I went up to my family's summer house this weekend to get the rest of the bike, and some tools home. Now I know how I'll be spending my spare winter evenings
The saddle isn't going to be quite that high - I just popped it on to get a view of how the build will come together. But still, at 5'10'' I should be on a larger frame than a 16" C-T. So it's going to need some seatpost and stem to fit me properly.
With the seatpost at the minimum insert mark, and the 155mm. stem, it's about the same as my 17" C-C Wheeler: 70cm. from BB to saddle, and 70cm. horizontally from seatpost to bars.
