REP x PÉPIN Fast Series Adjustable Dumbbell Set

The REP® x PÉPIN FAST Series Adjustable Dumbbell is part of REP’s Inventor Series, a collection designed in collaboration with standout creators like Canada-based Pépin. These adjustable dumbbells are compact, heavy-duty, and built entirely from steel—with weight options up to 125lbs in a space-saving 18.3" footprint. Weight adjusts quickly in 10lb increments using a magnetic pop-pin, or more finely with included 2.5lb micro-plates, all without needing to change cradles as you upgrade. Key details include nickel-plated handles with volcano knurling, pro-style heads, protective UHMW liners, and laser-etched markings for long-term durability. Designed for flat use only, this is one of the most premium and practical adjustable dumbbell systems available—no compromises.

• HEAVY AND COMPACT: These are heavier and more compact than most adjustable dumbbells on the market. An adjustable dumbbell that can go up to 125lbs and is only 18.3" in length is pretty much unheard of.
• EXTREME DURABILITY: Both the dumbbells and cradles are made with full metal construction and have been extensively drop-tested from every angle.
• SPACE SAVING: Adjustable dumbbells take up a very small footprint in your gym when compared with a 10-85lb, 10-105lb, or especially a 10-125lbs dumbbell set.
• FAST WEIGHT CHANGES: Quickly and easily change weight in 10lb increments by popping and sliding the magnetic pop-pins into place. Add 2.5lb micro-adjustment plates to increase weight by 2.5lb or 5lb increments up to 125lbs.
• EXPANDABLE: The basic pair of adjustable dumbbells spans 10 to 85lbs, with the option to add more plates later up to 125lbs. The cradles expand with the size of your dumbbells, too.
• NICKEL-PLATED HANDLES: Nickel-plated handles are 34mm in diameter and feature a volcano-style knurling pattern that provides plenty of grip without being overly aggressive.
