My gut tells me that all early 70's Colnago Supers are made for a standard 27.2 seatpost...But somewhere deep in my brain I seem to be recalling that some early bikes took a 27.0... Did I read that somewhere years ago? Simply dream it up? Lose some data in the fog that was Northern California in my early 20's? Can any early Colnago owners out there confirm?
