I appreciate all of the suggestions but I never could do anything 1/2 AS#. If something doesn't work the way it's suppose to, I have to make it work the way it's suppose to. My only problem is I don't know how to select a generic or brand name replacement front derailleur if it's not OEM. The original front derailleur is a Shimano Top Swing 515. I guess it must be exclusive to the Wal-Mart Schwinn Aluminum Comp.
Don't have a LBS.
