22-32-42 on the chainring and 13-15-17-19-21-24-34 for the rear cluster makes for very low gear ratios indeed. I shall have to do something about that to make this bike decently ridable. I'd like to see if I can go 32-42-52 for the chainrings, but I'll need to do some research to find out what kind of components are available.
One thing's for sure: this isn't going to be cheap. Bike components haven't gotten any less expensive since my road days.
You know what I need? A bike repair/maintenance/customization/overhaul collective... I do some of my own work, but I have lots to learn. Park Tool has a traveling school, but they aren't scheduled to come anywhere near Charleston that I can see. I would really like to learn more about the technical side of keeping a bike up, and I bet a lot of people are in my basic situation.
Sounds like a great idea to get a bunch of cyclists together for a basic/routine maintenance workshop. I don't know if any of the cycling groups in the area already do something like that but it strikes me as a cool thing to do.
