I’m guessing I just bought a non-Homegrown Schwinn with a Homegrown sticker on it, but I found your site and thought I’d ask to see if anyone knows.
It has internal cable routing for the rear brake and downtube cable routing for the front and rear derailleur. The welds look like they’ve been cleaned up a little and it has a black to dark purple fade that shows up in the sun. It has a 1″ headtube. I haven’t seen any other Homegrowns like this.
