Engineered by Champions

Designed and engineered by strength athlete and coach Chris Duffin and his design/engineering team.

Carefully Crafted

Designed and manufactured in-house at our world-famous facility – Kabuki Strength Lab

USPA and IPL Approved Bars

Both of our New Generation bars (Power and Squat Bar) are approved and certified for use in the USPA and IPL.

250k+ PSI Tensile Strength

Our proprietary manufacturing process allows us to make one of the hardest bars the industry has ever seen.

  • Are the Bars Certified/Approved for use in Powerlifting Federations?

    Yes! Both the Power Bar and Squat Bar are USPA and IPL approved for competition use. We are seeking out further approvals and certifications from other accreditation bodies, and both of our bars conform to international competition specs.

  • When are the bars available?

    They are available now!

  • How much do the Power Bar and Squat Bar cost?

    The retail price for the Power Bar is $599, and the Squat Bar is $699 for the Zinc finish.

  • What makes this bar different from others?

    Both of our new generation barbells, the power bar and squat bar, are made of a steel alloy that is hardened to over 250,000psi Tensile Strength using our proprietary process. As far as we know, this is the hardest bar on the market and nobody even comes close to offering a bar with these metallurgical specifications.

    Chris describes why “hardness” and “tensile strength” matter and what they mean in the video below titled “Metallurgy 101” so make sure to check that out!

    Our bars are also priced very competitively compared to higher-end bars.

  • Does the power bar meet the specs for a competition power bar?

    Yes, the power bar was designed with IPF/USAPL and IPL/USPA specifications in mind and fits within their required specs for a competition power bar.

  • What warranty do the bars come with?

    We guarantee our bar materials and workmanship for life and claims are handled on a case-by-case basis by our customer service team.

  • What is the difference between the Power Bar and the Squat Bar?

    See below for full specifications for each bar. The Power Bar is a 20 kilogram barbell commonly used in powerlifting meets as a 3-lift bar – for the squat, bench press, and deadlift.

    The Squat Bar is a specialty barbell that weighs 25 kilograms, is thicker and longer than a regular bar, and is used by many federations for the squat. Most big  (800+ pound) squats you’ve seen in competitions are done on a squat bar like ours.

Our Power Bar starts at $599 for the zinc version, while the Squat Bar is $699 for the same finish.


Testing occurred throughout the entire 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 – something we consider to be the best knurl in the industry. Overall this bar has been tested and retested hundreds of times with every feature and specification in mind.


In this video, our chief engineer and co-owner Chris Duffin discusses the metallurgy and science of barbells. He explains what the common numbers are data are used to describe barbells and what they mean practically in real-world performance. If you’re not convinced our bar is the best, this video will explain factually and objectively why it is.


This video shows a knurl test performed on our bar against a competitor’s power bar. The test had two components: 1) Our bar held stationary against a spinning competitors bar (on lathe) and 2) The competitor’s bar held stationary against our spinning bar.


The GOAT himself, Ed Coan stopped by the Kabuki Strength booth when we were down at the US Open in San Diego and had this to say about our new generation bars…


So what do all these numbers and figures below mean? Chris explains the metallurgy and science behind the bar in the video above in a very concise and easy-to-understand way. We’ve taken it upon ourselves to spend hundreds of hours researching, experimenting, and figuring out a way to create the ultimate barbell – a hard bar that performs well and will outlast its owner! Chris isn’t joking when he says in the video above that this is a bar you can pass down to your children.

Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, such as breaking or permanent deformation. Our bar has the highest certified tensile strength of any barbell on the market.
Rockwell Hardness
The Rockwell scale is a hardness scale based on indentation of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. In practical terms, the hardness will directly correlate to the longevity of the knurl.
Knurl Wear
Our bar withstood a knurl test for 300 seconds before we stopped the test. The knurl test involved using our barbell as the cutting tool against other barbells (and our own) spinning on a lathe. Other competitor bars lasted for 5 and 7 second respectively before their knurl completely failed.
Deformation @ 34,000N
In a deformation test using 34,000N force, our bar experienced 3x less deformation (.125 inches) than the average of both competitors bars.
