I'm in the market for a second bike and was looking at the length options for the stem. Is it possible to tell which I should get for the same height as my current ride?
Choices:
stem - 90mm, 100mm, or 110mm

You show quill height then ask about the horizontal reach varieties..
Buying New, the fork/headset will be threadless, I expect , then the steerer tube height and spacers below the stem will be a separate thing ..
