Siux Electra Flow 4 Padel Racket

Start with the name. Shops call it the Electra Flow 4, the Electra 4 Flow and the Electra ST4 Flow, and listings carry both 2025 and 2026. The 4 is Siux's generation number for the Stupaczuk Electra line, which is why the 2024 racket is the ST3 Stupa Pro (with a softer ST3 Go alongside), the 2025 racket the ST4 and the 2026 racket the Electra Pro 2026.

On specification, Padel Nuestro describes a hybrid design with a 12K carbon face, a 3K carbon frame and a hard EVA core. One retailer gives 365 g and an even balance; Totalpadel calls it round at 355 to 365 g for advanced players; a retailer blurb calls it accessible, control-oriented and aimed at intermediates who value manoeuvrability and arm comfort. Some markets list the core as EVA, others as soft or hard.

Where we have to pick, we use ranges and say which source we followed. We do not quote a balance in millimetres because none of the sources we could reach publishes one.

The nearest tested relatives are the Electra Pro (reviewed in both its Fire Red and Shadow Red colours), which Padelful scores 9.1 for control with a 15K face, and the Electra Elite 4 from 2025, which Padelful scores 8.4 for control, 8.3 for power and 9.1 for manoeuvrability with a sweet spot of 7.3. Both are teardrops with a medium-hard feel.

The Flow is not either of those, and we have no basis for assuming it plays like them. What we can say is that the family character is a firm, precise teardrop-ish racket, and that a hybrid with a 12K face sits in that neighbourhood. Treat any claim about how it plays, including ours, as an expectation rather than a result.

Padel Nuestro describes Siux's tiers as Pro, Elite and Go, from the most demanding to the most forgiving, and does not say where the Flow falls, though listings that aim it at intermediates suggest the gentler end. For the full Electra, the Electra Pro is the verified choice. For a softer way into Siux, the Diablo Pro has an even set of scores and a medium feel, and our Siux padel rackets page explains the naming across the range.

Anyone who needs to know exactly how a racket plays before paying. With no published test and a spread of conflicting listings, you are buying on faith. If you want certainty, the advanced padel rackets page lists rackets with measured scores, and the best padel racket for intermediate players page does the same one level down.

Whatever the core turns out to be, a fresh grip helps. A cushioned replacement or a tacky overgrip such as the Head Pro overgrip is the usual choice, and our padel grips page explains the difference. Fit frame tape from the racket protector range before the first match.

Fresh balls make any carbon racket feel livelier, so a tube of Bullpadel Next balls is a sensible companion, and the padel balls page explains how quickly pressure fades. The padel bags page has bags with a thermal pocket, and court shoes are on our padel shoes page.

For the wider picture, the full padel racket range is on one page, and our guide to choosing a padel racket explains how shape and balance change the feel.
