Siux Electra Stupa Pro ST4

Franco Stupaczuk's official racket for 2025. This high-performance model is designed for players who dominate the court and seek a combination of power, precision, and maximum spin. With its hybrid shape and medium balance, this racket offers versatile and powerful performance in expert hands. The faces are made of 15K carbon, an ultra-resistant material that allows for explosive response on every shot. The 3K carbon frame provides structural lightness and rigidity, while its Hard EVA rubber offers a firm feel, ideal for generating speed and aggression without sacrificing control. The glossy, sanded finish maximizes spin on lobs, volleys, and smashes. It also includes the new Switch Strap system for interchangeable straps.
