Hey all so I've posted here 3-4 times regarding the problems I keep having with wheels. I'm on my 4th rear wheel and 2nd hub adapter. First 3 times with with my original 1' adapter it kept moving and snapping spokes. I filed it down to let there be a gap and it still ended up moving even after I got it very tight. I also measured the hubs with a caliper of the past 4 wheels and they have all been 1'. So this last wheel I had I used a new adapter and a 40t sprocket rather then my old 41t. I filed this one down to so it was sung, I also used friction tape as a shim since the past 3 rims failed when it was just metal on metal with lots of force. I even used a 3 foot breaker bar on the adapter to tighten the bolt as tight as they could ever be. I went for a ride tonight and it look like it slightly moved backwards and it pulled out 2 spokes. I don't understand what to do other then going back to a rag joint. I don't even know that heavy duty wheel with bigger spokes would hold up. I don't really want to use JB weld either.... I cant stress enough how tight I made that adapter! I went out and bought snap on Allen wrenches so I could get it super tight without stripping the cheap Allen wrenches. I cant be the only person with these bike with the problem happening over and over again. Really looking for help.
