Lok Carb-on Hype FDB vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Lok Carb-on Hype FDB 2025 is a mid-tier offensive racket from a relatively obscure Spanish brand that attempts to compete in the carbon-heavy performance segment without fully delivering on that promise. The diamond-leaning shape offers decent smash generation but the frame stiffness can transmit unwanted vibration over extended play, making it less forgiving on the arm than rivals at a similar price point. Intermediate attacking players seeking a budget entry into carbon construction may find it serviceable, but those with options in the same bracket would be better served by more established names.”

“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.”
