I posted this in the wrong spot earlier, I can't believe it's still for sale.
This is NOT one of my bikes, but I saw it on Craigslist, it appears to be in average condition for it's age, pitted aluminum that I saw can be cleaned up, can't see enough of the paint detail to determine condition. It was Centurions 2nd from the top of the line that year which offered Tange Champion 2 double butted 3 main tubes which brought the frame and fork weight to about 5 pounds. It also appears to have all the original Shimano 600 components, and it looks like the original Selle Italia Turbo Suede saddle! For only $75, at that price it may be worth a serious look, and be worth some elbow grease and whatever else it might need. It's located near Benton Harbor Michigan, which is too far for me to go see or I would have been there today! These are running about $250 to $350 in good condition.

If anyone decides to look at it let us know how it goes.
