Platform score 7.8/10

The Metalbone 3.4 is adidas's flagship attacking racket: a diamond head, a high balance point and screw-in weights on the sides of the frame that let you shift weight towards the tip. The soft EVA core takes some sting out of hard hits. The rough face is built to grip the ball on viboras and kick serves. It is a racket for players who finish points overhead and have the technique to find a high sweet spot.

Who is this racket for?

Best for: Advanced players who finish points with smashes, bandejas and viboras.
Playing style: Power / Aggressive
Level: Advanced
Recommended for: Players who generate their own racket speed, live at the net and want to tune weight and balance with the screw system.
Not ideal for: Beginners, or anyone who wants maximum forgiveness on off-centre hits.

The diamond shape is clearest in the front view: the widest point sits up near the tip.

The balance point is shown in the edge view with the balance overlay.

What reviewers say

1 source summarisedChecked 7 Oct 2026

Reviewers treat the 3.4 as a finisher's racket. The 2025 update adds a longer handle, a faceted frame and a stiffening groove in the rail, and testers say overheads and attacking volleys come off with real sting and a direct, crisp response.

What testers like

Punch on smashes and attacking volleys
Direct, responsive feel
Longer handle adds leverage on overheads

Watch out for

Off-centre hits feel harsh
Less manoeuvrable than a teardrop
More shock to the arm than softer control rackets

Suits: Experienced attacking players, often on the left side, who finish points overhead.
Handle: Extended Power Extra Grip
Frame: Low Poly faceted design with Power Groove rail
Weights: Adjustable screws in the frame

Paladex’s read

A specialist. If you mostly finish points it rewards you; if you spend long rallies defending from the glass, a softer teardrop will be kinder to your arm and your error count.

Brand: adidas
Model: Metalbone 3.4
Collection: Ale Galán
Year: 2025
Shape: DiamondWidest high up near the tip, tapering in straight lines to the throat. The sweet spot sits high on the face. Maximum leverage for overheads and smashes. The smaller, higher sweet spot punishes off-centre hits, so it rewards good technique.
Weight: 345–360 gOn the light side: easy to swing for long matches and quick at the net, with less mass behind the ball.
Balance: High (head-heavy) · ≈ 272 mm (estimated)Where the weight is concentrated. Hits harder on smashes and volleys, but feels slower to swing and is more demanding on the shoulder and elbow. Higher balance generally favours power, lower balance usually improves maneuverability.
Thickness: 38 mmA full 38 mm profile (the regulation maximum) gives more stability and power.
Frame material: Carbon fibre, octagonal section
Face material: 16K aluminised carbon
Core: EVA Soft PerformanceComfortable and forgiving, with a bit more control on faster shots than a soft core.
Surface: 3D textureThe most bite on the ball, for players who rely on spin and effects.
Hardness: Medium-softLeans soft.
Sweet spot: High on the faceDerived from the shape class. The 3D zone is an illustration, not a measurement.
Grip & handle: Standard handle with overgrip

Our take

Sample editorialPaladex editorial (sample)

A tunable attacking weapon

Built for overheads first. The adjustable weights make it unusually personal, but it asks a lot of your technique.

The diamond head and high balance put mass where it helps a smash. The soft core keeps contact from feeling harsh, which makes the racket more livable than its attacking profile suggests. The weight screws are the standout: you can move the balance towards the tip for more punch, or leave it lighter for faster hands at the net. The trade-off is a high, compact sweet spot. Mishits low on the face lose pace quickly, and long defensive rallies from the back glass take more effort than with a teardrop.

Pros

Heavy hitting on smashes and viboras
Weight and balance can be tuned
Soft core feels comfortable for a power racket

Cons

High, compact sweet spot
Demanding in defence and for developing players

Verdict

Worth a shortlist spot for attacking advanced players. Look elsewhere if you mostly defend.

3D inspection notes

In the edge view, note the full 38 mm profile and the side weight screws. The front view shows how far the widest point sits towards the tip, which is the diamond's signature.
