This exclusive edition of the Siux Electra ST4, developed in collaboration with Franco Stupaczuk, is designed for advanced and tournament-level players who demand the very best from their equipment. With a focus on power, precision, and spin, this racket is built for the technically skilled all-round player.

The Siux Electra ST4 Rulo features a medium balance and a hybrid head shape, offering great versatility between control and power. Compared to the Siux Electra ST4 Stupa Pro, the Rulo version is slightly stiffer, delivering a firmer feel and a more direct response in your shots, reminiscent of the ST3 version.

Its 15K carbon surface ensures explosive energy with every hit, while the 3K carbon frame combines low weight with high rigidity. The firm EVA Hard core provides quick rebound and aggressive power without compromising ball feel. Finally, the racket’s glossy finish and sandpaper-like texture enhance grip on the ball – perfect for spin-heavy shots such as viboras and bandejas.
