Vulcan EZ Curl Bar Full Review

Vulcan Curl Bar Review

When I heard that Vulcan Strength was going to offer an EZ curl bar, I was intrigued. When I finally saw the specifications and the very low $139 price tag of that curl bar, I knew that I had to get my hands on one and check it out. So I did, and this is my take on it.

In this review I will cover all there is to know about the Vulcan EZ Curl Bar so that you can decide if this is the right curl bar for you. I’ll list all the bar’s specs, discuss the overall feel and performance of the bar, and compare it to other curl bars along the way.

Vulcan Curl Bar - knurling and black oxide - camber view

The knurl pattern used on the Vulcan Curl Bar is appropriate; as is the depth. It’s not overly aggressive but also not too soft. It’s just right. Grip quality is even further enhanced by the use of black oxide; a finish that is very reminiscent of bare steel. This bar offers a solid grip, and unless you just sweat excessively chalking up should be optional.

The Vulcan Curl Bar is also fully knurled save for a 4″ gap in the center. This means that should you ever want to take a different hand position than the default bicep curl or tricep extension positions, your hands will still find knurling. It probably won’t happen often but at least it’s an option. Most cheap curl bars (and even some of the nice models) are not fully knurled.

Camber Comfort

The cambers around the default hand position for bicep curls are just perfect. Rather than being gradual curves, the angles are more pronounced, which result in a little nook for the hands to rest against. This not only stops the hands from shifting or sliding down the bar, it also eliminates the sensation of the hands moving; which can be just as annoying.

The Vulcan is also well balanced, and by that I mean it doesn’t rotate or “correct” during the first couple reps like some curl bars. When I go to pick up the Vulcan, the position that my hands find naturally is the same position they stay in during the entire set. Having a curl bar that wants to self-adjust and find equilibrium isn’t that big of a deal since it won’t shift again once that’s happened, but there’s something to be said for not having to deal with that at all.

On the flip side, the outer camber where you would grab for wide-grip curls is shorter on the Vulcan, and a little less user-friendly because of the sharp angle right where the center of your hand would be. The bend is more gradual on the Rogue Curl Bar – almost straight. I personally don’t use this position on the curl bar so I don’t care, but you may.

The image below illustrates many of the differences in camber angle that I’ve discussed.

Variety of EZ curl bar shapes. The sharpest angles feel the the most secure in my personal opinion (from top Vulcan/Rogue/CrAP)

Bar Weight

The unloaded weight of the Vulcan Curl Bar is about 25-pounds – a solid starting weight. Many of the cheap box-store curl bars have ridiculous weights; weights that force us to do 3rd grade math rather than 1st grade math to determine totals. For example, the XMark EZ Curl Bar is 22-pounds, the CrAP Super Curl Bar is 18-pounds, and the Marcy EZ Curl Bar is 13-pounds! Maybe it’s just me and my OCD, but 5-pound increments please. Also, the super light bars are hollow, and that’s not great.

Sleeve Assembly

The Vulcan Curl Bar has sleeves that rotate on a pair of bronze bushings, much like any other high-performance barbell. In addition to the bushings there is also a single bearing per sleeve. The bearing is pretty much just a rotation bonus; it’s not necessary at lighter loads, but it will help eliminate resistance at heavier loads. It’s a nice touch that obviously didn’t have a major impact on the price of the bar.

The Vulcan Curl Bar is a bushing-based bar with one additional bearing per sleeve

The sleeve assembly is held together with snap-rings. Unlike the hex bolts found on many cheap curl bars, snap-rings do not require any maintenance, and are not at risk of failing.

Sleeve Length

The Vulcan EZ Curl Bar has very long, 11¾” sleeves, giving it the most loading capacity of any EZ curl bar that I know of. Now I went on and on about how lengthy the sleeves of the Rogue Curl Bar are when I reviewed that bar a few months back, but here we are with the Vulcan and it has even longer sleeve still. This is an even bigger improvement over basic economy curl bars with their 6″ to 7″ sleeves.

