i originally welded the cassette on my conversion, but i made the mistake of riding it with no brakes so the only thing that held the cassette to my hub was 30 years of rust and old age, eventually i hit a rather large pothole while skipping and completely destroyed the rear wheel....

then i upgraded..



thats a durace cog and a bottom bracket lockring threaded onto a road freewheel hub on my old conversion, i used large amounts of red locktite because i don't have brakes..but i would greatly reccomend using brakes if you are going to suicide hub it.
