Frequently Asked Questions

Why does the total plate weight not exactly match the set name (e.g. the 50kg set)?

The set name refers to the overall package, while the plates themselves make up slightly less than that figure — for example, the 50kg set contains 48kg of plates, with the remaining weight made up by the bars, connector, and nuts. This is standard across adjustable dumbbell and barbell sets in general.

Can this be used as both dumbbells and a barbell?

Yes, using the included connector rod and nuts, the two dumbbell bars can be joined together to form a barbell, or used separately as a pair of dumbbells.

What weight options are available?

20kg, 30kg, 40kg, and 50kg sets.

What's included in each set?

Each set includes dumbbell plates, two dumbbell bars, one connector rod, and four nuts. The exact plate breakdown varies by set — see the dimensions table above for details.

What are the bar lengths?

Bar length varies by set: approximately 40cm for the 20kg set, 47cm for the 30kg set, and 51cm for the 40kg and 50kg sets.
