Questions & Answers

Ask a Question
  • Does this barbell come with the replacement chrome end caps?

    All barbell orders now ship with stamped metal endcaps

  • is this bar available to purchase in the uk?

    We do and have shipped our New Gen Power Power Bar to the UK, UPS must be selected due to USPS not being able to ship this item due to it's length.

  • Greetings, I just a had a quick question about the electroless nickel coating. How is this compared to just zinc? I have not seen this offered before. Thank you for your time.

    The electroless nickel coating is a very high end coating often used in engineering parts. Most plating shops don't have tanks big enough to accomodate a barbell so not a lot of companies offer it. It will have a very similar high level of corossion resistance like the zinc, but it will keep it's shine a lot longer and is a harder finish.

  • Wanted to know the difference between the zinc, black oxide and nickel options?

    The biggest differences are going to be in color and corossion resistance. The black oxide is black, making that unique, but it is also the least corrosion resistant. It only has a mild corrosion resistance and is better suited for climate controlled environments. 

    The zinc and nickel are pretty equally corrosion resistant, but look fairly different. There are pictures of the two finishes for both the Duffalo bar and the Shoulderok. The zinc has a more blue-ish silver look to it, where the nickel has a shinier bronze look to it. The nickel is also significantly harder and more durable than the zinc finish as well. 

  • For the nickel option, is the sleeve chrome or also nickel?

    It is also nickel.

  • Hi, will these bars be available unplated at any point? Thanks, Chad

    We are not offering an unplated version of the bar.  

  • Hi, what finish would you suggest that will look the best over time? I've had zinc from another company in the past and it wore badly in the grip areas. I have an air conditioned space, so normally I go with bare steel, but since that is not available, would black oxide retain it's finish well with maintenance? I plan on keeping this bar forever, so would like it to look decent when I pass it on to my sons. Ha. Also, do the different finishes change the knurl feel at all? Thanks!

    You honestly could not go wrong with any of our finishes.  They will age well and the knurl will not wear down.  As for the knurl feel, there is little noticeable difference between the different finishes.

  • Describe the feel of the knurling between the 3 coatings

    There is honestly no noticeable difference between the knurling in the three coatings.

  • Hello, I've seen the video where your bar "eats" the competitors knurling, but I wanted to know which coating was on your bar for that test. Was it the bare, uncoated bar? The reason I ask is that it seems likely the zinc coating will rub off well before the extremely hard knurling wears down. How will that affect the longevity of the bar? Once the zinc is gone and the metal begins to rust, will the knurling still be virtually indestructible?

    Barring any metal on metal impacts, the zinc finish shouldn't rub off at all, but the test was done using an electroless nickel coated bar and even that didn't eat into the finish - however that is a harder finish than the zinc. Even if the bar was stripped of it's finish, it isn't going to affect the hardness at all and even with a patina the knurling will still last just as long.

  • how does this bar compare to the Eileko power bar , rogue power bar or the titex bar?

    This bar will respond similarly to the aforementioned bars, but it has a much higher rockwell hardness/tensile strength so the knurling is going to last much longer. We also have a different type of knurl compared to these bars that creates more surface area than a standard bar which improves grip.

  • For anyone who has this bar or experience with it during deadlift dose it have a ton of whip or minimal?

    Hey Enrique,

    This bar has very minimal whip and is comparable to other 29mm power bars

  • if I buy a next gen power bar, can I get the upgraded chromed end caps as seen in Brandon Campbell fitness video?

    Yes all Power and Squat Bars will have new end caps on them.
