Seat tubes with 27.4 ID are gonna fit a 27.2 post after brazing right?
All the 28.6mm seat tubes I'm seeing have a 0.6mm wall thickness
I asked about this on that facebook framebuilders group and someone replied saying that 27.4 id seat tube was for 27.2 od seat post.
Doesn't seem to make sense but there you go!
I'm using the same 27.4 id Zona tube you used on my next frame.
You need .1 of clearance for the seat post to actually slide in, otherwise it’d be a press fit
