Electric Speed. Explosive Power. Play Like Stupa.

The Siux Electra ST4 Stupa Pro 2025 is the definitive evolution of Franco Stupaczuk’s famous "Electra" line. Designed for the dynamic, all-court player, this racket captures the essence of Stupa’s game: lightning-fast reflexes at the net and explosive power when smashing.

If you are an advanced player looking for a racket that feels agile in defence but transforms into a hammer on the attack, the ST4 is your perfect match.

Designed for Versatile Dominance Built with a Hybrid Teardrop shape and a Medium-High balance, the ST4 offers the sweet spot of a round racket with the leverage of a diamond. It allows you to defend difficult balls with ease and then switch immediately to offense, generating effortless racket head speed for vipers and smashes.

Premium Materials & Technologies (2025 Upgrades)

• 15K Carbon Face: A high-performance carbon weave that strikes the perfect balance—harder than 12K for more power, but flexible enough to retain feeling. It provides a crisp, electric pop on impact.
• Black EVA High Recovery Core: A high-density rubber that recovers instantly after impact, delivering maximum energy transfer into the ball for faster shots.
• Sandy Rough Finish: A gritty, sandpaper-like texture applied across the face to bite the ball, significantly increasing spin on bandejas and viboras.
• Reinforced Bridge: The structural design minimizes twisting on off-centre hits, giving you stability even when blocking heavy shots.
• Dual Pro Grip & Dampeners: Engineered to reduce vibrations travelling to the arm, allowing you to play longer matches with less fatigue.

Optimised for South African Conditions The 15K Carbon Face is exceptionally well-suited to the South African climate.

• High Altitude Power (JHB/Pretoria): The crispness of the 15K carbon prevents the ball from "floating" too much in the thin air, giving you the control needed to keep smashes fast but accurate.
• Coastal Performance: The hybrid aerodynamics cut through the heavier coastal air in Durban and Cape Town, helping you maintain swing speed even in breezy conditions.
