I’m well aware of the advantages of lightweight bikepacking. But sometimes you might want to take more. Like, for example, crossing an arid region where you’d want plenty of water. I’d imagined a sort of saddlebag affair where the side bits were triangular to match the rack sides. You could strap it all down tightly and the weight would be as close to the rear axle as possible and hardly affect handling. That might be tricky for a bladder, having said that, but bottles could be good perhaps.
I also have a feeling the traditional rack could be redesigned for bikepacking purposes. Anyone have the means to bend alu tubes? Or lay up carbon fibre?
Btw the rucksack/rack idea had also occurred to me, and I’d consider it for anything that was to include technical bits. But then again, I might as well just use a rucksack – for some reason I don’t mind this much at all, having done enough Polaris challenges this way. If my kit’s light enough I don’t notice. Helps with bike carrying too.
