Vulcan Alpha Bumper Plates Review

Vulcan Alpha Bumper Plate Review - Versatile & Unique Basic Bumpers

I hate to ruin the surprise right out of the gate, but the Vulcan Alpha Bumper Plates are probably the most unique, versatile, and reasonably priced bumper plates currently on the market, and I’m extremely excited about finally getting to review them.

Of course, I realize that there are more exiting things to actually read about than bumper plates, but I truly believe that you’ll be glad to have discovered and read this review if and when you find yourself in the market for new plates – they’re about as close to the perfect bumper as it gets.

Alpha Review Intro

Vulcan Alpha Bumper Plate Set

Vulcan Alpha Bumper Plates with a set of V-Locks

The first thing that you should know about the Alpha Bumpers is that they are made using a completely different rubber compound than what is used for the run-of-the-mill virgin rubber and crumb rubber plates. Now I’m no rubber expert by any means, but it’s pretty clear that this new compound offers more advantages and more versatility than the classic materials – it’s almost as if Vulcan managed to find a material that unites all of the best features of the other bumper plate styles. The most notable of these features being:

  • durable enough to be used both indoors and outdoors (from mats and platforms to gravel, asphalt, and concrete.)
  • quiet enough to be used in gyms and boxes where noise is a serious problem.
  • high enough density to deliver a dead blow when dropped  – no bouncing and skipping around the platform like crumb rubber plates.
  • extremely accurate to claimed weight.
  • all the while being thinner than just about all other non-competition bumpers.

When you consider the above items along with the fact that Alphas are also colored, you can see why I say that they have all of the best features of the other plate styles – HI-Temps for their indoor/outdoor versatility, XFs for their noise dampening, basic bumpers for their slim profile and low bounce, competition plates for their accuracy, and then colored like stage plates. On top of all that, Alphas are priced very competitively – they sell for less than HI-Temps, and much less than Eleiko XFs or competition style plates.

Below is a chart showing set prices for the Alphas, HI-Temps, and XFs. These prices are pre-shipping, but it’s possible to get both the Alphas and the HI-Temps shipped for free (you’ll not be so lucky with the Eleiko plates). Also, set sizes do vary slightly so it’s not completely apples to apples, but the chart still paints a pretty clear pricing picture.

Alpha HI-Temp XF 
160 lb $310 $323  $314
250-260 lb $425  $498  $510
340-370 lb  $586  $667  $738


I didn’t compare the Alpha price to basic bumpers because basic bumpers don’t offer any of the advantages of the Alphas or the crumb rubber-style plates; like indoor/outdoor versatility or noise dampening. Interestingly enough though, while the smallest 160-pound set of Alphas runs about $40 more than the same size basic bumper set, that gap gets smaller and smaller as the set size goes up. Additionally, if you compare Alphas to colored basic bumpers you’ll see that Alphas are generally less expensive.


I own 320-pounds of Alpha Bumpers (no 10’s), and I put each and every plate on the scale to check for accuracy. I kid you not, every plate was spot on.

Full disclosure, my scale is accurate to within a tenth of a pound, so I cannot tell you that these plates are within 10 grams of stated weight or anything like that, but then again they very well could be – which would be pretty awesome considering no such claim is made by Vulcan. Perhaps someone else with a set of Alphas and a more accurate scale will chime in regarding the accuracy of their plates down in the comments section.

In any case, having every single disc in a non-competition weight set come in precisely at their stated weight is pretty impressive, at least as far as I’m concerned. It’s certainly the first time I’ve seen it happen among such a large quantity of plates.

Appearance / Color

Vulcan Alphas are basically the same mold shape as the standard black Vulcan Strength bumpers. The difference is in the rubber compound used and the specks of color in the rubber.

In the pictures the color specks make the plates look like crumb rubber, but when you see the plates up close and are able to touch them, you’ll notice right away that the plates feel much more like a regular bumper than a crumb rubber bumper. With crumb rubber there is a sort of rough texture that you can feel as you run your hands across the plate, and you can’t feel that with the Alphas – they are smooth and seamless.

