Cinelli might have been a bit larger, but I presume it was similar.

I assume by the late 60's or early 70's, there would have been somewhat more made. But, it is quite possible the top of the line bikes remained with a very small group of builders.

@jet sanchEz,

Do you know the year of your bicycle? My '68/'69 Colnago had essentially identical braze-ons. Above bottom bracket braze-ons, and rear cable stop. Everything else was clamp-on.



If I was to add a braze-on, it would be adding a clamp-on shifter mount stop.
