The lateral wobble is very small and I wouldn't think it could cause vertical shaking of the chain. How can I change it when the sprocket is pressed up against bare spokes (no other way to do it on this bike)?
The chain is quite tight. About a half inch of slack.
I think my question is, how much shaking of the chain is to be expected when everything is properly installed? I'm just lifting the wheel up off the pavement and allowing the wheel to turn at about 10 mph.
Don't use the center hole as a guide for centering the sprocket!!! Spin the wheel & use the tips of teeth for centering!!!
