The Metalbone 3.4 combines all the technological and structural features to excel at the highest level of performance. It is one of two 2025 adidas models for Ale Galán. Metalbone makes a bold statement this year with three new technologies for a complete attacking game: the extended Power Extra Grip handle, offering greater swing inertia; the Low Poly polyhedral design of the frame and core, which boosts power; and the Power Groove rail on the frame, increasing structural rigidity. This powerful trio of technologies is further enhanced by the Weight & Balance System, allowing you to adjust the balance and weight of the racket for greater power or improved control. Its Carbon Aluminised 16K fibre composition and EVA Soft Performance rubber ensure stiffness and excellent ball output. Lastly, the Spin Blade Decal takes spin to the next level.
