Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 81/100 for the Nox Quantum Cobalt 12K 2025 1. Its biggest edge is power (+4). The Nox Quantum Cobalt 12K 2025 1 answers back on comfort (+9).
“The Quantum Cobalt shares the diamond-shape, 12K carbon, HR3 Color EVA construction of the standard Quantum Carbon — same power-first performance case, different colourway for players who want the Lamperti/Osoro Quantum look without the primary finish. PRR score: 81/100.”
“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.”
