Default Re: hub adapter vs spoke clamp

I just took apart my first ever build and found that the rubber on the rag joint had worn thin and unevenly

Theoretically the rubber pinches together and does not allow for any movement against the spokes

What we found was that it was in fact moving back and forth and the the rubber had worn in different places , causing the sprocket to become uneven, causing the chain to pop off frequently

This is a bike that has seen some extreme use over a year, sometimes being asked to carry upwards of 400 pounds Now we are scrapping that bike (for that person) and building a purpose built truck bike but haven't decided on a sprocket adapter or a jack shaft.
But we know for sure that the rag joint will definitely be discarded
