regarding fittings -

Zeus bottom bracket spindles for cotterless chainsets were offered in both 55mm centres and 57mm centres
the 57's would be for use on 70mm shells and the 55's for use on 68mm shells

for a two plateau drive train there are four model permutations:

114 X 55, 114 X 57, 118 X 55 & 118 X 57

suggest for your application the 118 X 55 would be the one you require

Olimpic components -

in case you search on this manufacturer remember to spell the name with an i rather than a y

pedals, hubs and caliper brakes were produced

there was a top model hub which very much rivaled the Campag R/NR model




a variety of their products can be seen at VB -
