Lok Carb-on Flow Gen 2 vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Lok Carbon Flow Gen 2 is a round-shaped power racket that leans on its EVA core and even balance to deliver a punchy, predictable drive with decent forgiveness across the face. At 375g it sits on the heavier end, which rewards advanced players with good technique but will punish those lacking shoulder strength over longer matches. Lok remains a second-tier brand fighting for shelf space against established names, and at its price point it offers a serviceable but unremarkable option for attacking players who want raw pace without the premium price tag of top-market alternatives.”

“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.”
