I need to replace the front derailleur on my friends bike, this one is old and rusted, its a shimano FD M191. I've read a bit about what I need to know before I buy a new one but I just wanted to be sure before I make the plunge. Please excuse my newbiness...
The current one has a down pulling cable fix and serves 3 cogs, from what I gather these are the only factors that I have to ensure my new derailleur caters for. Is this correct? Can anyone recommend me something sub $30 that would work, and is there anything else I need to consider?
Thanks.
