  • When do the bars become available?

    Bars are available for pre-order right now! Our timeline for delivery of pre-orders is below, and after this initial pre-order production run we expect to have regular inventory starting November 15.

    Take a look at the timeline below to understand how the pre-order process will work. If you get your pre-order in during the first few batches, you’ll be among the first to receive your bar when we start shipping November 1-15!

  • 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.

    Pre-orders of both bars are discounted 10% off the retail price, so the Power Bar is $540 and the Squat Bar is $630 during this pre-sale period. 

  • What makes this bar different from others?

    Both of our new generation barbells, the power bar and squat bar, are made of a aerospace-grade steel alloy that is hardened to over 51 Rockwell and 258,000psi 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!

    What this means in a nutshell, is that our new generation bars are the most durable, long-lasting, and high-quality barbells on the market right now. They are also priced very competitively compared to higher-end bars which are still fall under ours when comparing specifications.

  • Does the power bar meet the specifications 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.

Pre-Order your Power Bar or Squat Bar

Pre-order pricing is 10% off retail price. Estimated delivery based on timeline below.

HOW DOES THE PRE-SALE WORK?
HOW DOES THE PRE-SALE WORK?

The pre-order process for our new bars will be done “kickstarter” style. What this means, is that orders will be shipped out in the sequence they were received, and will be “batched” in sets of 50. The first batch will go out as soon as the first 50 production bars are complete, and subsequent batches will follow as they are produced.

If you want to be one of the first ones to receive your bar, make sure to get your pre-order in as quickly as possible! Remember that pre-sale pricing is discounted 10% off retail prices as a thank you for being a loyal and trusting customer of ours. Premium plating options are available as well at an additional cost, although the bar comes coated in Zinc by default.

Production and delivery will be based on the timeline above. We will keep customers informed of their order status based on the batch they are in and that batch’s current status in our manufacturing process. We will be fully transparent through this pre-sale process and hope to make it as comfortable and simple for our customers as possible.

If you have any questions or wish to check the status of your bar, simply email us at “info@kabukiwarrior.com” or fill out the contact form here with “Pre-Order” selected in the “What are you contacting us about?” field.

BAR TESTING

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.

METALLURGY 101 WITH CHRIS DUFFIN

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.

KNURL TEST

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.

ED COAN REVIEWS OUR BARS

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…

THE NUMBERS

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. Although we can’t disclose detail about our proprietary manufacturing process, we can say with certainty that we’ve produced the hardest, most durable bar the market has ever seen. Not only do the numbers back this up, but it’s performance in real-world and stress testing also demonstrates this. Nobody has ever brought a production bar this hard to market (258,000psi and 51 Rockwell) because doing so without risking catastrophic failure (bar snapping under load) is a difficult challenge. 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.

258kpsi
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.
51RC
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.
300s
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.
1/8thIN
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.
