The Metalbone Carbon 3.4 introduces two cutting-edge adidas technologies to the Metalbone range for the 2025 collection. These include the Power Extra Grip, an extended racquet handle that enhances inertia during shots, and the Low Poly polyhedral design in the core and frame, which increases rigidity—both essential for offensive play. In addition to these innovations, the Octagonal Structure, a tubular carbon frame, reduces torsion and improves shot accuracy. The combination of EVA Soft Performance rubber and Carbon 6K fibre provides a perfect balance, while the Spin Blade Decal relief ensures precise spin effects. Octagonal Structure The strength of the Metalbone range comes from this tubular carbon structure, which ensures stability and high resistance to torsion. Located in the frame, it guarantees maximum rigidity and offers great precision in all types of shots—the perfect balance every top-level racqet needs. Low poly An innovative design in key areas of the racquet. This technology gives a polyhedral shape to the frame and core, which enables better force distribution upon impact. As a result, the structural rigidity of the racquet increases substantially, offering improved performance on the most powerful shots. Extra Power Grip This innovative longer grip significantly increases the racquet's inertia during shots, especially in offensive strokes. The longer-than-usual distance between the bottom of the handle and the top of the head allows for greater swing speed and more powerful impacts.
