Akkeron Fenix A25 vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Fenix A25 is Akkeron borrowing Siux's bird for its own even-balanced attacker: an HR3 core under a 3K face scoring power 78 with fair terms (comfort 67, tolerance 66) and honest handling (69). Control 68 wants organised targets. Weight documentation is incomplete. Value 74 stays competitive. The HR3 core gives the strike the lively, springy quality that distinguishes Akkeron's better frames from the EVA mainstream. The usual challenger asterisk applies; the usual challenger answer, a genuinely interesting feel at pressure pricing, applies too. Demo-worthy for the open-minded improver.”

“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.”
