Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

The SIUX Electra is built around a specific kind of game. Franco "Stupa" Stupaczuk plays at full intensity at the net, finishes points overhead, and is never out of a rally through the glass. SIUX designed the Electra to match that: a hybrid shape that sits between a control-first round and a pure power diamond, loading up genuine finishing pace while keeping a face soft enough to play touch padel. That balance is harder to achieve than most brands admit, and the Electra has been one of the few rackets in our database to genuinely hold both ends of it.

We have tracked the line across three generations. The 2023 ST2 Pro scored 85 with us and set the Electra template: fast through the air, composed under pressure, with a face that let you redirect a vibora or place a clean bandeja without needing to think twice. The 2024 ST3 arrived with a stiffer hitting surface and better stability when opponents loaded pace at you; the ST3 Stupa scored 87, with Lite editions widening the family to lighter swing weights for improvers. The current ST5 Pro editions, Fire Red and Shadow Stupa, both score 91, the highest result SIUX has achieved in our database.

Each generation follows the same structure: a Stupa Pro edition at the top, designed for attacking players who want to smash overhead and still play a composed bajada off the back wall, with Lite and Go trims below for players building toward that kind of game. The ST generation number is the real thread through the range, and what the Electra has consistently rewarded is a particular construction of points: build through the glass, close at the net, finish overhead.
