Gravel Bike

My "gravel bike" has a new bit of kit... an expandable "trunkbag with fold down panniers".
All told the trunk bag has 1380 cu.in (2.6L) of space for stuff.
My son and I hope soon to begin some bike camping adventures together.
Having just completed a tuned-up of the bike a group ride was the perfect opportunity to make sure the whole package was fully integrated.