Vulcan Alpha color flakes look like crumb rubber, but there is no texture - completely seamless

Of course the colors themselves correspond with the IWF-color scheme, with the 25’s being green, 35’s being yellow, 45’s blue, and 55’s red. There really is no color for a 10-pound plate, so like what most companies do, Vulcan went with grey.


Alphas have just the slightest bit more bounce than the high density, basic bumper plates, but it’s negligible. The real difference is between Alphas and crumb rubber plates. As you probably know, crumb rubber has a tendency to skip and bounce around the platform. There is none of that chaos with the Alphas – just a reliable, dead blow.

Indoor/Outdoor Versatility

Prior to the Alphas, the only plates that could consistently handle being dropped on abrasive, outdoor surfaces were the crumb rubber plates like the HI-Temps. Basic, virgin rubber bumpers are just too firm to be dropped on asphalt, gravel, and other uneven outdoor surfaces.

While crumb rubber is still a completely viable option for outdoor training and WODs, you still get to deal with the crazy bounce – bounce that can be even more unpredictable when dealing with uneven surfaces. Again, Alphas don’t have that insane crumb rubber bounce – they dead blow like a basic bumper.

Don’t get me wrong, I’m not trying to convince you that Alphas are 1000x better than crumb rubber when it comes to the outdoor use thing, but because of the low bounce, IWF colors, lower price, and the fact that Alphas don’t flake apart like crumb rubber tends to, they definitely are somewhat better.


The Alphas have a stainless steel, hooked insert. Hooked inserts are basically a normal insert with welded rebar that the rubber of the bumper gets molded around – the point being to create a more permanent and improved bond between insert and bumper. What this means to you as an Alpha owner is that your bumpers are unlikely to ever have an issue with insert separation. Sure it’s not the most common bumper issue, but it does happen and it’s always nice to know that it’s been addressed. You’d be surprised how few companies bother to use hooked inserts by the way.

The Vulcan Alphas have a hooked insert that sits flush with the rubber rather than above the surface of the plate - this reduces insert on insert friction

It’s also worth noting that the inserts sit flush with the surface of the plates. When you have plates stacked against one another on the bar, there isn’t excessive rubbing and wearing down of the inserts themselves. Many cheap bumpers (and even some of the nicer plates) have the inserts actually sitting above the rubber surface, and this slowly wears down those inserts. Again, not the hugest issue to have, but at least it’s not going to be your issue.

Low Noise

Vulcan Alphas have the advantage of being about 30% quieter than virgin rubber plates when dropped from an overhead position. That 30% figure is Vulcan’s based on tests they did with a decibel meter, which I cannot confirm, but I can confirm that they are indeed noticeably quieter. I’d say that they are about as quiet as XFs (for those of you who have used those in the past), but without the excessive width, unpredictable bounce, and unjust price.

Reducing the noise that comes from a dropped barbell is important for a lot of lifters, personal trainers, and coaches. Garage gym owners have neighbors and families to think of, and many CrossFit boxes share walls with retail shops. Prior to the Alphas, your only real choices for quiet bumpers were HI-Temps and the aforementioned XF. HI-Temps are thick, bouncy, and slightly more expensive – and not that much quieter than basic plates. XFs are certainly a quiet plate, but they are insanely thick, over-priced, and carry a garbage warranty.

With the Alpha, you get the quiet plates at a reasonable cost. On top of that, you get a normal plate thickness, less bounce, and even added color. I have no problem with HI-Temps or XFs from a functional standpoint, nor do I worry about their durability (for the most part), but I’d be lying if I said they compared to the Alphas when it comes to features and price.


You know that nasty smell when you get new bumper plates dropped off? That horrible, lingering smell that forces you to store your plates outside the first week or two? Well that smell does not exist on the Alphas. As I mentioned, Alphas are made from a completely different rubber compound, and while they don’t smell like roses or bubble gum, they certainly aren’t offensive like virgin and recycled rubber, and what little smell there is dissipates in days instead of weeks.

