Thanks, all. You did not disappoint.
The original narrow spaced bikes are (of course) built with the chainring(s) centered with the cogs on the rear hub. When you spread the frame for wider hubs, with more cogs to the right, doesn't this throw off the chainline, which is now no longer properly centered?
Or is this another measurement that most consider "close enough"? ...Just another part of doing this that I don't like.
