Bikepacking supports to strap dry bags to? Can't say I fancy the look of them for any significant load - they're not triangulated either vertically or horizontally, and the latter means there's the potential to end up in the spokes in case of a bump.
If only there were some proven way of securing bags either side of the back wheel, maybe it could even provide a platform above the back wheel so one wouldn’t need a swinging load on the seat post.
What is this. How does it work? The racks(?) on the seat stays.
