The Dumbler Olympic


Can they be dropped?

Yes, however, only from knee height and on rubber flooring. Please be careful when dropping them, they might bounce and hurt you.

Can I do snatches and cleans with them?

Yes, the dumbbell is great to use in all types of Olympic lifts.

What plates can I use?

50mm Olympic standard weight plates.

Will there be a gap between the SlideLock and the plates?

Yes, that can occur, but it will not affect the user experience. Normal collars will usually slide or move during the exercise, while the SlideLock won’t budge, keeping you safe all through the workout.

Do they come in pairs?

The Dumbler Olympic is sold in pairs. Should you wish to only purchase a single dumbbell, please contact us and we will be glad to help.

Do the grooves on the dumbbells damage or chip the holes on plates at all?

No, the grooves are sand-blasted and smoothed over to make sure the edges aren’t too sharp, and to avoid damages or injuries.

Do the sleeves spin?

Yes, the sleeves come with bronze bushings, giving a reliable spin.

Are they awesome?

The dumblers are awesome!

The craftsmanship is incredible on these things, and I'm not worried about the weight plates slipping off and falling on my face.

My Favorite Piece of Equipment

These dumbbells are amazing. When I found out how much a set of fixed dumbbells would cost, I decided to do tons of research on loadable/adjustable options. So many pluses and minuses of every type, it was a tough decision. These were not cheap, but besides cost, they checked every box I wanted. They could do infinite increments of weights, they could use existing plates, and the collar system would work as strong as a screw on collar but far more conveniently. I reluctantly pulled the trigger (reluctant due to cost). My dumbbells have arrived, and I am SO happy I did. I love these things. They are an old person’s toy. The quality of the build is amazing, best built piece of equipment I have. The one complaint I did see in reviews…the amount of slop…is almost non-existent. I use them with rogue lb change plates that have a 50.4mm hole and rubber coating. Seriously, as good as no slop at all. Especially with the rubber coating, there is zero clanging and virtually no loose movement either. It’s a perfect combo. I’m incredibly happy with this purchase. Convenient, high quality, versatile. Love them.

I had seen in other reviews ppl mentioned getting a free shirt, so, kind of sad I didn’t get one lol. But maybe that was a temporary thing. If I had the money to spend I would upgrade my barbell too, but will need to save up. Maybe during next year’s Black Friday sale.

Training made easier

These dumbbells are exactly everything that they promise. Ultra secure clips, super easy to load, high-end finishes. I had honestly been eyeing them for months but couldn't justify ordering more equipment - until the old loadable DBs I was using dropped weight plates onto me mid-workout, really not a good thing for your floors or your personal safety! I'm so thrilled to never have to worry about that happening again, and even better - NO MORE COLLARS. Using the dumblers is a breeze, and so much safer! These are 100% worth it, I'm glad I made the investment and it certainly won't be my last.

Just get these.

I'm no elite athlete or power lifter. I'm a guy who has had the same pair of 25/35/42.5lb hex dumbbells for about 20 years now, since I was 15, and I have always had a regular routine of using them. During quarantine from pandemic, I got even more regular with my workout, and actually started to care about the missing weights in my collection. A loadable solution was most practical for the tiny corner of my home I'm willing to commit to weights, so I started trying out different 2" loadable bars. The Dumbler is simply the best loadable solution I have tried.

- It has a sleeve length which is not absurdly long, nor too short to load plenty of weight.

- It has a machining quality which you won't mind touching or looking at.

- It has good knurling! I always thought knurling was a bit of an esoteric concern until I encountered quality knurling on Gungnir and Rogue products during my shopping around. Turns out the "knurling" on my 15 year old heavily worn dumbbells is awful and I didn't even know it!

- They're reasonably priced for a low volume, carefully made, versatile solution.

Weights and bars last lifetimes. My original 25/35/42.5 dumbbells haven't even had their first refurbishing, they'll outlast me, even if they're not half as good looking for as fun to use as the Dumblers.

Buy once, buy something well made and practical, which you can stand to use and be around, and enjoy it. This is the kind of product the Dumbler represents. It's cheap if you commit to ending your…
