6/7/2019 - After using the Kabuki New Gen Power Bar for nearly two years now (and doing so rather consistently) we are confident in our initial findings that this is one of the best power bars currently available. If you don't mind the price, this is likely your best bet.

The Kabuki Strength New Generation Power Bar is the best power bar we've tested to date. Everything from the knurling to the tensile strength of the steel is superior to other power bars we've reviewed including our previous favorite, the Rogue Ohio Power Bar. If you're looking for the best bar for powerlifting specific training and are willing to spend money to get it, this is the bar we recommend.

Kabuki Strength New Generation Power Bar
(7 ratings & reviews)
This bar is our IPF spec, multi purpose, power bar. It I a 29mm bar, with aggressive but not overly sharp knurl, and standard powerlifting markings.  What is it about our new generation bars that sets them apart? With a tensile strength of over 250k PSI and a rockwell hardness of 51 RC, this bar is harder than any other currently bar on market. What this means in practical terms is that the knurl won’t wear down over the years, leaving you with a bar that is performing sub par compared to when it was new. Even where the bar contacts the rack it will maintain that fine, tacky, aggressive knurl just like the day it was unboxed.  The knurl itself is the other piece of engineering that went into this bar this bar that we are proud of. We wanted to create something that grabbed well but wasn’t so unnecessarily sharp that it cut your hands rather than grabbing. The knurl of our bar is finer than most barbells you will find, giving the knurl more points per square inch and creating more surface area  to create friction against.  Lastly, another small feature to differentiate our bar is the center marks in the knurl. We wanted to leave the power bar with a continuous center knurl so as to not lose any of the grip effects for squatting, but still have marking to indicate the bars center for alignment purposes. We fully stand behind our product and believe in it wholeheartedly, which is why each bar comes with a 5 year warranty against any type of manufacturing defect. What this means is if your bar begins to wear prematurely, we will repair or replace it free of charge.  While our bar does have a higher tensile strength – what this doesn’t mean is that we will warranty against customer induced damage such as dropping the bar into metal safety pins. Depending on many variables such as the height and weight used this is just simply too much force into one area of the bar to not cause permanent deformation.

Details That Go Into Producing World-Class Barbells

Tensile strength is something that gets thrown around the industry quite a bit, and I want to clarify a couple of things.

First off, there is no such thing as a 1,000 lb, 1,500 lb, or 2,000 lb rated barbell. It's a fantastical myth created by cheap barbell manufacturers trying to appeal to the simple consumer. In fact, I'd go as far as to say that you should avoid any company trying to market to you in this manner.

The main things that count in judging steel in the barbell industry have been tensile strength and yield strength. There's also another measurement that has been brought to light by Chris Duffin and Kabuki Strength, and that is Rockwell Hardness which we'll get into in the review.

Tensile strength is simply the resistance of a material, in this case - steel, from breaking under tension. Yield strength refers to the force a barbell can endure before permanently bending or deviating from its original straightness.

Tensile strength matters because barbells do sometimes break, although more often they bend. In fact, due to bars bending more often than breaking, yield strength is likely a better measurement for judging barbells then tensile strength. But, tensile strength is still very important to see when purchasing a bar, especially one designed for powerlifting.

When purchasing a power bar, the tensile strength should be a substantial consideration due to the stress that will likely be put on the bar. Power bars should also be stiff, which is a difficult combination when trying to also have a very strong bar. Let me briefly explain:

Tensile strength tells us more about the strength of the bar which is the ability to resist cracking/breaking. This said, just because a barbell is strong, that does NOT mean the barbell is stiff. For example, an Eleiko (often held as the world's greatest Olympic Weightlifting barbell) has a high tensile strength and therefore is really strong, but it's not relatively stiff. Due to this, the barbell can both resist a high load without cracking, while also being able to deflect that load and go back to being straight. The stiffer a bar, the more likely it is to bend.

So, seeing as the Kabuki Strength Power Bar is both stiff AND strong, this makes it outstanding for powerlifting. This is done using a process that from my sources has not been adopted by the barbell industry until now. I plan on going into this further in a future article, but for the time being, this should suffice.

