It's pretty amazing how well a lot of the 1980s (or a lot earlier) stuff still works if it's maintained reasnonably well rather than abused. I have a bicycle with the old Shimano 600 EX stuff on it including the scallop headset and I never have problems with it. I even have a number of NOS Uniglidge cassettes for it. I also have another bicycle with Duara Ace AX on itthat's still going strong. I just adore the stopping power of those brakes. Plus those brakes are the absolute easiest brakes to center if they should ever get knocked off center = just hold the center section of the brake caliper and move it to the centered position = no fuss no bother. My bicycle with the New 600 groupset still shifts flawlessly to. I think thatthe old stuff had a lot less that could go wrong with it in the shifting department.

Cheers