That said, there is a thin layer of silicone on the plates that you need to wipe away with a rag and some soap, but as you probably know from other rubber products, that’s pretty normal. That silicon is put on deliberately at the factory to protect the rubber from discoloring and blooming as it oxidizes. Pretty normal stuff.

Plate Width & Diameter

Alpha Bumpers are the same 450 mm diameter as any other Olympic bumper plate. The only exception to this is the 10-pound Alphas, which are closer to about 400 mm in diameter (below image has the 10’s stacked on the 25’s).

Vulcan Alpha Bumper Plates - Size difference between 10's and the rest of the set.

This is very interesting to me because with pretty much all other bumper plate brands and styles, the skinny 10-pound plate is by far the most fragile and the most likely to fail. It’s also the plate size that comes with the worst warranty. All Vulcan did with their Alpha 10’s is take 11-12% or so off the diameter of the plate and add that material back to the thickness of the plate. Now you get a pair of 10’s that is only moderately smaller, more durable, and much less likely to ever need to be replaced. And yes, they can be used for technique purposes.

In terms of the thickness of each plate, I’ve attached the dimensions in the chart below. You’ll notice that not only are Vulcan Alphas thinner than the HI-Temps and XFs, but also marginally thinner than basic plates as well. By basic, I am referring to standard bumper brands like the HG, AB Sports, and so on – these brands and models all share just about the same overall plate dimensions.

 Bumper Plate Widths Vulcan Alphas Basics HI-Temps Eleiko XFs 
10-lb 1.17″ 1.00″  1.375″  1.25″
25-lb 1.81″ 2.00″ 2.25″ 2.75″
35-lb 2.55″ 2.75″ 3.175″ 3.75″
45-lb 2.95″ 3.25″ 3.75″ 4.75″
55-lb  3.34″ 3.75″ 4.75″

* Vulcan Strength didn’t round their Alpha plate widths for the product description like everyone else seems to have done, so I didn’t either.

The width difference between a basic 45-pound bumper and the 45-pound Alpha is negligible

So what difference does the plate width mean anyway? Thinner plates are generally considered better because you can load more plates on the bar, you can store more plates per plate storage horn, and they are less cumbersome to move around the gym. Sure 45-pounds weighs 45-pounds, but does it seem easier to move around a 3″ wide 45-pound plate, or a nearly 5″ wide 45-pound plate?


The warranty for Vulcan Alphas is amazing, and also very specific. You get 1-year on the 10-pound Alphas, 3-years on the 25-pound Alphas, and 4-years on every other plate size. This is hands down the most competitive warranty for non-competition bumper plates that I know of.

In the basic bumper plate market, a good warranty is a full year on the 10 and 15-pound plates, and 3-years on the 25-pound plates and above – you can find this warranty from a handful of the more reputable bumper vendors. However, the industry norm seems to be about a year on the whole set, with there commonly being a shorter 3-6 month warranty on the lighter 10’s and 15’s. Eleiko, for instance, offers only a year on their premium XF Bumpers, and that 1-year doesn’t even include the 10-pound plates.

All that being said, I feel as though I should remind everyone that you simply will not destroy 25+ pound bumper plates without literally setting out to do so, and about the only situation in which I can see a 10-pound plate being thrashed within the first year is if you are using them in lieu of technique plates in an Olympic training center or newbie CrossFit box – which you really have no business doing. Frankly, if you teach the Olympic lifts to new lifters, invest in some tech plates – that’s what they’re for.

At the end of the day I’m impressed with the Alpha warranty – it’s extremely generous, and better than what you’ll get on any other basic bumper plates.

