Hello sr_roboto, welcome to the forums. are you in the US?
the red bike looks like a '84 Special, but with barends and maybe a different crank. what are the parts?
this one because it was purchased in Germany.. by you or the previous owner? is a bit tougher. the Pearlescent White paint and red 'flag' decals really make it look alot like a '87 Campione De Italia, the shape of the Ofmega (?) HS, the Ofmega (?) cranks and Ambrosio rims really make it look like that one too. what are the derailleurs? Ofmega Mistral? the US catalog list this as coming with Suntour Cyclone 7000 derailleurs but, as I have learned since coming here, it seems there were some shipped with the Mistral too.
more? better pics?
