SoI have decided to build my own panniers, primarily because of the cost of buying them for two bikes, but also for the challenge. First step is to build a bending brake for folding sheet metal. Half complete here.
This will be finished in the next couple of days, and then onto fabricating boxes. They will be steel, as I haven't ever welded aluminium, and I don't think a couple of extra kilos will make that much difference. If they did, I can also lose a few myself.