Alpha Bumpers Review Summary – Pros & Cons

Vulcan Alpha Bumper Plates - Fantastic bumpers for Olympic lifting and CrossFit

+ Pros

  • Alphas are extremely accurate to stated weight – it’s like lifting with competition plates at a fraction of the price.
  • Just as quiet as Eleiko XF crumb rubber plates, but not nearly as thick, cumbersome, and expensive. Alphas also won’t flake apart like crumb rubber tends to do.
  • Alpha bumpers can be used both indoors on platforms and rubber mats, or outdoors on concrete, asphalt, and gravel without any risk of damaging the plates. Virgin rubber and recycled rubber plates cannot handle being dropped on these abrasive and uneven surfaces for any length of time.
  • The price for Alphas blows away the price you pay for HI-Temps or Eleiko XF; the only other models that are both quieter than virgin rubber plates, and suitable for outdoor use. Not only is the price better, but the Alphas are slimmer and include IWF colors.
  • Alphas have a dead blow much like virgin rubber plates – no erratic bouncing. Compare that to the crumb rubber plates that bounce and skip all over the place (HI-Temps are especially known for their crazy bounce.)
  • The famous odor associated with new bumper plates doesn’t exist on new Alphas. They do have a slight odor, of course, but it’s nothing compared to virgin rubber, and it dissipates quickly once removed from their packaging.
  • Vulcan opted to use the the anchored insert in the Alphas. This goes a long way to prevent insert separation, and it’s a feature that none of the crumb rubber plates have. The insert is also seamless, which is pretty normal – save for the Eleiko XF.
  • The Alpha warranty is solid – much longer than the industry average for basic bumper plates.

– Cons

  • Technically Alphas cost more than basic black bumpers, but so long as you buy 260-pounds or more, the difference becomes negligible. Plus, if you look at all the pros, that price difference seems meaningless anyway.
  • When the heavier plates are lying flat on the ground, there isn’t much of a bevel to get your fingers under when you go to pick the plate up. This is becoming oddly common I’m finding.
  • There are no 15-pound Alphas. Personally I don’t think that a 15-pound plate is all that important, but who am I to make that decision. Some folks like 15’s so their absence will be a con.
  • Alphas are out of stock more often than not. This speaks to their popularity, but waiting for a product that you wanted in your gym yesterday does suck, and is a drawback.

I don’t want to sound like a salesperson, but there are really no significant drawbacks to Alphas. It’s very rare that a new product offers this much versatility and value without a significant drawback or three, but I’m just not finding anything negative here. I’d have to start making stuff up in order to bad-mouth these plates, and of course I see no reason to do that. Fact is, Alphas are solid.

Then again, if you don’t care about noise, accuracy, training outdoors, or any of those other perks I discussed, I certainly wouldn’t fault you for sticking with basic bumper plates. But if any of those features are important to you, I think that you’ll find that the Alphas are the way to go. I just don’t see anyone regretting an Alpha Bumper purchase.

    Vulcan is a strong company. I have the Elite and some black bumpers and want to pull the trigger on the new Power Bar. I am in VA., so basically I get free overnight delivery. I hope as a company they grow because their shit is legit. The deals with the bar and bumpers are good deals, especially when they are out of stock and they offer pre-order discounts. I got turned on to them because of your reviews and thank you for that.

  • Tony June 5, 2016, 8:54 pm

    This definitely sounds like my pick for bumpers when I need to add more weight. The inside/outside capability combined with all of the features that make OFW/Vulcan black bumpers top-of-the-line make it kind of a no-brainer.

    Really cool to see Vulcan innovating like this. Just curious, have you tried using this outside on a rougher surface? Can you verify that they’d hold up on par with hi-temps?

    • jburgeson June 6, 2016, 2:02 am

      I did use them outside, both on concrete and asphalt, but no dirt or pebble surfaces. They got super grungy of course, but they didn’t get cut up or shred pieces of rubber, and they wipe clean and look brand new. Matter of fact many of the pictures were taken towards the end of the review, but you can’t tell they were even used once I cleaned them up. I can’t tell you what they’ll look like a year from now since I haven’t had them that long, and I alone cannot put the kind of miles on them that a box could, but everything seems to point to good news.

      I know a good number of readers already have the Alphas. Maybe some of them will have used them on a larger variety of surfaces and be able to offer some feedback.

