REP® x PÉPIN™ FAST Series™ Adjustable Dumbbell

Pre-Order
  • The REP® x PÉPIN™ FAST Series™ Adjustable Dumbbell represents a precision collaboration between REP and Canada-based PÉPIN, engineered through REP's Inventor Series to deliver uncompromising performance in a compact footprint. Built from CNC-cut steel plates with durable black powder coat, these dumbbells combine dense all-steel construction with fast, intuitive adjustments and premium fit and finish.

    Both dumbbells and cradles are fully metal, reinforced with UHMW liners to prevent steel-on-steel contact, and extensively drop-tested for confident racking and hard training. Available in two weight standards—LB version scaling 10 lbs to 125 lbs at just 18.3" long, and KG version ranging 40 kg to 60 kg in a compact 46.5 cm length—each features fast magnetic pop-pin adjustments, micro-plates for precise increments, expandable steel cradles, nickel-plated volcano-knurled handles, and laser-etched weight markings. Both versions are fully upgradeable over time, offering one system across two standards with no compromises on precision-built strength.
