Since there are some companies making 86BCD chainrings, Thorn being one of them, all of those Stronglights and SRs come back into play. Some of the other Japanese cranks in the 80s also came in 130/86 BCD patterns. Those will go down to a 28T small ring. Plenty of them on the bay. A lot of the Sugino and SR 110 doubles also came with 74 holes drilled as well.
