Hello zack, what do you mean the derailleurs are beyond repair? are they bent? are they rusted in two?
I think before you do anything you may regrett you ned to post some pics. I know Menomonee Falls, WI is pretty flat but one day you may end up down by Prairie Do Chicken and wish you had some different gears.
