Old School Hero
Hi everyone , For a few years I have been using Campagnolo Olympus MTB chainsets on road bikes . I set them up as a compact double with the granny ring left off .
Using a Campag/Campag copy bottom bracket ISO 102mm length the cranks fit well with an ideal chain line . The Euclid cranks do not seem to work the same so does any one know what length spindle would be best for this application ? thank you kermisking.
 
I think Euclid were supposed to work with 124mm or 132mm Campag bb’s, so 102mm even in a road frame sounds narrow. If you check on the spec for the Olympus, might it be 102mm plus whatever the difference between Olympus>Euclid spec was (assuming Euclid is wider)?
