(Deep movie trailer guy voice) “In a world where rubber dominates the bumper plate arena, a West Coast company revolutionizes the game with a different type of product…”

I’m listening…

“…one that offers sex appeal, impressive performance, and downright amazing stamina…”

Sounds exciting, go on…

“…and leaves you feeling as if you’re king of the world…”

Yes, uh huh? Asking for a friend…

“… as if you’re a bird, you’re a plane… no wait… URETHANE!”

Ahhhh… I see what you did there.

(resumes normal broadcast)

Ladies and gentlemen, the American Barbell urethane plates have indeed revolutionized the bumper plate market.

Their unique characteristics and physical attributes make for a different type of lifting experience.

They are some of, if not the most durable plates available, they look incredible, and they perform at a very high level.

In this review, I’ll go into detail as to why urethane, and specifically the American Barbell urethane plates, belong in the discussion as top dog.

Why Urethane

When it comes to bumper plates, rubber is far and away the most common material. It’s relatively inexpensive, it’s easy to work with, and it’s pretty durable.

On the other hand, you’ve got Urethane, which offers two primary benefits over traditional rubber:


With the right formula, Urethane is simply superior to rubber when it comes to durability. It resists cuts and tears better than rubber, and it has better compression qualities that help resist deformation. Unlike rubber, which is biodegradable, urethane can also be formulated to be more resistant to sunlight, weather, and other elements. Lastly, and important in the bumper plate application, is that urethane maintains its properties, regardless of its durometer (hardness) rating. The higher the durometer rating, the lower the bounce. With rubbers that are compounded to high ratings (90+), their physical properties can actually be compromised, which may lead to issues over time.

Have you ever wondered why most rubber bumper plates look the same color-wise? I’m not talking about the IWF standard plate color system, but the actual color itself. It’s because rubber cannot be dyed. In fact, the color of rubber actually comes from a clay filler. Urethane, however, can be dyed. Not only that, but it can be perfectly color-matched to whatever your heart desires. It also makes it very easy for commercial/team applications because a logo can be injected with no loss of quality.

The downside to urethane is that it’s more costly, but as you’ll read below, that may be a worthy trade-off depending on your needs.

American Barbell Urethane Bumper Plates

The American barbell urethane plates are my personal favorite bumper plates that I’ve ever used.

I absolutely love the way they look, I love the way they perform, and I love the fact I’ll never have to worry about them wearing out. Who knows, maybe I’ll pass them down to my grandkids one day!

The specs on the plates are what you would expect with a premium offering. They’re made with quality materials and they’re built with IWF standards in mind.

Overall Construction

The American Barbell urethane plates are unsurprisingly made with urethane. The urethane is sourced from Germany and the plates are manufactured in China, where cost of production is lower. While American Barbell makes much of their equipment in the United States, it is extremely cost prohibitive to do so with a urethane plate. American Barbell also has an international patent on the urethane bumper, but because of the time it takes to litigate in China, it makes it difficult to enforce. For the record, other urethane manufacturers are also producing their plates in Asia. From my understanding, and from looking at the specs of competing plates, other urethane bumpers are not re-branded American Barbell plates.

The plates are built to be consistent with IWF standards, although the plates themselves are not IWF certified. As of the time of this review, no other urethane plate on the market is IWF certified.

The inside of the plate is a solid cast iron core with a 140mm hard chrome center insert. This insert is constructed with one piece, which keeps the hub tight and secure to the rest of the plate. Unlike a rubber competition plate that has anywhere from 4-6 locking bolts, this plate requires less maintenance/tightening. It also makes for a nice, clean look.

American Barbell vs Rogue Fitness Garage Gym Lab

In the past, American Barbell used a different hub style. As you’ll notice in the picture below, the Rogue Fitness model uses that same (old) style. Intek Strength does as well. Today, American Barbell uses the updated hub style (left picture) that is one smooth piece with a perfectly beveled edge. The other manufacturers continue to use the old design with the exception of Hammer Strength.

Lastly, two raised flanges surround the center hub and border the outer edge. These flanges protect against metal-on-metal contact for added protection and they allow for easier gripping of the plate.


I’ve received some questions on whether or not these American Barbell urethane plates are as accurate as a competition style bumper plate. Although American Barbell doesn’t explicitly claim a tolerance threshold, you’ll be happy to know that the plates are extremely accurate.

After weighing them on a calibrated scale, the results were as follows:

  • 55 lb plates: 55.1 lbs & 55.1 lbs
  • 45 lb plates: 45.2 lbs & 45.2 lbs
  • 25 lb plates: 25.2 lbs & 25.1 lbs

My plates are all well within +/- 1% of the claimed weight, which is very tight. In fact, they all meet IWF requirements.

Plate Thickness

When it comes to choosing plates, especially bumper plates, thickness is a really important consideration. If you’re lifting more than 405 lbs, you really need a thinner profile plate. Hi-Temps, for example, are simply too thick to add enough weight. Not only that, but they also disperse the weight differently.

Generally speaking:

  • Thin plates = more weight on the bar & less bar flex
  • Thick plates = less weight on the bar and more bar flex

Some of this will depend on the type of bar you’re using, the amount of weight you’re lifting, etc… but thinner plates are undoubtedly the better option.

With regards to the American Barbell urethane plates, the thickness is great. Depending on the weight of the plate, the urethane plates are actually thinner than competition rubber bumpers. This is true on 45 lb and 55 lb plates, while the 25 lb and 35 lb plates are slightly thicker.

In the chart below, you’ll see a comparison to the different styles and brands of bumper plates. The numbers referenced below are directly from the manufacturer, but they may or may not be entirely accurate. For example, the Rogue competition bumper plate states a thickness of 2.15″ on the 45 lb plate, however, my set is actually 2.23.” Minor differences aside, this will give you a good idea of what to expect when looking at the plate profile.

After measuring my American Barbell set, my findings were as follows:

  • 55 lb plates: 2.25″ & 2.25″
  • 45 lb plates: 2.05″ & 2.05″
  • 25 lb plates: 1.53″ & 1.53″

This is very close to the stated thickness. The 55 lb plates are actually slightly thinner than the stated 2.27″ and the 25 lb plates are slightly thicker than the stated 1.50″. At these numbers, and assuming a typical 16.25″ sleeve, you can load well over 600 lbs on the bar with enough room for a collar at the end.

Unless you like chasing barbells around the gym, protecting your face from bouncing bars, or having to constantly reset positioning, low bounce plates are ideal.

In the equipment space, this bounce is measured by the shore durometer rating, which is a rating from 0-100. It actually measures hardness. The higher the rating, the harder the material, the lower the bounce. Hi-temps, which are extremely bouncy, sit around a 75, while competition rubber plates are in the low-to-mid 90’s. The American Barbell urethane plates come in at the upper 80’s, which is good for a very low bounce. I’ve actually seen very little difference in the bounce of these plates and the higher durometer-rated Rogue competition bumpers (94).

As mentioned earlier, urethane is superior to rubber when it comes to durability. These American Barbell plates are built to last for a very, very long time.

Traditionally, companies will drop test their bumpers at least 5,000 times, but not many drop them much more above that. Eleiko, for instance, drop tests their world-renowned competition discs 5,000 times. Rep Fitness has actually drop tested their competition plates over 30,000 times. Still, nobody tests drops like American Barbell.

After drop testing well over 50,000 times from 8.5 feet, there were no issues of any material concern with the AB plates – only cleaning was required.

Now, if you’re in a garage gym training alone or with a few buddies, this probably isn’t that big of a deal. It will take a while to even hit the minimum drops that some companies test. If, however, you’re in a facility, this could have a big impact. When American Barbell polled several of their facility clients, they learned that they were hitting between 3,000-5,000 drops per month! Even at the low end of that range, they’re breaking through the minimum drop test before 2 months’ time.

To be clear, I’m not suggesting that Eleiko competition discs are going to start breaking down after 2 months (or 5,000 drops), because they’re not. They’re highly reputable and they’re a great product. What I am suggesting though, is that the American Barbell plates are going to have a longer life, and possibly a much longer life. They’ve tested their bumpers with exponentially more time under stress, which gives me a great deal of confidence that they’ll stand the test of time.


Oh my God, Becky, look at those plates!

That was basically my reaction upon opening these beauties. Unless you prefer the more traditional colors of rubber plates, you’ll be hard-pressed to find a better looking set of bumpers.

The colors on the American Barbell urethane plates are stunningly vibrant. I for one really appreciate the fact the colors are different than the norm. The ability to dye urethane is a distinct advantage in the aesthetics department compared to rubber, and AB knocked it out of the park.

I’m a big fan of how they chose to do the lettering. Normally I prefer the stark contrast between white lettering and a plate color, but American Barbell’s subtlety is a really nice touch. The words “American Barbell” are actually the same color as the plate, but because the lettering is raised, it gives a cool 3D look. Conversely, the numbers are painted in gray, which is also unique and cool looking.

I really love the smooth chrome center hub. I think it looks much better than the old design. It gives the plates a more high-end look and feel, in my opinion. The slightly raised pebble pattern on the urethane itself also provides a similar effect. It reminds me of the pebble-grained shoes that scream luxury.

The one thing I wish American Barbell did on the pound plates was to add “LB” in the same manner they did “KG” on the kilo plates. I understand the reasoning why they did this, but I love the way the KG plates look, and I think the LB would be a welcomed change.

Overall, the uniqueness of these plates just draws you in. I find myself wanting to lift with these just because they look so badass.

10/10, would stare at again.
