This is why you should buy a quality barbell from the start. This bar is a standard thickness bar (28mm) from memory. It lasted to 130kg dead lifts then bent like a banana. So for those looking into getting started dont waste your money on a cheap barbell. As you will not only have to replace your barbell but also all of your weight plates will have to be converted over to the Olympic size as I have not found a standard thickness bar that is rated very high. Also the knurling on cheap bars is very crappy and they have no bearings in them. So save yourself some money for the future and get a decent Olympic size bar to begin with. I went with the ABC Power Bar and it feels incredible. I know theres still a lot better (dearer) out there but this will suit me fine for a veeeeeery long time
