The Adidas Metalbone 3.4 2025 is Ale Galán's signature racket for the 2025 season. Diamond shape, Carbon Aluminized 16K, Soft Performance EVA core. Power 9/10, tolerance 8/10. An unusual combination for a power diamond: a strong attacking profile without the hard, punishing core typical of some power rackets.
The Metalbone 3.4 2025 weighs 345–360g (around 350g playing weight) and has a diamond shape with head-heavy balance. The profile is 38mm. The face is Carbon Aluminized 16K, aluminium-coated carbon for maximum spin transfer. The core is Soft Performance EVA (soft-medium). The frame has an octagonal structure for extra stability.
Metalbone 3.4 vs 3.3: The 3.4 is the direct successor. Updates: improved diamond mould (a more pronounced profile), Carbon Aluminized 16K surface. The core philosophy (Soft Performance EVA) and Weight & Balance System are retained.
Technologies:
- Carbon Aluminized 16K, aluminium-coated carbon for spin and durability
- Soft Performance EVA, a soft core with vibration absorption; higher tolerance than hard EVA alternatives
- Spin Blade, a surface pattern for spin production
- Smart Holes Curves, a nonlinear hole pattern for manoeuvrability and spin
- Weight & Balance System, up to 11.2g of additional weight can be added at predefined positions
- Octagonal Structure, an octagonal frame for stability on off-centre contact
The Weight & Balance System is a unique Adidas feature: you can adapt the racket to your playing style. More weight at the top gives more overhead power; lower in the frame gives more manoeuvrability.
Power is rated 9/10. Carbon Aluminized 16K combined with the head-heavy profile provides strong energy transfer on smashes and attacking shots. The high balance promotes ball acceleration and makes this racket particularly strong in net situations.
Spin is rated 9/10, the second highlight. The Carbon Aluminized coating creates a rough surface that provides more friction than polished carbon. Spin Blade reinforces this. For players winning points through spinning shots into corners, this is a relevant advantage.
Tolerance is rated 8/10, high for a power diamond. Most diamond rackets in this power segment score 6–7 for tolerance. The Soft Performance EVA core explains this: the material deforms slightly at impact and absorbs vibrations. Less punishment on off-centre contact than a hard core provides.
Manoeuvrability is rated 7/10, the logical downside of head-heavy balance. In quick net exchanges or wide defensive positions, the racket requires more guidance than an even or low-balance variant. This is the price of the attacking diamond construction.
Comfort is rated 8/10, above expectations for a power diamond. Together, the Soft EVA core and octagonal structure provide a softer contact feel and fewer vibrations than hard-core alternatives.
The Metalbone 3.4 2025 is the direct successor to the 3.3. Updates in the 3.4 generation include an improved mould (a more pronounced diamond profile) and Carbon Aluminized 16K surface. The core (Soft Performance EVA) and Weight & Balance System are retained.
For advanced and competitive attackers seeking power, spin and more tolerance than a typical hard power diamond offers. Thanks to the Soft EVA core, it is also accessible to players sensitive to stiff rackets.
The Adidas Weight & Balance System allows up to 11.2g of additional weight to be added at predefined positions in the frame. This lets you adjust balance to your playing style, with more weight at the top for more power, or lower in the frame for more manoeuvrability.

What you will notice as a player
The smash gets plenty of easy power; you do not need a full follow-through to put the ball away.
The sweet spot offers forgiveness: slightly imperfect contact loses little accuracy.
Comfortable in long matches: the racket cushions contact well, with little feedback in your arm.
At the net you react a little more slowly: the weight sits forward, so quick adjustments take more effort.
No pronounced weakness, but no single shot where the racket particularly stands out either.
Which shots are affected most?
| Situation | What will you notice? |
|---|---|
| Defense | Reasonable: a calm swing returns most balls off the glass. |
| Volley | Comfortable and stable; aiming is easy and you keep the ball low. |
| Bandeja | Very easy to control: the ball stays low and predictable, ideal for controlling the court. |
| Vibora | Very explosive: plenty of speed and bite, a natural shot for this racket. |
| Smash | Its strongest point: maximum power with little effort, sending the ball away like a rocket. |
| Block | The forward weight makes quick blocks more demanding than with an agile racket. |
| Off-center ball | Forgiving: just outside the sweet spot you lose little and the ball stays on course. |