Kabuki Strength New Generation Power Bar Review

The Kabuki Strength New Generation Power Bar is the best power bar I've used, and I don't say that lightly. At Garage Gym Reviews we've had the opportunity to use and review some excellent barbells. These include the American Barbell Mammoth Bar (a Cerakoted, stainless steel behemoth) as well as the Stainless Steel Rogue Ohio Power Bar.

Are there other power bars worth mentioning when comparing the Kabuki Strength Power Bar? Of course, a few notable ones are the Eleiko Powerlifting Training & Competition Bars, the old Iron Wolfe Barbells that aren't currently being made as well as some of Ivanko's barbells. Ivanko, the previous title holder of the 'Strongest Barbell Made in the USA,' has recently been dethroned, and it was done by this bar.

The Kabuki Strength Power Bar is not only the 'Strongest Barbell Made in the USA,' in my research, but I have also been unable to find a barbell that uses steel with a higher "certified" tensile strength. I say certified because this isn't a number Kabuki Strength made up, this is literally something they've had tested and documented. I believe this is important because there are many companies claiming >200K PSI Tensile Strength barbell without ever showing the public the details on how this number was garnered. We simply trust the companies, and in my experience, trusting companies running razor-thin margins and trying to make it based on volume is an empty pursuit.

The co-founder of Kabuki Strength, Chris Duffin is probably one of the most interesting guys in the strength world. He comes from a broken childhood (as I write this review on Thanksgiving day I  remind myself of how thankful I am for the home I grew up in), has built himself into a respectable man who has both done great things in the engineering world (worked for Boeing among others) as well as the powerlifting world. Thankfully, he combined his love for engineering with his passion for powerlifting and has graced us with some of the best equipment currently available.

Two notable pieces are the Kabuki Strength Duffalo Bar (our favorite specialty bar) and the Kabuki Strength ShouldeRok. As many were, when Chris announced he was working on a power bar, I got pretty excited. But, although I was excited, I was a bit hesitant. I've used a lot of barbells and have had some in-depth conversations with the owners as well as product designers of the top equipment manufacturing companies in the world. What I often take away from the conversations is there is a whole lot more to creating a barbell than what most assume (even if you're picking specs for an imported bar.)

Sure, Duffin and his team have done some awesome things, but a barbell is something that everyone is doing, in all reality, many are doing exceptionally well. However, the hype only increased after Kabuki Strength teased this video of Chris discussing the ins and outs of metallurgy and its relationship to barbells.

The most important detail from the video that I believe makes the Kabuki Strength Power Bar stand out from the rest is the combination of a high tensile strength (250K-258K PSI) as well as a high Rockwell Hardness rating of 51 RC.

Tensile strength is something most people who have purchased barbells within the past decade have a vague idea on. However, this is the first time I've seen a company discuss Rockwell Hardness and this is the only barbell that has this listed. Does this mean other companies have a low Rockwell Harness rating? No, but I do hope it causes an urgency for other companies making quality barbells to state all of the details as a differentiator among lesser-quality bars.

The combination of a high tensile strength and very hard steel create a bar who's knurling, as demonstrated by Kabuki Strength, is practically indestructible. For a garage gym owner, this matters, but for a commercial gym owner or anyone with many different hands on a bar, this is paramountly important. How many times have you gone to a commercial gym, barbell club, or CrossFit box and found all of the barbells have a non-existent knurling? Nearly every gym I've been to has bars with hardly any knurl, and that's because they see a lot of use while also using mild steel.

Having a barbell that will not only be less likely to bend (the steel used is most often used in the manufacturing of structural parts for aircraft landing gears) but also less likely to have a knurl that wears to nothing is what makes the retail price of $600 not seem so bad.

The barbell with my (previously) favorite knurl as well as most others is the Rogue Ohio Power Bar. The reason it's such a popular knurl is that it's aggressive, yet not sharp to the point that it tears the skin. Rather than digging deep into the bar and leaving sharp points like many other bars such as the overrated Texas Power Bar, the OPB has had the tops of the knurl cut off, leaving four times as many points. This creates a 'volcano looking' knurl that increases surface area with the palm.

