The Vibor A Vibor-A Black Mamba Radical 12K 3.0 answers back on comfort (+9). On price, the Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk is currently €66 cheaper.
“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.”
“Black Mamba is Vibor-A's flagship attacking line, and this Radical 12K 3.0 keeps the teardrop shape and medium-high balance with a 12K carbon face and EVA Pro core for genuinely strong smash power. PRR score: 83/100.”
