SIUX ELECTRA ST4 RULO

SIUX ELECTRA ST4 RULO 2025

Explosive spin. Limited-edition performance.

The Siux Electra ST4 Rulo 2025 is a limited-edition version of Franco Stupaczuk’s iconic Electra series, designed for advanced and professional players who want a perfect mix of power, control, and spin-oriented aggression. Built for dynamic all-court play, it delivers explosive acceleration while maintaining excellent maneuverability and precision.

Its hybrid / teardrop shape and medium-high balance create a versatile racket that transitions naturally between defense and attack. The combination of a 15K carbon surface and EVA Hard core provides a crisp, medium-hard feel with excellent ball output and strong shot precision. Players often describe it as more explosive and firmer than softer control-oriented models, while still remaining highly manageable.

The racket features a rough sandy finish (“Rulo” texture) that improves grip on the ball and enhances spin generation for viboras, bandejas, and slice shots. Its 3K carbon frame reinforces stability and durability during high-intensity rallies.

Independent reviews and community feedback frequently describe the Electra ST4 as one of the most balanced “all-round attacking” rackets available, appreciated for its maneuverability, firm feel, and strong offensive capabilities. Many players also highlight its excellent sweet spot and versatility compared to harder pure-power rackets.

Some community discussions, however, mention occasional quality-control inconsistencies between individual Siux rackets due to handmade manufacturing variations, especially regarding weight and finish.
