I measured the ID with a pair of calipers and came up with 27.2. I then re-lubed the post and tube, but the post would not insert more than a couple of inches. I also tried a American Classic 27.2 without any luck. Any chance that C&V Bottecchia owner could provide some insight? Does anyone know if this vintage Bottecchia seat tube is actually 27.0?
What size frame and what tubing? My 1972 23" (58.5cm) SL frame is 27.2 but 25" frames are SP and usually 27.0. By the mid 80's there were many more tubing options and smaller increments between frame sizes so it would be hard to generalize.
