Siux Electra ST4 Pro Stupa vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The ST4 Pro Stupa is Stupaczuk's 2025 frame with the confirmed vitals of a modern attacker: even balance, 365 g, and a scorecard that reads first-strike padel. Power 88 converts pressure into finished points, control 76 keeps heavy drives inside the lines, and comfort 67 with tolerance 66 tells you the strike is firm and honest about mishits. Beyond weight and balance, the full specification is unconfirmed, so demo before committing. Value 78 reflects the run-out pricing on last season's signature line: for aggressive all-courters, it is a lot of racket for the money.”

“Franco Stupaczuk's Shadow Red ST5 is built to attack: power 90 with control 78 is a proper first-strike profile, and the confirmed even balance at 365 g explains why it feels quicker between shots than its hitting power implies. Blocks and counters stay manageable, then the same frame turns a short lob into a finished point. The firm side is unavoidable: comfort 67 and tolerance 66 mean mishits are felt and punished. Beyond balance and weight, full spec for this colourway is unconfirmed, so try before you buy. For aggressive all-court players it is a convincing signature frame.”
