OK, forgive my ignorance, but I am confused. I have a Coerce ultra low bar, and as such, am not running the stock bar end weights. The bar itself isn't threaded on the end. How would a bar end weight connect to the inside of it with this in mind?
Either a rubber tube that fits over a bolt – the tube and bolt are pushed into the bar and when the bolt is tightened from the outside the nut is forced into the rubber making it fatter, thus a tight fit within the hole. See attached image.
Some have alloy sleeve that is slotted and expands over the nut when it is tightened.
You will need to check the internal diameter of the bar – steel bars have a larger hole than alloy so there are two sizes.
most that I have seen have a compressible rubber piece that gets fatter and holds itself in the bar as the screw is tightened. Hard to explain in text, but I'm sure there is a photo out there somewhere.
I for a couple years now..... have made my own inserts.
An Ace hardware or Lowes usually has the parts......
You take a long bolt that fits through your weight and into the bar (The farther the bolt goes in the bar....the better)......then put a plastic spacer on the thread (the longer the bolt, the more plastic spacers you'll need)....and at the end, screw on a expanion nut.....the longer the expansion nut, the better.....the one shown is pretty short, but you get the idea. (sometimes, you have to cut the lip of the nut off with a utility knife) Shove it in there....and screw it down. works perfect.
