Re: Cranbrook, Chain shake/flap/slap
"Everything seems to be in line. There is very little wobble of the sprocket and it seems well centered."
That sprocket needs to be centered PERFECTLY and parallel to the wheel. Its been my experience that one half inch of play up or down is all the play that is necessary on a chain. This doesnt apply to chains with spring loaded tensioners such as derailleurs. If your chain sprocket is off center by just 1/16th of an inch then the wobble will be an 1/8th when doubled by being round. The importance of having the chain parallel is to reduce wear on the sprocket and chain and to keep the chain from guiding off of the sprocket.
