I
still can't get used to the idea of hydraulic shocks on a
vintage bicycle. 
But then I came across this little gem:
"...we all know that any mountain bike is not possible without suspension travel as it acts as a shock absorber on uneven trails or descents. So, Brian Skinner was the first to introduce a mountain bike with a suspension in 1982."
- from "The History of Mountain Biking, From 1930 to Date"
Forty years ago? That's vintage in anybody's book.
