My seatpost/saddle "disappeared" (I left it behind when packing up at a trailhead and when I returned it was no where to be found). I never noticed what the post diameter is (I haven't had the bike very long) and now that I need another I need that info. 31.6 would have been my guess, but when I measure, with calipers, the inside diameter is out of round and no dimension is that big. Taken at three points I'm getting 31.54 (straight across, perp to the long axis of the bike), and 31.31 and 31.34 (taken in an "x" pattern diagonally across the long axis of the bike). So now I'm thinking the much less common 31.4. Does anyone have a post they could look at and see if it's marked? Thanks.
