Good point, I did not even consider! I just went out and measured my 'reach', and it is bigger on the All City, but also we're comparing my drop bar brifter setup and albatross. Riding the Hillborne this past weekend I felt a bit too far 'back' on the bike, very upright.
I just moved the seat (b17 narrow imperial) up as far as it would go with the Nitto 65 post, which was somewhere in that '1.5cm' vicinity, and yesterday moved the stem a bit lower into the headtube, so I'll see how this feels too.