The benefit of having long sleeves isn’t about loading the bar up with 500-pounds of steel plates like you were going to deadlift it or something, it’s about being able to load up the bar adequately using your existing plates; which often times includes thick bumper plates. When you’re dealing with an economy curl bar with short sleeves, you run out of loading space after just one large bumper and your collars. That’s lame. You’ll never have space issues on the Vulcan Curl Bar, even if you only own the super-thick, classic HI-Temps.


The shaft of the Vulcan Curl Bar is treated in black oxide. Black oxide is generally chosen as a finish when price and grip security are considered more of a priority than oxidation resistance. Black oxide has a very natural and grippy feel; much like raw steel bars, but it offers very little in the way of rust prevention. It feels great, but it will require maintenance.

The sleeves are finished in hard chrome, which as you know offers excellent protection from oxidation. It’s also one of the most durable finishes.


How does the Vulcan Curl Bar compare to other curl bars on the market? Well let’s see!

Vulcan vs box-store curl bars

Imported, box-store curl bars are cheap. They tend to have hollow shafts, drawn on knurl, flaky chrome, and short sleeves. They also have odd weights, random diameters, pinned sleeves, and many of them don’t even have bushings – just a loose fitting sleeve bolted to the end of the hollow shaft. With few exceptions, box-store curl bars are pure garbage.

If you already own a cheap curl bar and it serves your purposes, by all means drive it until the wheels fall off. If you’re tired of the limited weight, your plates not fitting on the sleeve, the lack of grip, or doing math to figure out what your 13-pound bar weighs once loaded, maybe it’s time for a better curl bar.

When it comes down to it there is no comparison between a cheap, box-store curl bar like CAP, Marcy, Body Solid, and so forth to the likes of Vulcan, Ivanko, American Barbell, and Rogue. One group contains very durable, fully-functional, high-quality bars, and the other contains impulse-buy bait for those uneducated about quality equipment.

Cheap CAP curl bar - flaky chrome, rust, insignificant knurl, sleeves too thick for bumpers, no bushings, and on and on - garbage

Note: If personal finances prevent you from spending $139 or more on a curl bar, try to utilize the information found in these reviews to get the best possible equipment for your money. So long as you know what to look for/avoid in box-store equipment, you should be able to filter through the worst options and find something you can live with until you can afford to upgrade. 

Vulcan Curl Bar vs the Rogue Curl Bar

Rogue Curl Bar versus the Vulcan Curl Bar

Both of these are amazing curl bars. Performance-wise there seems to be no significant difference. They both offer a great grip on 28.5 mm shafts, sleeves that rotate smoothly, and unlimited weight capability; at least for curl bars.

There is no standout in terms of durability either. They both have solid steel, very strong shafts, genuine bronze bushings, and the same 5-year warranty. I would be happy lifting on either of these for the rest of my days.

There are some minor differences though, and I’ll list them out below.

  • The Vulcan’s shaft is more likely to oxidize because of the black oxide finish, but the black oxide shaft is naturally grippier, and the rust can be avoided with upkeep.
  • Rogue’s e-coat finish will retain its color longer.
  • In addition to bushings, the Vulcan has a bearing in each sleeve which can help with rotation under extreme loads.
  • The shape of the bars are slightly different. You get to decide which is better for you.
  • The Vulcan has slightly longer sleeves.
  • The Rogue is $199 plus shipping while the Vulcan is $139.99 shipped.
  • The Rogue is an American-made product while the Vulcan is made in Asia.

Vulcan Curl Bar – Review Summary

The Vulcan Curl Bar is a hell of a deal at $139. It has a great knurl, perfect cambers, long sleeves, solid rotation, a good weight, and a fair warranty. It’s competitive with all three bars from the above table, yet it costs a fraction of their cost. It even ships for free. Unless you’re adamantly opposed to buying equipment that is not made in the USA or you simply refuse to oil and maintain equipment, I can think of no reason not to own this curl bar. It’s a steal.

If you found this review helpful, please show me some love by sharing it. I don’t even care where. Happy lifting!

    Wow!! You got this up quick. Thanks for such a thorough comparison.

    • jburgeson August 13, 2017, 1:00 pm

      Of course! Thank you.

  • Jim L August 13, 2017, 12:41 pm

    I actually like my Xmark bar very much, and since i lift in kilos, the bar is easy as it’s 10kgs. The knurling is fairly aggressive on it, but anyone who lifts regularly will have hands tough enough to handle it without whining. It’s also plenty sturdy for my relatively weak lifts.

