Plating: Zinc

The 250k Power Bar ships in: 1-2 Weeks

  • PRICE DROP: We've reduced the price of our 250k New Gen Power Bar by over $200 off thanks to improvements in our operational and manufacturing capabilities!

When we introduced the 250k Power Bar five years ago, it took the strength world by storm as the industry’s hardest, most durable, and most refined straight barbell design. In the spirit of innovation, we took the same design engineering and analytic development principles that were cornerstones in the design of our specialty bars and applied them to a long-unchanged and stagnant design of a standard olympic straight bar to make it better and higher performing than anything on the market to this day. In one customer’s own words, this bar is“functional/industrial art…an object lesson in craftsmanship and precision”

Featuring an unmatched tensile strength and hardness of 250k PSI and 51 rockwell respectively,  the 250k Power Bar achieves these incredible numbers through a proprietary metallurgical heat treat process that results in a long lasting bar you can hand down for generations. Our unique knurl design is lauded as one of the “stickiest” bar-to-human interfaces without cutting the lifter's hands. The “Kabuki Feel” as, as it’s commonly referred to, is the result of a unique combination of innovations in material selection, proprietary manufacturing processes, and our comprehensive practical and theoretical experience in barbell design.


The 250k Power Bar

What is it about our new generation bars that sets them apart? A comprehensive testing and methodology was used throughout the entire product development process for our new generation bars. Materials selection involved testing to determine the optimal steel alloy to use. Lots of testing was performed on the hardening process and figuring out a way to create the hardest bar while still allowing for whip and preventing the bar from snapping. The knurl took us many many revisions to figure out until we all agreed on the production version of the knurl – widely considered to be the best knurl in the industry. Overall this bar has been tested and retested many times with every feature and specification in mind.

With a tensile strength of over 250k PSI and a Rockwell hardness of 51 RC, this bar is harder than any other bar currently 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. 

During the design engineering phase, we put a lot of resources and time into the knurl on this barbell. 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 contact points per square inch and creating more surface area in which to create friction.

The attention to detail, material selection, construction quality, and performance of this bar place it in a class of its own, something we can say about all Kabuki barbells and products. We are passionate about doing things right, putting our customers first, and taking the time to craft something beautiful that we can all be proud of. Bars come with our beloved and unique stamped end-cap design that features the Kabuki Squat Face iconography as well as the weight of the bar and its country of origin (USA).

We manufacture our New Generation bars using American steel by state-of-the-art machines, and hand-assembled in Portland, Oregon by passionate machinists and technicians. We design and manufacture these bars to function for life - bars you can proudly hand down to your children, and them to their children - making the world a better place through strength, generation after generation.

Frequently Asked Questions

A bar’s metallurgical properties are the primary determining factors in the mechanical properties of the bar, or in more practical terms, how the bar behaves in the lifter hands against gravity and the force generated. The yield strength of the metal determines how much stress it can take before permanent deformation, while the tensile strength measures its breaking, or fracture point. The softer, or lower strength a bar is - the more it bends under load. The harder, or higher yield/tensile strength a bar is - the less it bends under load. Each of these options varies the feel or oscillation of a bar under load, and the art of bar design comes in determining the fine dance between the bars properties and how it behaves under load, against gravity. One downside of higher tensile strength is brittleness, or catastrophic failure (not bending, but cracking under tension).

Our knurl was designed from the ground up and based on established research to 1) be the “stickiest” knurl possible, 2) minimize dermal penetration and damage to skin, and 3) maximize neural response.

Besides the unmatched knurl design, Kabuki’s new generation straight 250k barbells use a proprietary metallurgical technique to produce a hardness that preserves the durability of higher tensile strength & rockwell hardness while mitigating the traditionally-associated fracture risk + negative oscillation and physics properties. Years of practical experience in strength sports, deeper continuing education in exercise science and kinesiology, combined with a technical background in engineering/metallurgy makes Kabuki the perfect team to fine-tune the perfect barbell using novel techniques.

The 250k Power Bar comes in 2 standard metallic finishes and different seasonal cerakote finishes. 

Black Oxide:This low-cost option is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimize light reflection. We particularly like the gunmetal black finish it gives to the bar. It just looks badass in our opinion!

Zinc:The least expensive plating option, zinc is shiny and bright on arrival with a hue that varies from bluish to brownish. As the bar is used this coating will develop a dull, gunmetal grey patina. This default option is a very durable and corrosion-resistant plating choice commonly found on many barbells.

Cerakote: Cerakote is a ceramic based coating, originally used in the firearms industry for its excellent corrosion resistance and wear characteristics without excessive coating buildup. Cerakote is known for being a highly protective finish that stands up to the elements well. When cleaning chalk from the knurl on a cerakote bar, be sure to use a stiff nylon bristle brush, not a wire-bristled brush. 

Yes, the 250k Power Bar meets the competition specifications for the IPF, USAPL, IPL, and USPA along with all other major powerlifting federations. Only metallic finishes like Zinc or Black Oxide can be used on the competition platform.

Unlike any other bar I have owned. Pretty much perfect grip.

Received a blemished barbell with no center knurl ring and marks on one sleeve

I received the black oxide barbell that did not have a ring on the center knurl as shown on the website. The barbell also has several water type marks on the one sleeve that made it seem like it should have been sold as a blemish bar.

To make matters worse, I have reached out to their customer service and it has gone on to at least 2 business days to hear anything back.

I am currently stuck with a $600 barbell that didn’t show up like advertised and appears to be a blemished bar.

If you are ever able to read this, I would highly suggest looking to another company to buy a high end barbell

By far my favorite

I’ve had this bar on my wish list for several years now. I kept waiting for the electroless nickel bar to come back on the market (I discovered this almost immediately after it was discontinued) but in the absence of that, my wife bought me the black oxide with nickel sleeves bar.

I couldn’t be happier with it. I have been using a pretty decent bar from a big name company up until this point and been quite happy with it. However, I could tell the instant I grabbed this from the box that this bar was different. If you are at a point in your lifts where grip strength matters (rows, deadlifts, that sort of thing) but want a single bar to cover all your needs, do yourself a huge favor and start with this bar. None of the pain you’d expect from sharp knurling, but this thing couldn’t slip out of my hands if I tried.

That said, I use it on all my lifts. It just feels amazing.

As a plus, the packaging is almost as hard as the bar itself. I shipped to Copenhagen in Denmark, and it arrived in flawless condition. Kudos to Kabuki for that!

good motor, bad body

seems to perform well, knurling kabuki special. HOWEVER, seems thin, like a 28.5mm, BUT the biggest issue is the black oxide is ugly, very blotchy and DULL. definitely not the quality i’d expect from kabuki. very disappointing

Phenomenal Bar

Coming from a 28mm Olympic training bar with a lot of whip, I was immediately in love once I pulled this black oxide bar out with the knurl and extra mm in diameter. The knurl is literally perfect for me. It’s aggressive but not sharp so there’s not going to be issues working with it daily. Can’t really say much more other than if you invest in this power bar, it’ll pay itself off with plenty of longevity and work in the long run. Easily worth the extra cost over other power bars I was looking at for me. Next up is hopefully a Kadillac bar
