I almost was remiss in mentioning that this build was facilitated with the assistance of several forum members. I've had help from multiple people with bits and pieces for the several builds that I have in the works, and I don't want to mess up the crediting, but I certainly am grateful for all the kind souls here.
Also - measured the seat post. It varies from 27.2 to 27.06 as I take a few measurements. Anybody have a legitimate 27.2 they want to trade for a post that could be 27.0 with a couple minutes of work with some 600 grit wet-dry?
It's Campagnolo.