    I’ll use it until it dies and then I’d likely choose between another Xmark and the Vulcan bar. The Vulcan bar seems like a great piece of gear at a reasonable price point. Definitely hard to beat.

    • jburgeson August 13, 2017, 1:01 pm

      If it dies, you can’t buy the same bar again – because the bar shouldn’t die!

    • Rob H August 13, 2017, 1:04 pm

      I have the XMark 3677 Commercial in black manganese phosphate and I think that it’s a pretty solid bar also. If it weren’t for the incomplete knurl on the bends I would give the bar an A. This Vulcan bar looks like a beauty and the price is right. I love that we have a Rogue alternative that matches their quality but offers much better value.

      • jburgeson August 13, 2017, 1:13 pm

        I’ve seen that XMark. It’s not an awful choice – pretty decent compromise between the total garbage and the higher-end bars. It outta last for a good while unless you wear through the brass bushings somehow. It has some standard box-store features like short sleeves and weak cambers, but you could do a lot worse for sure. Also, if not a lot of weight is being used, the downsides are less of an issue. Easier to grip and less likely to shift in the hands, no running out of sleeve space, etc. Yeah like you said, ride it until it breaks; maybe it never will.

  • Colt S August 14, 2017, 2:42 pm

    I am super thankful for this review. I have been waiting forever for an alternative to rogues curl bar and trap bar. I will pick up this curl bar for sure. As for the trap bar, did you see the new one Vulcan came out with? What do you think? It’s quite a bit cheaper than rogues with both handle positions.

    • jburgeson August 14, 2017, 4:43 pm

      I’ve seen it but not physically handled it. It’s a big improvement over their previous trap bar though.

      Seems to me all the new specialty bars from Vulcan are top notch and priced very competitively. I’ll be checking out the safety squat bar soon. If that’s half as good as the curl bar, I’ll probably be pretty supportive of the whole line.

  • Randall August 14, 2017, 5:00 pm

    I’m anxious for your review of their new Swiss bar with chrome sleeves. That looks good…!

  • JuRiel August 18, 2017, 9:15 pm

    I just checked the bar on their website and the price increased to $279. I guess good things dont last forever. Well, if this is their actual new price and not a typo, the Rogue curl bar will be the route for me. Great review!

    • jburgeson August 18, 2017, 9:21 pm

      Oh wow, I’m gonna email them about that. That can’t have been done on purpose. Thanks for letting me know

    • jburgeson August 18, 2017, 11:16 pm

      The price was obviously meant to be changed, but not to that. It’s been “corrected”.

      • JuRiel August 19, 2017, 5:31 pm

        I figured something was up with the significant price change. It is odd because the price changed twice but is back to $139.

        • jburgeson August 19, 2017, 5:33 pm

          Yeah the 149.99 was just them mis-remembering what it was before. That price change I guess was meant for a totally different product altogether. It’s all back to normal now.

  • Eric September 18, 2017, 2:42 pm

    Really helpful detail. I have a lot of rogue gear so comparing stuff to that provides a helpful point of reference and this vulcan curl bar seems to stack up. Like the price point too.

  • SteveL October 13, 2017, 5:11 pm

    Did you try doing lying tricep extensions with this bar? How was hand placement if you did?

    • jburgeson October 13, 2017, 5:30 pm

      Yeah I do tricep extensions as often as I curl with it. It’s perfect as far as I’m concerned. That is, I’ve never thought ‘Gee I wish this bar…’ It’s a great curl bar.

  • Jason October 24, 2017, 11:01 am

    I’ve had a my Vulcan Curl Bar for a little while now and I love it. I’ve stopped using my cheap curl bar AND my cheap triceps bar. I’m an aging lifter who’s quit most vices so lifting weight at home is how I get my kicks and using quality gear makes my life that much more enjoyable. I also have the Vulcan Standard and the Rogue 2.0. Both great bars. I got he Vulcan Standard based on this website’s review. Love this website.

    • jburgeson October 24, 2017, 11:38 am

      Thanks Jason! I appreciate that, and I’m glad you’re happy with those purchases.