This same 'volcano looking' knurl is used on the Kabuki Strength Power Bar, but, in my opinion, done even better than on the Rogue OPB. On the OPB there are much fewer points than on the KS Power Bar, which is likely done to save cost (this is just a guess) for the expense of having to replace tooling for cutting the knurl (this is an expensive part of barbell manufacturing as new tooling has to be replaced often, many times with each barbell.) This means that the Kabuki Strength Power Bar has a very similar knurl to the Rogue OPB, but, an even more precise knurl that creates even more points and therefore more surface area with the palm.

To put it bluntly, the Kabuki Strength Power Bar has the best feeling knurl of any barbell we've ever tested.

It must be said that this is subjective, but if you'd like to compare your preferences of knurling to mine, my previous favorite knurling is the Rogue Ohio Power Bar (for Powerlifting) and the Eleiko WL Training Bar (for Olympic Weightlifting.) One thing that isn't subjective though is the fact that this knurling will be around (in a similar condition as when you first receive it) for long enough to pass down to your grandchildren.

Although I love the knurling, that doesn't mean it's absolutely perfect. Due to the preciseness of the knurl, there are areas near the Powerlifting Knurl Marks that are double tracked about 1/8". This is very picky and won't affect the use of the bar, but my goal isn't to make this bar or any review appear better than it is. We'd like to see this perfected over time as well as the center knurl marks become more defined and even, but these are small issues.

A few other details outside of the knurling and tensile strength of the bar: The shaft diameter is 29 mm. Initially, they had teased they were going to use 28.5 mm as the shaft diameter, but I'm happy they decided to listen to some of the comments regarding this. I prefer 29mm for the squat and press and don't mind it for deadlifting (although nothing feels as good as a slinky 27mm deadlift bar.)

There are various finishes that the bar is offered in, similar to their Duffalo Bar. Zinc and Black Oxide are offered and for an additional fee Electroless Nickel can be had (I love this finish, and it's rarely offered by other companies.) Another tease regarding the bar was to use stainless steel. Do I prefer stainless steel to a chrome or zinc finish? Of course, it's my favorite as shown in various reviews for its corrosion resistance. However, Kabuki Strength has said the reason they went with a plated finish instead of stainless steel was due to, and I quote Chris Duffin from an Instagram comment:

"Stainless is not inherently better and only provides corrosion resistant properties. But to accomplish that, it still requires a treatment such as passivation. If it requires treatment, we may as well go with a higher tensile strength steel that is better to work with and keeps costs lower. Then we do the electroless nickel finish which is arguably superior to stainless. In this manner, we improve function, cost, and finish."

This pretty much satisfies my inquiry and will likely to most of you reading this as well. If Stainless Steel was chosen and the same tensile strength was had, this bar would likely cost above $1,000 and therefore out of the price range for most. In my opinion, I'd rather see a bar at this price with the features it has than stainless steel.

The rotation system used is self-lubricating bronze bushings similar to many popular CrossFit-specific barbells. For a power bar, I think this is a great option that also keeps the price lower than if bearings were used. The New Generation Power Bar does have a mediocre spin, but would be enough for those that want to use it for some power cleans here and there.

Finally, this bar is manufactured in the USA while using American Steel. To some, this is a big deal, although it's not of utmost importance for me. The most significant part of this is not that it's made in the United States, but that American Steel is used. Many companies claim "Made in the USA" when although it's made here in the states, the steel is imported. This deceives customers into thinking everything about the bar is supporting American Workers.

In addition to the bar being made in the USA, it also carries a lifetime warranty. The best lifetime warranty in the industry in my experience is Rogue Fitness. Not only is their customer service second to none, but they generally take care of any and all inquiries. I certainly won't compare Kabuki Strength's lifetime warranty to Rogue's because they've neither been around as long or had as much experience servicing claims. BUT, I will say that the team at Kabuki is dedicated to making the best equipment possible and fixing situations when this isn't the case.

A lifetime warranty is great so long as the company is around long enough to service it. I'm hoping Kabuki will be as they're making some of the most attention to detail equipment in the industry.

