Akkeron Black Pegasus Pro vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Black Pegasus Pro is Akkeron's swing-weight attacker: an HR3 core under a 12K face in an even-balanced 375 g build, producing power 82 with a lively, springy response the foam core makes distinctive. Control 70 is workable, comfort 66 and tolerance 65 hold the firm line, and maneuverability 68 wants anticipation. Value 74 stays competitive. As with all Akkeron frames, the challenger caveats ride along: thin network, uncertain resale. The frame itself argues confidently: proper materials, real pace, honest money. Improving attackers open to the unknown badge get a genuinely lively weapon.”

“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.”
