Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 64/100 for the Vibor A Belcher Classic Fiber. Its biggest edge is power (+32). The Vibor A Belcher Classic Fiber answers back on sweet spot (+8). On price, the Vibor A Belcher Classic Fiber is currently €104 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.”
“The Belcher Classic Fiber is Vibor-A's accessible round option, built around a fibreglass face for a forgiving, comfortable strike rather than raw output. Unisex positioning and genuinely low pricing make it an easy, low-risk racket for a beginner or improving player.”
