Well there was quite a high spot on the sprocket and as it turned out it was right over that 3rd joint.
As it turns out the whole thing has to come apart any way because there is a clearance issue with chain and tire ( flat sprocket ) so I was thinking of putting an extra piece of rubber between the out side rag joint and the sprocket. Also think I will order a Manic Mechanic sprocket adaptor latter this week. Couple of pics to help explain.
Out of 30 or so sprocket upgrades I had six with that issue. They happened to be the ones that came with BGF $12 36t sprockets so maybe no surprise.
It only takes a minute to get plates seated by levering them apart with screwdriver. Once flat tighten nuts equally so edges don' t pop up. Not a problem for me at all. I had much more difficulty with clamshell mounts and coaster brake installs. I also believe the rag joint type absorb shock and extend spoke life more.
The first one took a few minutes longer but the rest went quickly now that I know.
BTW where did you get those? How much and what type?
