Re: A not perfect rag
Properly installed the rag joint will work and give you no problems. In your case you have a defective part. Order new parts, they're available from most of the advertising vendors you see down the sides of the page.
The sprocket-rubber-spoke rubber sandwich, so called 'rag joint' gets a lot of bad press here. Bent or broken spokes, out of alignment, wobbling, on and on. The fact is that, as I said above, installed properly using a sprocket that is not warped and making sure the rubber parts are of consistant thickness, properly torqued bolts and correctly centered on the hub, there is no reason that the kit sprocket attachment parts will cause you problems.
You could sand or grind your rubber spacers so they are the same thickness across their surface. I'd just order new ones.
