Description
Who this racket is for
Pros
- ✓The sandpaper-like finish grips the ball on cut shots — víboras and sliced bandejas come off the frame with a rotation your opponent feels on the bounce; the Shockout anti-vibration system paired with the EVA Soft core soaks up off-centre impacts, letting you play multiple matches in a weekend without your elbow paying the price; the medium balance in a teardrop shape gets to the net fast for volleys and still lets you correct the face when a ball is fed to your body at the net; the Antitorsion Bridge stiffens the bridge and stops the head twisting on bandejas struck near the top of the frame, where other teardrops tend to open up; wall exits are forgiving thanks to the soft rubber — rushed blocks are forgiving and lobs carry deep without needing to muscle the shot with your shoulder
Cons
- ✗The EVA Soft core takes some punch off the flat smash — coming from a harder core, you'll notice the ball doesn't fire off on its own and you need to put your arm into it; the sweet spot is solid for a teardrop shape, but contact well off-centre loses noticeably more response than you'd get from a round-shaped racket; the 375g upper end of the weight range makes itself felt in the third set if you're not fully fit by the closing stages; the 38mm frame and competition-level feel demand clean ball-striking — below intermediate-advanced level, it asks for more precision than it gives back

The Siux Electra ST2 Stupa Pro 2023 is designed for competition or pro-level players who prioritise performance and precision over comfort. Its teardrop shape shifts the sweet spot slightly upwards, striking a balance between control and power. The medium balance keeps a balanced behaviour between baseline shots and volleys. Its 355-375g weight range places it in the medium-weight group, the most common among amateur players.
Siux Electra ST2 Stupa Pro 2023 Review: The Teardrop That Softened Stupa's Touch
15K carbon on both faces, an EVA Soft core, a 38mm frame and a weight range of 355 to 375g. With those numbers, Siux built its 2023 signature racket for Franco Stupaczuk: a medium-balance teardrop padel racket designed to hold up over a full competition season without beating up your arm.
The on-court results back it up. Stupaczuk closed out 2023 inside the top six of the Premier Padel ranking, with seven titles that season and the Doha Major on his résumé. This padel racket isn't a marketing exercise with a signature slapped on top.
How Does the Electra ST2 Improve on the Siux Electra ST1?
The difference sits in the face material. The Siux Electra ST1 — the racket Stupaczuk used to win the Mendoza Premier and the French Open in 2022, plus finals runs in Amsterdam, Málaga and Brussels — had a drier, more direct feel.
The ST2's 15K carbon face noticeably softens that ball exit from your very first volley. You lose some of the previous generation's instant pop, but you gain dwell time: the ball stays on the strings a few milliseconds longer, which translates into better placement.
Underneath, the fully carbon tubular structure holds everything together. It's what stops a friendlier face from turning into a lifeless one.
Shockout, Antitorsion Bridge and Dual Pro Grip: What Each Technology Actually Does
Three systems, three distinct jobs, none of them just for show.
- **Shockout anti-vibration**: filters the vibration that travels up the handle on off-centre hits. Combined with the EVA Soft core, it's the reason you can play three matches back-to-back without your elbow complaining.
- **Antitorsion Bridge**: stiffens the bridge and cuts down head rotation on off-axis contact. On sliced bandejas near the top of the frame, the face doesn't twist open on its own.
- **Dual Pro Grip**: the handle's grip system, built with dual density so your hand doesn't slip on the wrist snap of a víbora.

From the Smash to the Wall Exit: How It Plays on Court
The medium-balance teardrop shape is a deliberate choice. The weight isn't pushed as far forward as on a diamond racket, so the head gets to the net quickly for volleys and still allows you to adjust the face when a ball is fed into your body.
On the smash, ball exit is honest without demanding a perfect swing: the EVA Soft core loads and releases well, and the kick serve gets enough height to push your opponents off the court. The flat smash has bite, but it won't send the ball off on its own — you need to commit your arm.
On víbora and bandeja, the sandy surface earns its keep. The sanded finish grips on cut shots, and the sliced ball comes off with rotation you can see in the bounce. This racket is built to play with spin, not to flatten out every shot for three sets straight.
On defence, wall exits feel comfortable: the soft rubber forgives a rushed block and lobs carry deep without needing extra shoulder drive. The weak spot shows up on contact far from the geometric centre, where response drops off more than it would on a round-shaped frame.
What Level Is the Siux Electra ST2 Stupa Pro Built For?
It's aimed at competition-level players with solid technique who want an all-round padel racket that balances power and control evenly, without leaning hard toward either extreme. It demands clean striking and a trained wrist to get the most from the sandy surface; below intermediate-advanced level, the 38mm frame asks for more precision than it gives back.
Who it suits:
- Backhand-side players who mix bandeja and víbora and need to defend their way out of trouble with a lob.
- Forehand players who smash with spin and placement rather than raw power.
- Players with a history of elbow or wrist issues who don't want to give up a tour-level racket.
As a pairing, it works best alongside a more aggressive partner running a harder rubber — the ST2 handles the point-construction side of things.
What This Siux Racket Won't Give You
It's not a pure power racket. If you're coming from a hard core expecting the ball to fire off without any input from you, the EVA Soft core will feel slow on the flat smash.
It's also not the most forgiving off-centre, and the 375g at the top of the weight range starts to show late in the match if you're not fully fit.
What to Expect Over a Full Season
A racket that delivers exactly what it promises: soft touch, bite on spin shots and joint protection, in exchange for giving up the sharp, explosive pop of a hard rubber. Players chasing a pure smash weapon should look toward a diamond shape with a stiffer core; players who want to play all four shots with the same racket will find a rare balance here for a competition-level signature model.
