...full compatibility with drop posts through all size range.
Funny, I had to buy a PNW dropper because my OneUp was too short :'(
No doubt the longer length of exposed seatpost will be more comfortable, but dropper compatibility with 27.2 posts, which have a maximum drop of 125 mm, isn't a great reason for such a short seattube. I would've liked to see 2-3 more cm to maximize bottle capacity and potential for framebags. Having both a very compact front triangle AND a bunch of bolts for framebags is a very puzzling combo.
In other news, my frame (and others, it sounds like) have been delayed in painting due to a lack of logo decals. Hopefully they restock soon, though I'm not anticipating getting the frame this year.
