I'm finally getting around to adding my Pro-Tour. I think it's a 79. Here are a few details and maybe someone off hand can indicate what year to be exact. I am sometimes tempted to sell it because it does not get rode a whole lot but when I do ride it I immediately change my mind about selling it. It rides so nice.

Completely chromed Champion #2 frame
Suntour Bar End shifters
Dia Compe brazed on center pulls
Kusuki Medallion 1000 stem (very sweet)
Kashimax saddle
SR Apex crank (triple)
Sunshine Pro-Am hubs
Suntour Cyclones
I have the original pedals and toe clips but I've mis-placed the original handle bars.
