Saronni by Colnago
(He was laid in honor in the factory of this Colnago frame, and this series. At least this is conjecture, since there are only speculations on the Internet. I think we can safely assume that Mr. Saronni with his friend Ernesto Colnago had built some of these frames and they marketed themselves.)
(I was trying to find more info on this bike and came up with nothing on US vintage forums. I will say the poster on a certain US vintage bike forum called “bianchigirl” should stick to appraising shitty bianchis.)
