Lok Carbon Fdb vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Carbon FDB Gen 2 continues Lok's simple pitch: serious hitting, sensible invoice. The EVA core produces power 85 with a direct, unfiltered strike, and value 78 undercuts every big-brand equivalent. The terms are unsoftened: control 71 is workable but demands a plan, comfort 65 and tolerance 64 assume conditioning, and maneuverability 67 wants anticipation at the net. Face documentation is incomplete, so verify the layup in hand. For improving attackers who buy on output rather than badge, the FDB Gen 2 is exactly the kind of rational purchase Lok has built its reputation on.”

“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.”
