Updated 6 October 2026. Choosing adjustable dumbbells for a Singapore home gym comes down to four practical questions: what weight range you need, how small the increments are, where the set will live, and whether the price includes one dumbbell or a pair.
This guide compares the adjustable dumbbells sold by Carbyne Fitness so you can choose equipment that suits your HDB, condo or other home workout space. Browse adjustable dumbbells and current prices.
Compare weight ranges and increments
All ranges below are per dumbbell. The maximum weight is not the weight of the pair combined.
| Model | Weight range per dumbbell | Adjustment increment | What to consider |
|---|---|---|---|
| CARBYNE 235 | 4–23.5kg | 1.5kg | Choose this if the upper weight limit covers your planned exercises. |
| CARBYNE 325 | 4–32.5kg | 1.5kg | More headroom with the same smaller increments. |
| CARBYNE 415 | 4–41.5kg | 1.5kg | The highest maximum weight in this three-model series. |
| 36KG Quick Adjustable Dumbbell | 3–36kg | 2.25kg | A lower starting weight with larger steps between settings. |
| 40KG Adjustable Dumbbell | 2.5–40kg | 2.5kg | Compare the larger increments with the weights you use today. |

Which adjustable dumbbell should you choose?
Choose the increment as well as the maximum weight
A smaller increment gives you more settings between your current weight and the next one. The CARBYNE 235, 325 and 415 use 1.5kg increments; the Quick Adjustable options use 2.25kg or 2.5kg increments. Compare those steps with the loads you use for presses, rows and smaller accessory exercises.
Allow room for your next stage of training
Choose a maximum weight that covers your current exercises and realistic future needs. A set that is sufficient for shoulder exercises may not be enough for your heavier rows or lower-body exercises. You do not need to buy the heaviest option automatically: the useful range for your own training matters more.
Single dumbbell, pair and rack: compare the complete price
The CARBYNE 235 / 325 / 415 product page lets you choose one dumbbell or two, plus a rack option. A collection's starting price is not necessarily the price of the pair pictured. Select the exact weight, unit count and rack option before comparing totals.
As checked on 6 October 2026, a pair of CARBYNE 23.5kg dumbbells without a rack is S$638. The CARBYNE Stepper Adjustable Bench is S$229, giving an example dumbbell-and-bench setup of S$867 before any additional flooring or storage. Prices and availability can change; the selected product variants show the current total.

Plan the workout space, not just the storage corner
Measure where the dumbbells and cradles will sit, then allow clearance to pick them up, adjust them and complete your exercises. If you use a bench, account for its operating dimensions and room around it. A compact storage footprint does not mean every exercise fits in the same small area.
A rack can make storage and access more convenient, but it adds cost and floor space. Check that the rack matches your dumbbell model: Carbyne Fitness sells different racks for the CARBYNE series and the Quick Adjustable series.
Care, flooring and local support
Keep the equipment dry after use and follow the instructions for your model. Return adjustable dumbbells to their cradles carefully and avoid dropping them. Suitable gym flooring helps protect the surface, but it does not eliminate impact or vibration.
Check the product's warranty terms and ask about replacement parts before buying. For the CARBYNE 235 / 325 / 415 series, the published warranty is one year; the product page explains coverage and exclusions.
