My mom has and likes a Trek R200. She bought one new and a second lightly used one a few years ago when it showed up cheap at the bike store.
The second one is starting to wear down its front cassette (the bike is a weird one with a front rear derailleur and a front cassette and a rear rear derailleur and a rear cassette). Is it possible to find or make a replacement for this part?
This is the component in question:
