Talk to a equipment specialistIf you train at home and want a full dumbbell rack in one footprint, the Cortex Revolock V2 dials each dumbbell from 2kg to 40kg across 16 increments, so a single pair covers your whole session. The fast RevoLock system with its anti-jam curved guide changes weight in seconds without loose collars.
It suits a lifter who also wants a barbell option, converting to a 2.5kg to 41kg barbell for presses, rows and curls, all stored on the included Revolock V2 stand. Knurled steel handles and heavy-duty steel plates give it the solid feel of a fixed set.
The RevoLock system is the detail I'd flag: the anti-jam curved guide means dialling from 2kg to 40kg is one clean twist, not the fiddly plate-swap most adjustables force on you.
It isn't built for overhead work, so treat it as a press and row set. The standout is versatility: 32 combinations plus barbell mode, all on one included stand.

One set covers your whole session. Dial dumbbells from 2kg to 40kg in 16 increments, then reconfigure as a barbell from 2.5kg to 41kg for the heavier compound lifts.
The RevoLock system lets you change load in seconds, so you keep moving between sets instead of stopping to swap plates.
What this means for you: One compact set replaces a full rack of fixed dumbbells and a loaded barbell, which is why it works so well for home training in a spare room or garage.
The curved guide inside the RevoLock mechanism steers the plates into place cleanly, so the weight selection engages smoothly rather than snagging mid-adjustment.
Underneath, heavy-duty steel and a reinforced interlocking centre rod carry the load through heavy sets.
What this means for you: The knurled steel handles hold in sweaty hands, which matters most on your last few reps of a heavy set.
The dedicated stand comes in the box, so you have a home for the handles and plates from day one rather than leaving them on the floor.
It keeps everything at working height and holds the unused plates in a defined footprint.
What this means for you: Adjustable sets live or die on their storage. A tidy stand keeps the set usable in a shared space instead of becoming clutter.
This ships as a complete set: dumbbell handles, barbell tubes, weight plates, the stand, plus manual and hardware. You assemble the stand and load the trays on arrival.
It ships across 3 cartons with a combined gross weight of 108 kg.
What this means for you: Setup is a one-person job with a spanner (fixings included), usually 45 minutes to a couple of hours depending on your experience.
Cortex advise against overhead pressing with this set. Keep it to presses, rows, curls, squats and the wide bench and floor work it's built for.
The 80kg total capacity gives you plenty of headroom for those movements as you get stronger.
What this means for you: If overhead pressing with a loaded bar is central to your programme, plan to keep a fixed barbell alongside this set for those lifts.
One set handles a dumbbell and barbell workout, which frees up the wall space a full dumbbell rack would eat. The stand keeps the whole system in a single, defined spot.
That makes it a sensible fit for a garage gym, spare bedroom or apartment training corner.
What this means for you: If floor space is your main constraint, an adjustable set like this does the work of a much larger collection of fixed weights.

Effort: one person can manage it; commonly 45 minutes to 2 hours, depending on the model. Exact time depends on your experience. Tools: spanner / wrench (bolts and fixings included).
You seat the handle in the stand, twist to select your weight, and lift. The RevoLock system with its patent-pending anti-jam curved guide picks up the plates you've dialled in. Dumbbells run 2kg to 40kg across 16 increments, so you're swapping load in a second or two instead of loading and unloading fixed dumbbells between sets.
Yes. The set includes 2 dumbbell handles plus 4 barbell steel tubes, so the same plates convert between formats. As dumbbells you get 2kg to 40kg per hand; assembled as a barbell you run 2.5kg to 41kg across 16 increments. One caveat worth knowing: it's not recommended for overhead use, so keep pressing to the bench or floor.
It ships in 3 cartons: one at 57cm x 56cm x 12cm (16kg) and two at 56cm x 37cm x 36cm (46kg each).
Anyone training at home who wants a full dumbbell rack and an adjustable barbell without a wall of fixed weights. With 32 adjustable combinations up to 80kg total, it covers beginners finding their working weight through to experienced lifters pushing 40kg per hand. The knurled steel handles give a secure grip when the load climbs. Best for: home strength training where space is limited.
One person can manage it, usually 45 minutes to 2 hours depending on your experience. You'll need a spanner or wrench, and the bolts and fixings are included in the box. Most of the time goes into building the stand and setting the plate trays; once that's done, the handles and barbell tubes are quick to sort.
It ships in 3 cartons with a combined gross weight of 108kg (with two heavier 46kg cartons holding the steel plates), so having a second pair of hands available on delivery day is recommended.
