Jamis Coda Comp
This bike is at least 16-18 years of age, maintained all those years but lived in fort myers during Ian. Was only in 4 inches of water for a day and in non conditioned air for 10 days. Did not ride after as roads were glass and debris. Moved and had bike serviced. Mechanic said derailer and shifter both were frozen and need replacing but parts are hard to find. He fixed as good as he could and as every mechanic I have ever had said, the bike is better than its replacement on the market today. (Assuming a bike of like type) . So, being illiterate on bikes, do I have to replace these component with exactly what I had or can I get new but different components. (I think it’s a 3/9 front with bottom pull and shifter, all shimano) I could be way taken advantage of as I don’t know what I’m looking for so any help on parts or a replacement bike is what I’m looking for.