I want to say one last thing regarding the price of this bar. Currently, the retail is $599. This is not cheap, and although the bar has features that can't be had at lower prices (or higher prices really), it's still a large purchase for many. A barbell is the area I suggest spending the most money when building a home gym. It will receive the most use, and there is a big difference between a $100 bar and a $200 bar. There's also a difference between a $400 and $600 bar, although the more you spend, the lesser the differences are.

The most prominent comparison this bar (or any power bar) will get is to the Rogue Ohio Power Bar which can be had for $250 and at that price it is an excellent value. For most people, I'd say the OPB is enough of a barbell. However, if you want one of the best power bars ever made, at a price that when compared to other comparable bars is MUCH less, then the Kabuki Strength Power Bar is worth every penny.

This should be the last barbell you ever buy that will not only provide a reliable, but enjoyable experience every time your calloused hands grip the outstanding, indestructible knurling. For those reasons, if I were going to buy a single power bar, this would be the one.

Suggested Improvements

Although I've given high praise to the Kabuki Strength New Generation Power Bar, it's not perfect. There hasn't been a review we've given yet in which there weren't things we could see improved.

First off, something we've previously mentioned is improving the knurling near the knurl marks. As said, for an 1/8" or so near the knurl marks, there is double tracked knurling. This shouldn't affect grip, but I believe this should be minimized as much as possible, especially at this price tag.

The second improvement I'd like to see is cosmetic, but both end caps on the bar came scratched up out of the tube. This is the ONE area a company can brand their bar so you may as well go all out and do something different, or at the very least make sure it's going to last. People want to show off a bar like this, but when the end cap gets banged up, it may be unidentifiable eventually. I've been saying this for years and still see underwhelming end cap designs.

*Update* I've been notified that new end caps have been created to prevent them from scratching and will be receiveing a replacement pair to compare.

The third improvement is on the spin. It doesn't need to spin like an Eleiko or Uesaka, but it should be smoother, in my opinion. I don't mean a longer spin, but one that comes to a slow halt rather than what felt like a sudden stop. This will eliminate as many factors as possible preventing someone from setting a world record. This said, the spin will likely improve overtime as it's used.

Finally, and this is also cosmetic, but one thing I really liked about the Duffalo Bar that I wish was done on the New Generation Bars was etching on the inside of the sleeve collars. This was a cool feature that may not be possible with a calibrated barbell, but I always liked the uniqueness.

2-Year Update

The Kabuki New Gen Power Bar, also know as the NGPB (it's pretty special when people start abbreviating your products names) is an expensive bar with quite a few claims in terms of durability. As such, I think it's pretty important to provide an update to our review and after using it for 2 years and hundreds of training sessions, I have some additional insights to provide.

First off, the hardness of the steel is every bit as true as has been marketed. I remember when the bar was initially teased, Chris Duffin took a NGPB and basically shaved down a Buddy Capps Texas Power Bar with it. I was impressed, but wasn't sure how that would translate to real world use. After using it for two years, I can say that the knurling is as sharp as it was on day one and the only thing that has worn down is the UHMW plastic on my j-cups.

I actually like the Kabuki Power Bar so much, I picked up another one in the same beautiful Electroless Nickel plating. One thing I noticed that's different on the new model versus the first one we reviewed is there is now no double tracked knurling and the bar is much shinier. Both of these things are improvements that I'm happy to see made.

I've squatted with this bar who knows how many times as well as other strength training movements like deadlifts and presses and it still feels like it did out of the box. This is not the case for even some of my higher end power bars like the Rogue Ohio Power Bar in the stainless steel variety as well as the Eleiko IPF Powerlifting Barbell.

Now, there are other power bars that have come out since we initially reviewed the Kabuki NGPB, such as the Rep Deep Knurl Stainless Steel Power Bar which we've reviewed, and although that's a killer bar with a very similar knurling, there's just something special about the Kabuki. Maybe it's knowing it will never wear out (although it could bend if not properly taken care of) or just knowing what went into making the bar, but it's definitely a barbell we recommend.

After two years of using and abusing the NGPB, I'm as much as a fan of the bar as I've ever been. Duffin and his team at Kabuki Strength have truly created a bar worthy of going down in strength history as one of the best ever made.
