I am the original owner and I bought this 753 new as a backup bike. It has only been ridden about 5 miles and that has been just to keep it maintained.
It has been freshened up 2 years ago with new rubber all around including brakes and re true wheels. Its unique combination of components (Campy, shimano etc.) all original and top of the line to when it was built. Considering selling and wondering what a fair price would be. Feel free to request pics. Bike is immaculate. .
