Adidas Metalbone 3.4 2025
The Metalbone 3.4 2025 is Adidas’ ultimate power racket, designed and played by Ale Galán. A diamond shape, firm feel and the adjustable Weight & Balance system make it a weapon for advanced players who want to dominate with overheads and aggressive play.
Pros & Cons
Pros
- Elite-level power on smashes and overheads.
- Firm, direct, very connected feel.
- Weight & Balance system lets you fine-tune the racket to your game.
- Very stable on clean, centred contact.
Cons
- Low comfort for players with elbow or shoulder issues.
- Sweet spot is on the small side.
- Demands good technique and physical conditioning.
On-court performance
Back of the court
The diamond shape and head-heavy balance reward clean, prepared swings. Off-centre defensive shots lose depth quickly, so this isn’t a racket that bails you out when you’re rushed.
At the net
Blocks feel solid and volleys carry real weight. The firm face gives precise feedback when you’re picking out lines or feet.
Overheads (bandeja, víbora, smash)
This is what the Metalbone is built for: explosive smashes and heavy víboras. Few rackets in this range finish points as convincingly in the air.
Comfort & vibrations
Firm and direct, with limited vibration filtering. Players with a history of tennis elbow will feel it after long sessions — the Weight & Balance system helps, but doesn’t fully offset the stiffness.
Who it’s for / who should skip it
Good fit if…
- You’re an advanced or competitive player chasing maximum power.
- You want to fine-tune weight and balance to your game.
- You finish points at the net and in the air.
Skip it if…
- You have a history of elbow or shoulder trouble.
- You need a forgiving racket while your technique develops.
- You play mostly from the back and value control over power.

Verdict
The Metalbone 3.4 2025 doesn’t hide what it’s for: pure power. It feels firm, direct and extremely effective in the air, and the adjustable Weight & Balance system lets you dial in the feel without changing rackets.
It’s a demanding tool aimed at players who already hit with good technique — comfort and forgiveness are not the priority here, finishing points is. At 8.7, it’s one of the most complete power diamonds on the market for advanced players.
