Re: 1969 Cinelli SC
The tubing is Columbus but interestingly not all Cinellis were. a handful were made with 531.
The donor bike, either ironically or fittingly, was a 1970 Windsor also known as "The Mexican Cinelli." it was perfect for the job because it had low miles and had not had anything changed over the years.
I dont have a pic of the poor thing other than this which I took beecause the previous owner never removed the bar tape before putting on new tape. There were like four layers.