  • Chrisi April 12, 2018, 8:55 am

    This is a really nice bar for the price. I really like Vulcan products and I have had a great experience with their customer service. Thank you for the Garage gym review as it was very helpful when making my decision. I put a review up on the Vulcan site for this bar….

    Aww yeah! Loving this bar! Knurl is pretty passive but grips decent enough for some hot accessory work after squats, deads and good ol’ bench press. The angles are slightly more extreme than your typical big box gym curl bar but that is a good thing. Comfy on the wrists for close grip and wide grip work. Excellent bar for the price and Vulcan has a repeat customer. My biceps got bigger just by having it in my house.

  • Matthew Rogers May 15, 2018, 12:37 pm

    If like to buy one based on your review, but it has been out of stock for a long time and they won’t tell me what the ETA is. Do you have any pull to find out what’s going on with this product?

    • jburgeson May 15, 2018, 2:27 pm

      Hey Matt, I asked and was told 1-2 weeks.

  • Victor Arguijo May 24, 2018, 7:27 pm

    What’s the advantage of a racckable curl bar? Im looking into getting the 6′ bar.

    • jburgeson May 24, 2018, 10:13 pm

      Just so you don’t have to bend over to pick it up I suppose. It’s easier to load too, but I mean we’re talking bicep curls not deadlifts. How much weight could possibly be on the bar! haha

      I don’t think I know a soul who owns a rackable curl bar.

  • Kristopher September 24, 2018, 7:34 am

    Great review! I’m currently putting together my home gym and Vulcan allows this bar to be added at $132.99 when purchased with bumpers and a barbell. Thank you for the help.

    • jburgeson September 24, 2018, 9:52 am

      Of course! Thank you!

  • Steve November 25, 2019, 8:34 pm

    I recently picked up one of these. Vulcan customer service was ok, but the owner of the company is a nasty SOB. That said, the bar looks great and despite some really awful packaging (no padding of any kind), it arrived with no visible damage. However, it doesn’t spin at all. Really. No spin. If that’s an issue for you, move along. As an aside, it is made in China, not the US as this review claims.

    • jburgeson November 26, 2019, 11:25 am

      I actually have it mentioned a couple times in the review that it’s not made in the USA, I don’t know how in the world I had that it was USA-made in the opening specs, but I have removed it. My apologies

  • Milan July 20, 2020, 7:03 pm

    Great detailed review, made me want to buy Vulcan over Rogue. Been trying to buy it for last 4 months. The problem is it’s been out of stock and they won’t tell if or when they’ll have it. I missed it twice in April and it hasn’t been seen since. Well, their website hasn’t been updating much, kind of like feel of closing down, everything out of stock. Don’t know. Not easy to buy anything nowadays due to COVID-19.
    Thanks again

    • jburgeson July 21, 2020, 8:36 am

      I don’t think Vulcan is going anywhere. I don’t know why it’s taken four months to restock that particular item, but I’m pretty sure they’ll be around for the foreseeable future. It does suck though – it’s a great curl bar.

  • Mike V February 27, 2021, 8:13 am

    Another great article!

    I live in Bentonville Arkansas so it can get pretty humid down here but my gym is in my garage (not outside). How big of an issue do you think rust will be for black oxide and also raw steel finish? And how often would you recommend I oil it? I am not against maintenance but I’m trying understand the commitment I would need to give the bar the right attention it needs. Thanks.

    • Mike V February 27, 2021, 12:36 pm

      Apparently they have been out of stock for sometime now and it doesn’t sound like they are going to be getting back instock anytime soon. Do you have any reviews Archon or Rep ez bar?

    • jburgeson March 1, 2021, 12:07 pm

      Your bars will definitely oxidized; especially where you’re touching them. I would say a weekly oiling would suffice.

      You’ll get a feel for how quickly it happens and how often you need to clean and oil in no time at all. It becomes a quicker thing to do because the sleeves and 70% of the shaft never get touched, so you’ll need to oil there less frequently. It only really becomes a headache when you outright neglect the bar and you let the rust get out of hand. Bare steel can be restored mostly with steel wire brushes, but oxide can’t really be hit with a wire brush without taking off more finish.
