Nox At10 Genius Ultralight By Agustin Tapia vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The AT10 Genius Ultralight is Tapia's name on 325 g, the lightest frame we score: maneuverability 80, comfort 76 and tolerance 77 define an experience where the racket simply never arrives late or argues. Power 68 and control 70 are the transparent physics of the weight. Value 80 is fair for the speciality. The audience is precise: juniors stepping up, players managing serious arm trouble, and net specialists who count every gram. For them, nothing else serves quite like this; for standard arms, it is a lovely answer to a question they have not asked.”

“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.”
