Retro Wizard
I was comparing Campag to the Huret etc that came with the Raleigh 10 speeds I had to set up. First thing to do with them was to take a metal bar and straighten the steel double chainwheels.......if they were too wayward we would claim on the 5-star dealer warranty LOL
I have had a look at a first gen Shimano mech from the mid 70's and at the front it's 12mm, in the middle it's 10 mm and at the back 15mm. The spacer is 10mm wide.
Torqueless is dead right in that a short wheelbase accentuates the chain angle BITD if that was a problem we would expand the front mech cage with a pair of pliers.........slot the pliers in narrow side into the cage itself and twist the cage open. Dirty trick but not a lot else to do No point in putting a larger spacer in as the usual rings were 52/42 so in the small ring the chain was not that near to the spacer...
Endless fiddling while riding is the order of the day
Even that didn't work if you were a big lad as the bottom bracket swayed from side to side knocking the mech into the chainline...........happy days
