Setup(s) Bikepacking Spain and France

Bikepacking Setups I have used last year to travel through Spain for 10 days (Focus Atlas) and Germany/ Netherlands/ Belgium/ France for 14 days. (Canyon Grail).

This year I am looking to ride from Portugal back to Germany with about 3,500km in 4 weeks; probably with the Focus Atlas, a Tailfin Setup and Camping Gear. Still looking for tent recommendations, if anyone has a tip.. Durston X Dome 1+ is unfortunately sold out. Also Not sure, if Tailfin Cargo Pack (18l), Frame bag (3,5l), long top Tube (2,2L), and a Handlebar roll is enough Space for a full even ultra light camping setup.

The Focus Atlas is 650B with 2,2 Conti RaceKing, which I think might be overkill, as I am following the EuroVelo Routes most of the time. On the other hand the Canyon Grail might be too much of a racing geometry and tech with the electronic shifting.

As you can see, still optimizing/ figuring out for this years trip.
