i didn't read anything but the OP post. my opin on the adapter is, get a 6 bolt hub and 6 bolt sprocket. saves so much time and effort. makes chain alignment easy as pie. doesn't wear out the spokes. i've tried all the adapters and found the hub to the the cheapest, easiest solution. for $50 bucks i built a heavy duty rim the with 6 bolt hub. never have to worry about the hub or rag joint slipping at all. second to the hub is the rag joint. i've put thousands of miles on them with out a single failure. it's just they are ugly and time consuming to set up. hub with 6 bolts is just slap and go.
