I have what I thought was an ordinary Campy GS BB. I thought I was familar
with this model going back to the early 1960s to whenever they ended production
in mid-80s.
The axle itself, I thought, has always been a solid one peice affair with a
published length of 115mm+/-. However, I have what I was sure is a GS axle that
is hollow just like a NR/Record/C-record/chorus.
The length also makes me think to rule out Triomphe/Victory/Athena/etc.
It is still black colored like I always thought them to be and it also has the
"winged wheel" logo as found on GS components.
All the catalogs that I have read containing GS info do not seem to
indicate that GS BB axles were hollow. Does some one have a later 80s catalog that
describes a hollow GS axle? [sorry for being out of the CR time line with that
question] and if so, is there a date in which this change took place?
In any event, it seems to be totally up with fine milling and workmanship
that we have all known and come to love/covet/etc. Any help would be most
appreciated. cheers-
