i was wondering what an appropriate chain for
a a bike with a 52-39 chainring and a 13-30
5 speed cogset would be. the rear derailleur
is a long cage crane and it seems to me that a
lot of vintage chains are made for smaller
capacities. what was used on touring set-ups
in the 1970's (and before)? conversely, are there
chains manufactured now that are appropriate
for older bikes? everything seems to trend towards
narrower chains, obviously because of the need
to make cogsets more compact. as always, any
help is appreciated, and i remain
yr obdt svt
