Huh. I just looked at the dimensions on the frames and the difference in top tube length is only 5cm between the 18 and 19's. I'm pretty surprised about that.
I'm not, got several 20s and a couple of 18s top tube length is similar 20s just ride taller.
They definitely used a different approach with their road bike sizing - my Edge is quite square.
I managed to install the headset crank and seatpost/seat last night. I stuck the wheels on and the bars with the spacers I had available from my Hillside and swung my leg over the bike. Felt surprisingly good. The old roadie rule of thumb about the bar covering the front hub certainly doesn't apply. Going to get some more spacers today so I can get the bars on securly. I'll experiment with handlebar height to determine if I'm going to cut the steerer.
Cheap, light and strong. Pick two.
