Sheldon Brown has a
page that tries to explain the difference between a bushed and unbushed chain (i.e. bushingless).
The bushed chain has a sleeve that the roller rides on, while the bushingless chain has a small flange on the interior of each side plate that supports the roller. I think that the point of this is that this allows the chain to flex laterally more. Sheldon has a
page that shows the small flanges on the side plates.
As far as noise... it might indeed be the chain smacking the cage..
Maybe the derailleur hangar is misaligned, or some other problem with the set-up?
