Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk wins by 16 points
Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 75/100 for the Tecnifibre Curva Soft. Its biggest edge is power (+19). The Tecnifibre Curva Soft answers back on sweet spot (+6). On price, the Tecnifibre Curva Soft is currently €48 cheaper.
“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.”
“The Curva Soft 2025 is last season's pressing of Tecnifibre's gentle entry frame: a 360 g foam-core build with a carbon-fibreglass face scoring the same even 71/71 split and civil terms (72/72) as the current Curve Soft. Run-out pricing lifts value to 74, ahead of its successor. The twin-listing rule applies across seasons as within them: identical character, different invoice, buy the cheaper. For improvers who want the brand's clean, kind entry offer, last year's Curva at a discount is the arithmetically correct choice. Check remaining stock condition.”
