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.
The REP® x PÉPIN dumbbells are offered in 32.5kg, 42.5kg, 52.5kg, or 62.5kg pairs. The 32.5kg pair meets the needs of most lifters but is still upgradeable to the heavier options in the future. The cradle also expands, so no matter the weight, you never need to buy a new cradle; simply unscrew the end pieces and screw them back into the correct, pre-drilled holes. These dumbbells feature high-end details, like nickel-plated handles with volcano-style knurling; functional side rails with comfortable, rounded outside edges; UHMW protective liners to prevent scratches from steel-on-steel contact; laser-etched weight markings (no cheap stickers!); and more. Pro-style heads look and feel like regular dumbbells, but the flat bottom still keeps the dumbbells from rolling on the ground. They’re further elevated with an aesthetic "REP® x PÉPIN" nameplate on the cradle and REP® mountain logo cutouts on the ends of the cradles. Make no compromises. A new bar for the best adjustable dumbbells has been set.
