you need to find a derailleur that will fit the bike correctly.
i'm assuming the bike has a 46 or 48 large ring, correct?
I have learned a lot about derailleurs from the replies in this post, thanks!
This bike got a 48 ring as the largest , a 38 middle(?) ring and the smallest should be 28.
Will the FD in the link be working? Its a Shimano Altus FD M313 28" .
Manufacturer Part Number: EFDM313X6