  • Kat Lee June 6, 2016, 5:31 pm

    I’ve used the Alphas outside on cement and tarmac and they hold up great!! There isn’t any cracking or any damage to the rubber even on a rougher surface. They look and feel just as smooth, shiny, and brand new as when I got them out of the box.
    Friction between the plates and ground while loading/unloading the plates on and off the barbell (you know, pulling/pushing them off and scraping them on the ground), didn’t leave any noticeable damage or abrasions to the rubber.
    All and all, these are awsome plates and by far my favorite to use. They will not disappoint and are well worth the reasonable investment!!

  • Justin June 8, 2016, 9:40 am

    Nice review. I strongly considered getting the Vulcan plain black bumpers, but they were out of stock for a long time. Especially because they used to offer a set that let you pick a pair of 10s, 25s, and 3 pairs of 45s without 15s or 55s. I ended up going with mostly used iron (lucked out on some Ivankos) and 160lbs of Rogue Echos. As I infrequently use bumpers, the Echos are fine, but these look like they would have been a great alternative. The splash of color, in appropriate IWF color scheme, is nice since most home gyms are pretty much all black.

    • jburgeson June 9, 2016, 9:11 am

      They still have that 3 pair of 45’s set I believe. I think you ditch the 35’s and 55’s for the extra two pair of 45’s, if my math is correct anyway.

  • Hyden July 17, 2016, 9:22 pm

    These look awesome and I’m considering buying a set along with a Rogue Ohio bar, that combo sound good?

    • jburgeson July 17, 2016, 9:32 pm

      Yeah both are great products, definitely. For CrossFit?

  • Casey July 21, 2016, 11:21 am

    How have you dealt with the shipping of the bumpers? Did you pay for the lift gate service?

    • jburgeson July 21, 2016, 12:51 pm

      Yes I have, and no I didn’t. Each bumper is in its own box, so they can just be picked up one by one and put on their hand cart.

  • Sky August 22, 2016, 3:01 pm

    Do you recommend these bumpers over the OFW bumpers over at Fringe? I’m about to pull the trigger on a colored OFW bumper set (for home CrossFit setup) but then I saw this Vulcan review on your site and now I’m wondering what the best option is at this point.

    • jburgeson August 22, 2016, 3:11 pm

      If you’re willing to pay the difference, they are a better plate, but the OFWs will still be fine. It might not matter though because the Alphas are very hard to catch in stock. Noise levels are night and day though, so if that matters you may want to hold out for the Alphas. Other than that, both will last.

  • Mark August 29, 2016, 2:48 pm

    Are these plates made in the USA? Usually that’s an advertising point but I couldn’t find it anywhere. Looking to pair with Rogue equipment.

    • jburgeson August 29, 2016, 3:05 pm

      No they are not made in the USA, and neither are any of the Rogue bumpers save for the HI-Temp crumb rubber plates. Bumpers are just one of those items you almost have to accept as being imported, or be willing to buy a lesser product for potentially more money.

      • Mark August 29, 2016, 7:57 pm

        Thanks for confirming my suspicions. Having a second opinion is huge.

  • Tao-Nhan Nguyen September 15, 2016, 8:07 am

    Just came across your article, great work.
    So far I thought the Hi-temps were the quietest plates around but your article seems to point otherwise. Just to clear things up, in terms of noise, are the Vulcan Alpha plates quieter than both hi-temp and XF plates ?

    • jburgeson September 15, 2016, 8:10 am

      That is correct, and with less bounce.

  • Matt December 12, 2016, 11:59 pm

    Any possibility of doing a test for sound? I’m curious how the Vulcan Alpha, Eleiko XF, and standard bumpers (or hi-temps since they’re common enough as reference plates) differ. Can you record a video of dropping say 135lb/185lb/225lb from overhead (jerk) with the phone at a set distance?

    • jburgeson December 13, 2016, 10:13 am

      I don’t have the XFs anymore. I have to get rid of stuff from time to time in order to have room for new stuff, and well, the XFs took up a lot of space.

  • Paw April 7, 2017, 9:00 pm

    Does anyone want to split a a set with me? the price of the plates will be cheaper if we buy more + we shipping would be split. I’m in the Los Angeles, CA area.
