The adidas Metalbone CTRL 3.4 is a racquet built on the foundation of control, reaching the highest performance standards. The Weight & Balance System technology makes it a versatile model, adaptable to your needs in any situation. It is crafted from high-hardness Carbon Aluminized 16K fiber and low-density EVA Soft Performance rubber, which provides excellent ball output. Top-level play also demands power, which is why this model features the three new Metalbone technologies for 2025. The Power Extra Grip offers an extended handle that increases inertia during the swing, while the Low Poly polyhedral design in the frame and core, along with the Power Groove rail in the frame, enhances the racquet's structural rigidity. Additionally, the Spin Blade Decal texture guarantees precision when generating spin.
