“The Electra Pro in Fire Red is a lot of racket for the intermediate bracket it is aimed at: power 90 from the EVA core and Carbon 12K face means short lobs get finished properly, and the even balance keeps the frame from feeling like a sledgehammer between shots.”

Our verdict
The Electra Pro in Fire Red is a lot of racket for the intermediate bracket it is aimed at: power 90 from the EVA core and Carbon 12K face means short lobs get finished properly, and the even balance keeps the frame from feeling like a sledgehammer between shots. Control 78 is trustworthy on drives. The warnings are the usual ones at this output level: comfort 67 is firm for players still building technique, and tolerance 66 will punish the mishits that intermediates naturally produce. If you are an improving attacker with sound basics, it is a thrilling step up; if your contact is still streaky, demo first.

The series story
SIUX Electra
Stupa's hybrid line, from ST2 to ST5
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.
Which one should you buy?
Go straight to an Electra ST5 Pro edition if your budget allows. Both the Fire Red and the Shadow Stupa score 91 with us, and there is no meaningful performance difference between the two colourways. This is the most complete version of the Electra we have tested: it finishes points overhead with authority, stays composed under pressure in the back-court, and gives you enough feel at the net to play a proper bandeja when the rally demands placement over pace. If you find ST3 Stupa stock at clearance, a PRR 87 result is hard to argue with at a sharp enough discount. It remains a clean, capable racket and the gap to the ST5 barely registers on court when the price is right.
The Lite and Go editions are not lesser Electras so much as a different racket in character. Less swing weight, a softer overall response, better suited to players still developing consistency than to attacking players looking to load genuine finishing pace. They are honest options at the right price, but if you are after the full Electra experience, a Pro edition is the one to buy.
Genuine finishing power pitched at improving players: the even balance keeps your hands quick at the net, the face feels expensive and precise, and drives hold up under pressure. Be sure you'll use it — if your game is mostly rallying rather than attacking, this is too much frame, the hit is firm on a developing arm, and mishits get told off rather than forgiven.
