They're based on Mafacs centrepulls, which were made in the millions and therefore easy to find should you need to?
Not that bike shops are super common in Morocco where he rode but even if they were, my (admittedly very vague) memory is that the majority of bikes were not that retro and usually carried mostly cheaper bikes from the far east where the bike shops could get decent supplies of spares rather than what looks like quite overpriced spares for Mafac. Also, other than bolts, pads or cables, not sure what spares he'd need. I'm okay with people choosing whatever they want, I don't have to agree though.
