Did a test pack for the Brevette, and I think it will all fit!
Sleeping bag and Bivi on nitto handlebar support thingy on the bars.
Electronics in the top tube bag/bento box thing.
Clothes, mat, wet weather gear, 1st aid stuff in the saddle bag.
Spares, tools and spot tracker will go in the add on pouch on the saddle bag.
Frame bag is completely empty for food and all the little things I have forgotten…
Going to tape two spare tubes and some emergency food on my forks.
