IMPORTANT: For cerakote-coated barbells, added care should be used to avoid abrasive metal-to-metal contact. Tight-fitting collars, weight plates, un-lined landmine attachments and j-cups, etc — these can potentially cut into or wear off the cerakote finish. Taking these extra precautions will preserve that beautiful rust-resistant finish for years to come!

Great Bar!!!!

Aggressive knurling. Does seem to scratch easily. Would recommend!


Bells of Steel

Thanks for the 5 Star Review! Great to hear you are enjoying your new powerlifting bar! Unfortunately scratching easily is just a downside of cerakote but it does make the bar look great. Happy lifting! Brandon and the B.o.S. Team

Amazing Bar and Customer Service

This is currently my favorite barbell for powerlifting. When it comes to cerakote I've noticed that on a lot of other companies it dulls the knurling. Between having a second hand Barenaked BOS bar and this cerakote version there was no difference. The knurling is fantastic and the cerakote doesn't dull it at all. The bar is also stiff like a powerlifting bar should be and has very little give even when getting up to 5 plates. The only cons I ran into were rust already on the bar which I was able to clean and the cerakote chipping on the shaft where it doesn't even touch the rack. These cons only gave their amazing customer service a time to shine though as they were able to address the issue quickly and offered a replacement or store credit after a few pictures.


Bells of Steel

Hey Tyler, Thank you for the review and the feedback! We are happy you are enjoying both bars and have found the knurling fantastic as well as our CS team was able to help you out! Enjoy all the gainz! Yours in strength, William & the BoS crew

The coating where you put the weights comes off very quickly


Bells of Steel

Hey Spencer, Thank you for the review and feedback, with any bar coating it helps to reduce the rust but isn't abrasion resistant so chipping can happen on the sleeves. Enjoy the gainz! Yours in strength, William & the BoS crew

Good knurling, not cerakote

Bar is functional however the “cerakote” finish scrapped off when I loaded the very first plate. Also the bearings won’t free spin a single rotation when spun by hand.


Bells of Steel

Thank you for your feedback, Scott. Unfortunately, a common problem with cerakote is that it can easily be stripped off by steel-on-steel contact. As for the bushings not spinning very well, because this is a powerlifting bar, they are not designed to spin as fast or smoothly as an Olympic lifting bar. I will reach out to you by email as well and we would be happy to exchange your bar for a new one or give you a refund if needed. I apologize that this product did not live up to your expectations.

Great feel but disappointing condition

I ordered an onyx cerakote power bar a few months ago I didn’t take it out of the tube until last month it came out of the tube rusted and with the cerakote chipping. I love the feel of the bar and knurling but considering I first had shipping issues with it and then the first time I used it the condition was poor after being stored in a climate controlled setting is extremely disappointing


Bells of Steel

Thanks for your review and your feedback Tyler. I am sorry to hear that you are having these issues with your cerakote barbell. We would be happy to give you a partial refund or exchange your bar for a new one without these issues. I will reach out to you by email as well. Yours in strength, Brandon
