Great dumbbells

Very glad to have come across these dumbbells as the other dumbbells readily available in Singapore are not exactly what I'm looking for. Carbyne's checked all the boxes for me. The weight plates are wide, but that allows it to stack up and remain as short as it can economically be without resorting to heavier, costlier materials just to make it compact.

I got the silver one. The sounds it may make are not something that's a bother at all, and I preferred it to the black one for the silver one is full metal. In fact, I use the presence (or rather, the absence) of sound it makes as an additional audio cue to how unstable (or stable) my dumbbell movements are. Under normal usage, it wouldn't make a sound other than the usual sounds when you adjust the weight, remove, or put the dumbbells back to the holder.

The rack is quite well-made too, though some parts have some sharp edges that one ought to be careful of and perhaps smoothing it out, but those edges won't come into contact when you're using the dumbbells.

If you're not able to lift the entire 41kg dumbbell by yourself and need to move it a few plates at one time, please be mindful of the arrangement of the plates. Put them back how you took them out when relocating the dumbbells. The weight plates are also lightly oiled for protection against oxidation, so don't wipe them out entirely either.

The less-used weight plates will likely have dust settle over them over time if you're not at the point of using them regularly, so do consider getting some kind of a dust cover for them.

My previous pair of dumbbells are just the regular dumbbells and they simply take far too long to adjust precisely. I'm not going to drop them either, so I expect to be able to use these monsters for a very long time to come.

Excellent service

Ordered a pair of CARBYNE 16KG Quick Adjustable Kettlebells on 27 Sep 25 at about 10pm from Shopee. Received on 28 Sep 25 11am morning! If that isn't service I don't know what is. Dan whom delivered was polite and called as I wasn't home. Items well packed with styrofoam and bubble wrap. Having used only dumb/bar bells in the past can't wait to get stuck into these 👍. Thank you Dan and Carbyne Fitness

Stable, compact & convenient!

Stable, compact, convenient to adjust weight. Good grip for the average palm size. Possible to do L-sits with the weights on their holders. I prefer black over the metallic version as it creates less clanking sound when I hit against the other plates left on the holders. Probably possible to tie the plates to yourself with a strap for pull ups or dips. Very responsive seller

Solid!

Bought adjustable dumbbells recently from them. Impressed with how sturdy they are. The build feels solid, weight changes are quick and smooth, and they save a lot of space in my HDB compared to traditional dumbbells. Perfect for home and what I need.

Very happy !

Our first set of adjustable dumbbells and we are very happy we decided to purchase from Carbyne Fitness.

The built feels very well made, and the turning mechanism for choosing the desired weight is very well done. The simple and minimal black design is aesthetically pleasing, and the compact form makes it ideal for home gyms and small spaces.

Also, we were very surprised by how fast the delivery was. Overall, very happy with the purchase and we would like to thank Nad as well for the great customer service provided.

Great experience!

Great buying experience for the Carbyne Adjustable dumbells. Contacted almost immediately after online purchase and delivery was fast! Carbyne even checked in a few days later to see how the experience of using the dumbells were. Can feel the warmth and friendliness of the Carbyne team!
