Turns out the KombiLux has a Sachs Duomatic hub. Making lowball offer today.
Ethics question: If I know what it is and recognize value, but seller does not, should I feel bad with lowball offer?
This would be a bike I keep, not one I flip, although it could easily turn up on CL in the next couple of years, after riding it for a while, probably sporadically. Yes, I would expect to make more money on it that I would actually offer...
