Quick Answer: The Siux ST5 Electra Pro 2026 ($389.99 on siuxusa.com) is Siux’s actual pro-player racket — the brand’s own US store names it the choice of world top-10 Franco Stupaczuk, the same player this site’s existing Siux roundup already credits as the brand’s sponsored pro. That roundup’s “best overall” pick, the Diablo Pro, is a completely different racket at almost the same price. Below the ST5 Electra Pro sits the high-balance Electra Elite ($299.95) and the budget Electra Go 4 ($119.99) — three tiers of a Siux lineup this site hadn’t reviewed until now.
This site’s best Siux padel racket guide has named Franco Stupaczuk as Siux’s sponsored World Padel Tour player since that guide published — but the racket it ranks “best overall,” the Diablo Pro, isn’t the one Siux’s own store ties to him. That’s the Electra line, reviewed here for the first time.
By the numbers
- Siux’s own US store describes the ST5 Electra Pro 2026 ($389.99) as “the racket of choice for world top 10” Franco Stupaczuk (siuxusa.com, October 2026) — not the Diablo Pro, which this site’s Siux roundup ranks “best overall” at an almost identical $389.95.
- The three Electra tiers span $119.99 to $389.99 on siuxusa.com, with carbon face construction scaling from a 50/50 carbon-fiberglass blend with a 3K Alumesh face (Electra Go 4) up to 3K solid carbon (Electra Elite) and 12K carbon (ST5 Electra Pro) — all three still looser than the Diablo Pro’s 24K TeXtreme face covered in this site’s best carbon fiber padel racket guide.
- Every Electra racket still fits the same International Padel Federation cap of 45.5 cm long, 26 cm wide, and 38 mm thick that governs every other racket on this site, per FIP’s published equipment rules.

1. Siux ST5 Electra Pro 2026 — Stupaczuk’s Racket
Siux ST5 Electra Pro 2026 (Shadow Red)
- Siux's own US store calls this "the racket of choice for world top 10" Franco Stupaczuk — the same player credited as Siux's sponsored pro in this site's Diablo-focused Siux roundup.
- 12K carbon face over an EVA core, built for what Siux describes as "dynamic, all-around performance" across both attack and defense.
- 355-375 g, teardrop (hybrid) shape, medium balance, 38 mm beam — nearly identical dimensions to the Diablo Pro, but a looser carbon weave.
- $389.99, four cents above the Diablo Pro's $389.95 — a near-identical price for a genuinely different racket.

The naming overlap is the trap here: this site’s Siux roundup already ranks a racket called the “Diablo Pro” as best overall, and the ST5 Electra Pro sits one letter-grade away in name and four cents away in price. But the two frames aren’t related — the Diablo Pro runs a 24K TeXtreme face, while the ST5 Electra Pro uses 12K carbon, a meaningfully softer, more flex-forward construction. If you’ve seen Stupaczuk’s racket mentioned anywhere on this site before, this is the actual frame, not the Diablo.
2. Siux Electra Elite 2026 — Best for Power Without the Flagship Price
Siux Electra Elite 2026
- High balance shifts the sweet spot toward the top of the frame, built for players who want to finish points at the net rather than rally from the back.
- 3K carbon face over an EVA Mid Touch core — a looser weave than the ST5 Electra Pro's 12K, trading some stiffness for feel.
- 360-375 g, 38 mm beam, teardrop shape — fractionally heavier than the ST5 Electra Pro.
- $90 cheaper than the ST5 Electra Pro, the clearest value gap in the lineup.
The Electra Elite is the racket for a player who’s decided they’re an attacker but isn’t ready to pay flagship price. High balance and a teardrop shape put the sweet spot exactly where a smash makes contact, and dropping to a 3K face only costs you some of the ST5 Electra Pro’s stiffness — not the shape or balance that actually define playstyle. For how that high-balance, attack-first profile compares across other brands, see our best padel racket for power guide.
3. Siux Electra Go 4 — Best Budget Electra
Siux Electra Go 4
- Siux markets this at intermediate players wanting "a more offensive tool without sacrificing control" — not true beginners.
- 50/50 carbon-fiberglass frame with a 3K Alumesh face, a different construction than the solid-carbon faces on the two Electra models above.
- Medium-hard EVA core for shot reactivity, with a glossy sandy finish Siux says boosts spin on vipers and trays.
- $10 more than this site's previously-reviewed Beat Hybrid Air ($109.99), which Siux positions as the true first-racket pick instead.
Don’t mistake the Electra Go 4 for a starter racket just because it’s the cheapest Electra. Siux’s own marketing language pitches it at players already past the absolute-beginner stage who want more offense than a round, forgiving frame provides. If you genuinely are picking up a racket for the first time, this site’s Siux roundup already covers the better fit — see our best Siux padel racket guide for the Beat Hybrid Air at $109.99.
Electra vs. Diablo: which Siux line should you buy?
Siux now sells two separate flagship-priced lineups through its US store, and nothing on either product page tells you that up front. The Diablo / Fenix / Trilogy / Astra family, covered in this site’s existing best Siux padel racket guide, is the broader five-racket range spanning beginner to all-court to control. The Electra family reviewed here is narrower — three tiers, all teardrop or hybrid shaped, built around the attack-and-defense profile Stupaczuk himself plays. If a World Padel Tour pro’s actual racket matters to your buying decision, it’s the ST5 Electra Pro, not the Diablo Pro. If you just want Siux’s best all-court frame regardless of pro-player tie-in, the Diablo Pro remains a legitimate, separate pick.
The bottom line
Buy the Siux ST5 Electra Pro 2026 ($389.99) if you want the racket Siux’s own store attaches to Franco Stupaczuk’s name, not the Diablo Pro this site previously ranked “best overall.” Step down to the Electra Elite ($299.95) for the same attack-first identity at $90 less, or the Electra Go 4 ($119.99) if you’re an improving intermediate player rather than a true beginner — for a first racket, this site’s best Siux padel racket guide still points to the cheaper Beat Hybrid Air instead.
