“The Rx Series 2026 is adidas's recovery-and-rehabilitation frame in all but name: head-light, with an EVA Performance core and fibreglass face scoring comfort 76, tolerance 78 and maneuverability 78, with control 75 keeping placement dependable. Power 64 states the gentle brief. Weight documentation is incomplete. Value 76 is fair. The Rx name lands closer to honest than most: this is equipment for arms under management, players returning from injury, and anyone prescribing themselves kindness. Within that clinic, one of the more complete options at sensible money.”
“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.”
