Understood, but one could stay with 11 speed (personally, I'm not a fan of 12)...and a 34T is a pretty big cog. How low are touring bikes typically geared?
You want sub-1:1, ideally 20 gear inches (or a bit lower) if you're fully bagged. Which is why triples were/are great things--they give massive range that is actually useful, although with lots of overlap--and doubles just cannot match it....the closest with a road BB and a double you can get is a 48/32 or 46/30 double and either a big Shimano cassette (the 11/34 would probably get you down to 24 gear inches?) or a Road-Link.
