I apologize if you discuss this all the time. I searched but didn't find the answer to the question I have.
I have a Giant Cadex 2 mountain bike. It's old. It came out in about 1992. It had Sun Tour components on it and they worked beautifully.
Then a few weeks ago something happened as I was pedalling and I managed to snap the part of the RD that hangs down (with the little wheel on it) in two.
I know next to nothing about mountain bike components. Does anyone have any suggestions for what level derailleur I ought to get to more or less match the old Sun Tour. This has become the bike I use to ride around town and run errands on. I don't want to call it a beater because it's carbon, and too nice for that, but i won't be riding it hard on trails and the like.
Thanks for your patience.
