My local bike shop here saves short lengths of chain when they shorten it, for other customers, which are new, (old long chain stay MTB,
I need more ., i get it , same model of chain, that's my source..

other that that, buy 2 chains, and extra quick links, to add additional links . buy in the future just one,
since you can continue to take links from that other sacrificial chain..

+, Places that service recumbents buy chain in bulk on a long reel .. say how many feet you need.
