pillar addendum -
forgot to mention that the first order of business with regard to this component should be to verify the size required.
just because the pillar which came with the machine was 26.0 does not mean that is the correct size.
i have a set of expandable blade reamers in my workshop. like to run one through not to enlarge what is there but just to get rid of any paint, rust, dried old grease and out-of-roundness. then check size. this procedure is even more important in machines which employ seat binder collars. Olmo used collars of stamped sheet which have four ninety degree corners at the rear which dig into the back of the seat tube, deforming it when the collar in cinched down.
possible frame's actual pillar size may be 26.2 or 26.4.
