Well apparently I need a new crankset (2000 Schwinn Moab) so I am looking for a new setup or a replacment. Can I replace the rings as I obviously cannot fix them, especially since one has a broken tooth..? If I need to replace the whole thing I would like to be as close to the stock part as possible but improvements are always welcome! This bike is primarily used as a commuter but might see an occasional light trail.

THANKS!

John
