The Torsion Balancer is a 0.8 g 3D-printed frame insert that cleans up off-center shot feel by damping torsional vibrations.
Stretched wide, late contact, fast hands: racket stays stable.
Vibrations disperse. The response becomes stable again — even outside the sweet spot.
0.8 grams of added mass, positioned with technical adhesive, for precise racquet balancing.
The shape spreads metamaterial along vibration paths, engineered to counter torsional waves where they travel.
Installed on the frame via adhesive strip, it modulates torsional vibrations and cleans sensation on off-center impacts.
That movement disturbs the hand and makes the racquet harder to control.
The Torsion Balancer brings order to that chaos.
It stabilizes the response and cleans the off-center sensation. The discomfort dissolves; the gesture returns to center.
It’s controlling how the frame vibrates.

The Torsion Balancer is the latest application of 3D printing and metamaterial engineering in tennis.
AMbelievable™ introduced this technology to the sport: now it becomes the first dynamic-response weighting system.
Not magic. Matter, made programmable.

The racquet doesn’t twist away on off-center shots anymore.
The sensation stays stable, even on running backhands.
I like that I can also use them just to fine-tune the balance.
Finally, a weight that also changes how I feel the racquet.
The difference on off-sweet-spot hits is clear. The racquet stays composed and that old discomfort is gone.
Moreover, Lower placements gave me a really pleasant effect, the racquet felt more maneuverable.
I tried placing them in different spots: overall the racquet vibrates less when I don’t hit the center.
