Huh??
Nice bike. Sounds like you totally scored. I brought up Argos a couple months back on another thread to see if anyone remembered them.
I do remember them. A knew 2 or 3 guys that had Argos bikes circa late 70s and early 80s. They must have had a distributor in norcal. They were nice pro level racing bikes and frankly a significant step up from an International in quality -- as much as I like those.
