What padel racket does Franco Stupaczuk use in 2026? The No. 6 in the Premier Padel men's ranking plays with the Siux Electra ST5 Pro Shadow Red, a diamond-shaped racquet by Siux.
The Siux Electra ST5 Pro Shadow Red is a pure power racket: a diamond shape and medium-high balance concentrate the mass in the top of the head to maximize the smash. It shines on smashes, viboras and aggressive net play. Its weak point is that it demands refined technique and an experienced arm, as it forgives off-center hits less than a round racket. Recommended for advanced and competition-level attacking players.

The Siux Electra ST5 Pro Shadow Red is Franco Stupaczuk's official racket on the 2026 Premier Padel tour. The ST5 (SuperTouch 5) technology in its 12K carbon faces provides a solid structure and explosive ball output, while the EVA Premium core delivers a reactive, precise and consistent response.
With its signature dark burgundy look and teardrop shape with medium balance, this racket combines controlled power with precision, adapting perfectly to every situation in the match. A weapon built for the most demanding moments of the professional tour.
It is built for an offensive, advanced or competition-level player who owns the net position and finishes points with smashes and viboras. The medium-high balance shifts the weight toward the head, so it rewards players with strength, good timing and the technique to exploit that leverage. As a competition-grade racket, it is aimed at players who have already mastered the basic strokes and want to squeeze out maximum performance, just like Franco Stupaczuk on the Premier Padel tour.
