I thought finding out seatpost size would be fairly simple - I did a lot of careful measuring, then decided to invest in some digital callipers, thinking that either they would confirm my thoughts, or at worst give me the definitive answer to the contrary. Alas.
Measurements range from 25.94 to 26.83 depending on the cross section I choose, whether I measure the very top or a bit further in, and whether I open the callipers so they're gently resting, or apply just a tiny bit of extra effort. I decided to measure the seat post I currently have (although I'm doing this as I think it may be a little small because it looks a little overtightened). Those measurements went from 25.93 to 26.81, but mostly settling closely around the 26.6 mark.
What the he** size seatpost should I go for?!
Thanks.
