Our Verdict
The Metalbone 3.4 is Adidas's most complete attacking racket for the 2025 season and a genuine step forward from its predecessor. The 16K aluminised carbon faces deliver exceptional rigidity and exit speed, while the EVA Soft Performance core prevents the feel from becoming harsh on well-struck balls. The Power Groove system and Octagonal Structure work together to channel energy efficiently, and the Smart Holes Curve meaningfully expands the sweet spot for a diamond racket at this stiffness level. This is the racket for advanced and competitive players who dominate from the net, generate pace and spin effect as primary weapons, and want a tool that can be fine-tuned to their game via the Weight & Balance System.
Metalbone 3.4
The Metalbone 3.4 is a professional-grade attacking racket built for advanced players who want explosive ball output, heavy spin, and customisable balance in a single tool. The 16K aluminised carbon faces and EVA Soft Performance core push this firmly into offensive territory without entirely sacrificing feel.
- Attacking players will notice significantly more exit pace and spin effect than most rackets at this level, driven by the combination of 16K aluminised carbon faces and the Smart Holes Curve arrangement that bites into the ball on contact.
- The Weight & Balance System is genuinely useful — being able to tune the balance point to suit your position or style is a rare feature at this price point and makes the racket more versatile across different match situations.
- Even under pressure at the net, shots feel crisp and well-directed rather than uncontrolled, which is a notable achievement for a high-balance diamond that pushes this hard for power.
- Players at intermediate level or below, or anyone who relies on feel and touch from the back court, will find the stiff 16K aluminised carbon faces punishing on mishits and demanding on the arm over the course of a long session.
About This Racket
Carbon face — stiff construction with direct power transfer. Crisp feel on contact that rewards clean striking technique with responsive ball speed. A reliable, high-performance surface for advanced players.
EVA core — a medium-density rubber that balances feel with energy return. Firmer than EVA Soft, giving a more direct response on hard contact and better power transfer on aggressive shots. Predictable and consistent rally to rally — a reliable all-round core.
Diamond shape with high balance. The head-heavy weight distribution increases leverage through the swing arc, translating directly into pace on smashes and aggressive volleys. The sweet spot sits high on the face — effective when attacking, but demands cleaner contact than a round or teardrop would.
Experienced players with developed technique who favour aggressive, attacking play. Suited to competitive club players who dominate from the net and want maximum pace on smashes and volleys. Demands clean contact — rewards it with explosive performance.
