For instance, if I understand correctly, both the Ross and Venture I have measure the same, but the Ross feels much bigger, and more like it's the right size. I don't know the best way to go about trying to get one fitted.
I looked at geometry charts and tried to figure what I liked about a current bike and compare to the numbers of one I am considering. It doesn't matter what size they call it, what matters is the actual dimensions of the thing.
I have or have had frames of 62, 63, 64, and 65. The "65" fits better than the 63 because the top tube is shorter.
I know from riding I like the steer tube to be uncut, or 300mm, with the stem at the top with no spacers under it.
Seat tube angles figure into it, but you can slide the seat back and forth and I use a zero-offset post to get a little further forward.
