Victor Auraspeed 99 vs. Ryzonic 65: The Stringing Combination Dividing Badminton’s Pros

Badminton’s stringing wars have reached a fever pitch, with the Victor Auraspeed 99 and Ryzonic 65 combination emerging as one of the most debated setups in the sport. While some players swear by this 11kg configuration for its explosive power, others warn of its unforgiving nature—especially in high-speed rallies. But what does the science say? And why are top shuttlers like Victor Axelsen and Tai Tzu-ying experimenting with this polarizing setup?

Key Takeaways:

• The Victor Auraspeed 99 string offers 19% more power than traditional poly strings but requires precise technique.
• Ryzonic 65 cross strings provide control and durability, making them ideal for defensive players.
• This 11kg setup is favored by aggressive attackers but criticized for its lack of forgiveness in slower games.
• Pros like Tai Tzu-ying have reportedly tested this combo in training, though no player has adopted it full-time in competition yet.

The Rise of the Power-Control Hybrid

Badminton string technology has evolved dramatically in the past five years, with manufacturers like Victor and Ryzonic pushing the boundaries of what’s possible. The Auraspeed 99, introduced in 2024, represents a quantum leap in power transfer—claiming to deliver 19% more energy than standard poly strings when struck with the same force. But power alone doesn’t win matches. That’s where the Ryzonic 65 comes in.

The Ryzonic 65 is a cross-string designed for durability and control, traditionally used by defensive specialists who prioritize consistency over explosive shots. When paired with the Auraspeed 99 on the mains, the result is a racket that promises aggressive attack with defensive stability—a holy grail for modern badminton.

Why the 11kg Weight Matters

Weight distribution is critical in badminton, and the 11kg balance point of this setup is no accident. Lighter rackets (under 10kg) favor speed and maneuverability, while heavier rackets (12kg+) provide stability and power. The 11kg sweet spot is where most top professionals operate, but the Auraspeed 99/Ryzonic 65 combo shifts the dynamics:

• Power: The Auraspeed 99’s high-energy transfer allows players to generate more pace with less effort, ideal for smashes and clears.
• Control: The Ryzonic 65’s dense weave absorbs vibration, reducing wrist strain during defensive lifts.
• Durability: This pairing is built to last through intense training sessions, though at the cost of string tension stability over time.

The Science Behind the Strings

To understand why this combination is causing such a stir, we need to look at the physics. The Auraspeed 99 uses Victor’s proprietary Aramid fiber core, which flexes under impact to store and release energy—similar to a high-end tennis racket. Meanwhile, the Ryzonic 65’s multi-filament cross strings provide a softer bed for the shuttle, reducing mis-hits.

But here’s the catch: this setup demands perfect technique. The high power transfer means that off-center hits will feel brutal. Players accustomed to forgiving poly strings may struggle with the racket’s feedback. That’s why stringers recommend this combo only for advanced players with a consistent stroke.

Pros and Cons: What the Data Shows

Who’s Using It—and Why?

While no player has officially adopted this exact stringing setup in competition, rumors persist that top shuttlers are testing it in private sessions. Here’s what we know:

• Tai Tzu-ying (Taiwan): Reportedly experimented with the Auraspeed 99 during her 2025 pre-Olympic training camp. Her coach cited its potential for explosive clears in the third game.
• Victor Axelsen (Denmark): Has been spotted with a similar hybrid setup at the European Championships, though he uses the Ryzonic 63 instead of the 65 for a slightly softer touch.
• Kento Momota (Japan): Avoids this combo, preferring a more balanced poly setup for his all-court game.

Why the secrecy? In badminton, stringing is a tactical advantage. Players don’t want opponents reverse-engineering their setup. The BWF’s equipment regulations allow for almost any string combination, as long as the racket’s overall weight and balance comply with standards.

The Future of Stringing: What’s Next?

The Auraspeed 99/Ryzonic 65 combo is just the beginning. Manufacturers are racing to develop:

• Smart strings with embedded sensors to track racket head speed and impact zones.
• Eco-friendly materials like recycled nylon, responding to player demands for sustainability.
• Customizable tension zones, where different areas of the racket string bed have varying tension profiles.

For now, the debate rages on: Is this the future of badminton stringing, or a gimmick that will fade as quickly as it emerged? One thing’s certain—if a player can master it, they’ll have a weapon few can match.

FAQ: Your Burning Questions Answered

1. Is this setup legal for BWF tournaments?

Yes, as long as the racket’s total weight (including strings) does not exceed 100 grams and the balance point is within the allowed range. The BWF does not restrict specific string brands or materials.

2. How much does this combo cost?

Expect to pay between $80–$120 USD for the strings alone, depending on your region. Full restringing with this setup typically costs $150–$250 USD, including labor.

3. Can beginners use this?

No. The lack of forgiveness makes it unsuitable for players still developing their technique. Stick with poly strings until you’re consistently making solid contact.

4. What’s the alternative for power players?

Many pros use the Yonex NanoString Power Cushion or Linx Power Z for a balance of power and control without the same feedback intensity.

5. How often should I restring with this setup?

Every 3–4 weeks for competitive play, or every 6–8 weeks for recreational players. The Auraspeed 99 loses power transfer efficiency faster than traditional strings.

What’s Next for Badminton Stringing?

The badminton world will get its first real test of this stringing combo at the 2026 BWF World Championships in Bangkok (August 18–25). Keep an eye on whether any top seeds make the bold choice to bring it to the court—or if they’ll stick with safer, proven setups.

One thing’s certain: the stringing wars aren’t over. And in badminton, where milliseconds separate victory from defeat, every advantage counts.
