Description
Part of REP’s Inventor Series, the REP x PÉPIN FAST Series Adjustable Dumbbell combines Canadian innovation with REP’s engineering expertise to deliver premium, compact and durable adjustable dumbbells.
Available in KG or LB versions, these dumbbells offer a maximum weight of 62.5kg (125lb) and a compact length of just 46.5cm, saving valuable gym space. Their all-steel construction features a black powder-coated finish, nickel-plated handles with volcano-style knurling, and an all-metal cradle with UHMW liners for added protection and durability. The slide-and-lock adjustment system allows for quick, secure weight changes, while the included microplates provide finer weight adjustments. The dumbbells also feature laser-etched weight markings, ergonomic side rails and flat-bottom heads to prevent rolling.
Weight Adjustment
- KG Version: 5kg increments, adjustable to 2.5kg increments using microplates. Includes 1.25kg microplates.
- LB Version: 10lb increments, adjustable to 5lb increments using microplates. Includes 2.5lb microplates.
Designed for long-term flexibility, the expandable cradle supports future weight upgrades without requiring new cradles. The 42.5kg (85lb) pair is recommended for most users, with expansion kits available for increased capacity. Upgrade kits must match the original dumbbell’s unit version, either KG or LB.
IMPORTANT NOTE:
● The REP x PÉPIN FAST Series Adjustable Dumbbells are designed exclusively for flat surfaces. Using them on angled trays, racks, or uneven surfaces may compromise their performance and stability, potentially leading to operational issues.
● As with all adjustable dumbbells with cradle storage, for successful pairing in cradle kindly ensure that the REP x PÉPIN FAST Series Adjustable Dumbbell is level with the cradle so the grooves and locking mechanism are able to align and fit properly.
● Before use, always ensure the microplate secure pin is fully engaged. The pin should make contact with the pin housing and the pin shaft should not be visible. Improperly securing the pin may cause the weight to dislodge and potentially result in injury or equipment damage.
