1987 Raleigh Randonner with long cage Sachs-Huret rear derailleur
more pics here and another chap's RR here.
Sachs-Huret are now Sram.
1981 looks like the date for this one, more pics of the same bike here
can't find out the model name though: Criterium? Olympic?
Super Vitus 971 tubing is apparently butted, high-strength low alloy medium carbon steel
either XC35 or XC38, 0.9mm to 0.6mm wall thickness, or so I am told
there was something else I was going to look for as well but I can't think what it was...
