I get it. Some vintage frames that are "my size" have seat posts that are a bit short for my preferred saddle height. I rode my PX-10 with the saddle about 1cm short and the stock simplex post extended as far as I dare. I did the same with a Tenax Schwinn. These experiences make me think that BITD, if you needed more leg extension, you got the next size larger frame and not just a longer seat pin. For a while the long campy post was 180mm.
