Front derailers

Evaluating

These are the parts a front derailer has that can be lost. On the left is the screw that holds the cage together. The two similar screws limit the derailer's travel, and the one next to them holds the cable. The screw at the top holds the derailer to the frame.

Front derailers need to have all of their parts. Sometimes they break, but more often one or more small parts are missing. If the derailer has all of its parts, it's OK.

 Front derailers need to have all of their parts. Sometimes they break, but more often one or more small parts are missing.  If the derailer has all of its parts, it's OK.
