The newer version has different dip handles, theyre adjustable where as the old one are fixed width and there are different measurements for the attachments. They are being made by a new manufacturer the steel is slightly higher quality but same thickness al around. I wouldnt worry about the steel though as the old style is more than capable of holding weight most trainees would be using and if youre using weight it cant handle then you probably wouldnt be looking at this type of rack.
