The one on the left is a newly restored 83 Fuji S12 S. I changed out the cassette for a Shimano SIS 7 spd and it shifts much smoother than the old cassette. It got a set of bull horn handlebars for city riding, Brooks saddle, new tires, clipless pedals, new paint and it had all good high end alloy components otherwise. I use it as a daily commuter to work when the weather is nice and dry. I found it at the scrap yard for free. It had an ugly silver color and factory graphics and a lot of scratches. It rides beautifully and takes second place only to my plush handbuilt FC cycles that I spent so much time and money on.
The one on the right is an original condition 77 Raleigh Grand Prix 10 spd that I have had for years but do not ride. I don't like the gearing and the frame geometry is not comfortable. I have not done any work on it as all is in good shape.
