Siux Electra Stupa Pro ST4 (2025)

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.
