Has anyone made their own beadlocks like the secondair ones. It seems like they are way over priced. the Idea is good but they should sell for more like 50-100 apiece. They look like they would be easy to duplicat for much less than they charge for them. It looks like all you need is a canvas "belt" and correct size innertube maybe some glue to hold them together? and a piece of brake line or something of the sort to port your valve to fill the tire arround the bladder of the tube. I am going to experiment with this on one of my older rims when I get the time and would like to know if anyone else has made their own. thanks in advance
