this is a shot in the dark, but looking for a replacement hanger for my argenta 2001.
looked with CNC Machined Bicycle Parts, AE bikes, rearderailleur.com, and marin = all were NO GOs.
even went on craigslist to find the bike and tried calling the sellers to see if they had an extra hanger laying around.
can you help out? if i can't find it, gonna have to scrap the frame
here's a pic:
