Good freewheel and chain, my Dad's Gitane freewheel and chain exhibited little to no wear and is now 37 years old. Any of the Shimano machines I have here are all pooched, bent and chipped teeth and rounded chainrings.
The only reason I went with SRAM is that they bought up Sachs ;). We'll see how that goes.
