The Siux Electra ST4 Pro Stupa 2025 is the latest evolution of Stupa’s signature series, designed for players who demand a racket capable of delivering explosive performance without sacrificing comfort or control. Built around a high-balance teardrop profile, the ST4 Pro offers a powerful, attacking feel while maintaining impressive manoeuvrability, ideal for players who love taking charge at the net but still need reliability in defence.
The faces are constructed with 15K Carbon, giving the racket a crisp, responsive touch that produces clean ball exit and excellent precision on volleys, bandejas, and attacking drives. Paired with a 100% carbon tubular frame, the structure feels incredibly stable through impact, helping you dominate exchanges with confidence. The core features a medium–hard EVA, tuned to deliver controlled power while still offering enough cushioning to keep the racket comfortable during longer rallies.
Siux has also refined the sweet spot and weight distribution, giving the ST4 Pro a more balanced feel when defending or transitioning to the net. Even when stretched deep in the court, the racket provides easy lift and stability, allowing you to stay in the point without needing excessive effort. A new surface texture enhances grip on the ball, giving you extra bite for spin and precision on cut shots.
With its premium aesthetics, smooth feel, and performance-driven design, the Electra ST4 Pro Stupa 2025 is built for players who want a complete racket, strong in attack, solid in defence, and fast in tight exchanges. Whether you’re an improving intermediate or an advanced competitor, this model offers the perfect blend of responsiveness, stability, and high-end playability.
If you want a racket that mirrors Stupa’s fast, aggressive style while remaining accessible and enjoyable for everyday players, the Electra ST4 Pro is one of Siux’s standout releases for 2025.
