Design updates and first impressions of the Siux Electra ST4 Pro
The Siux Electra ST4 Pro, signature racket of Franco Stupaczuk, arrives in its fourth edition with a refreshed look and subtle but meaningful design changes. The reviewer immediately notes the improved finish and striking aesthetics, describing the new colorway as reminiscent of bronze or gold—elegant without being overly flashy. Compared to previous Siux models like the Phenix, the Electra ST4 Pro stands out for its more refined details and a slightly baroque style that remains tasteful.
However, the reviewer is critical of the factory grip, calling it uncomfortable and poorly executed. This is a recurring issue with Siux, and the channel strongly recommends replacing the grip or adding extra overgrip layers for better comfort and control.
Technical specifications and construction details
The Siux Electra ST4 Pro is positioned as a hybrid racket, blending power and control. The channel highlights several key technical features:
- Face material: 15K carbon fiber
- Core: EVA hard (though the reviewer notes it feels more medium than truly hard)
- Balance: 26 cm (lower than the previous ST3, which was closer to 27 cm)
- Weight range: 355–375g (actual playing weight is typically 12g less than stated, due to packaging and accessories)
- Finish: Sandblasted surface for enhanced spin
- New detachable wrist strap system for easier cleaning and replacement
The racket’s core and heart structure have been reinforced, aiming for greater stability and power. The drilling pattern has also changed, with a non-perforated central zone that shifts the sweet spot lower, reminiscent of the earlier ST2 Pro model.
On-court performance and playability
Once in play, the Electra ST4 Pro reveals a slightly different character from its predecessor. The lowered balance (just above 26 cm) makes the racket more manageable and controlled, appealing to players who prefer a less head-heavy feel. The reviewer finds the racket especially suitable for those who strike the ball in the central area rather than the tip, as the sweet spot is now lower and more centered.
The impact is described as dry and crisp but not excessively rigid, with a response that is progressive rather than immediately explosive. The sandblasted face delivers reliable spin, and the racket maintains a solid sweet spot, though it is less generous at the tip compared to the ST3. The reviewer notes that the racket feels lighter than its stated weight, making it easy to maneuver but perhaps lacking in head mass for those who like to feel the racket’s tip during play.
For intermediate to advanced players—especially those playing on the right side—the racket offers a balanced mix of control and power. However, beginners or those seeking a very forgiving racket may find it less suitable due to the more focused sweet spot and the need for precise technique.
Comparison with other Siux models and competitors
The channel draws several comparisons to both previous Electra models and other Siux rackets like the Phenix. While the Phenix is described as having a longer lever and more pronounced head weight, the Electra ST4 Pro is more compact and easier to swing, though with less “presence” in the tip. The reviewer also compares it to the Babolat Counter Viper, noting that the Counter Viper feels heavier in the head and more communicative, while the Electra ST4 Pro is distinctly more maneuverable and has a drier touch.
Players who prefer a racket with a high balance and a strong head presence might lean towards the Counter Viper or earlier Electra versions. Those seeking a lighter, faster swing with good spin and a progressive response will appreciate the ST4 Pro’s updates.
Detailed feedback on shots: volleys, smashes, and spin
In volleys, the Electra ST4 Pro impresses with its solidity and full ball output, even at effective weights around 360g. The reviewer highlights the racket’s ability to generate both power and spin, with the sandblasted finish maintaining its texture even after extended use. The sweet spot is large enough for consistent performance, but players are encouraged to strike closer to the center for best results.
On smashes, the racket delivers decent power but is not a pure “cannon.” The lack of mass in the head means it requires good technique and a fast arm to maximize results, especially for flat and kick smashes. The reviewer notes that the racket activates slightly later, offering a “full” rather than “easy” ball output. For spin shots, the sandblasted surface and drilling pattern contribute to effective topspin and slice, with the finish holding up well over time.
For Vibora and Bandeca shots, the reviewer finds the racket very maneuverable but sometimes too light in the head, making timing slightly more challenging. However, the overall composition and materials ensure solid performance without needing excessive weight.
Comfort, grip, and user experience
Comfort is generally good, thanks to the racket’s manageable weight and balanced feel. However, the grip remains a major point of criticism. The reviewer finds the stock grip slippery and oddly shaped, with a small butt cap and a bulky central section that feels unnatural in hand. For a racket in this price range, the expectation is a higher-quality grip out of the box. The channel strongly advises replacing the grip or adding extra overgrip layers to improve handling and confidence during play.
The new detachable wrist strap is a welcome upgrade, making it easier to clean or replace, and adding to the overall practicality of the racket.

Final thoughts on the Siux Electra ST4 Pro’s place in the hybrid racket market
The Siux Electra ST4 Pro continues to be a standout option in the hybrid padel racket segment, offering a compelling mix of power, control, and spin. Its updated design and technical tweaks make it especially appealing to versatile players who value maneuverability and a progressive response.
