient. Yonex bonded high-intermolecular molecules to create an outer wrap that has significantly higher heat resistance and tensile strength than traditional nylon. This prevents the ultra-thin strings from shearing and tearing easily during sliced shots or heavy friction.
2. Ultra-Thin 0.63 mm Gauge: One of the slimmest gauges in the entire Yonex catalogue. This microscopic thickness minimizes air resistance during your swing and maximizes elastic snapback.

Playing Characteristics

1. Lightning-Fast Repulsion (10/10): The standout feature. Because it is a 0.63mm string, the "hold time" on the racket face is exceptionally brief. The shuttlecock bounces off the string bed with instantaneous acceleration. This makes it lethal for flat, midcourt counter-drives where the fastest hands win the rally.
2. The Hitting Sound (10/10): Exbolt 63 produces a beautifully loud, piercing, and sharp metallic "ping." It sounds incredibly satisfying and immediately tells you when you've hit the exact center of the sweet spot.
3. Durability (7.5/10): For a 0.63mm string, the durability is remarkable. Thanks to the Forged Fiber, it lasts significantly longer than older ultra-thin strings like Yonex Aerosonic (0.61mm) or even classic BG66 Ultimax (0.65mm). However, it is still a thin performance string; it won't hold up to off-center framing or heavy mishits nearly as long as utility strings like BG65.
4. Control & Defense: Because it offers a crisp, highly responsive bounce, defensive blocks can be executed with minimal effort. You can absorb a heavy smash and easily redirect it deep into your opponent's rear court just by using the string's natural rebound energy.

Who is it for?

1. Speed & Doubles Specialists: If your game relies on rapid defense, quick net interceptions, and baseline-to-baseline drive duels.
2. Players Transitioning from Thicker Strings: If you want to experience the explosive speed of an ultra-thin professional string bed but are terrified of snapping your strings after just one or two sessions, Exbolt 63 is the ultimate entry point.
