Key Technologies

🔄 Rotational Generator System By applying counterbalance theory, weight is carefully distributed throughout the grip end, frame top, and joint — enabling smooth transitions between powerful shots for rapid, successive attacks. 

📐 ISOMETRIC Frame Developed over 30 years ago, the ISOMETRIC design increases the sweet spot by 7%. Compared to a conventional round frame, the square-shaped ISOMETRIC racket generates a larger sweet spot by optimizing the intersection of the main and cross strings, delivering greater control without sacrificing power.

⚡ AERO+BOX Frame Combines a solid hitting feel with a quick swing — ideal for fast-paced doubles rallies.

🔩 Power Assist Bumper A tungsten-infused nylon bumper attached to enforce heavier, increased power by configuring the weight directed into the shuttlecock.

🌀 Energy Boost Cap Maximizes shaft flex and control for explosive shots.
