I have also started work on the tandem. I changed the tires to Continental GP3000 tires. I haven't figured out yet what speed the chainrings are meant to work with, but seeing as the timing chain is stamped with Sachs PG and the brake appear to be pre 2000's I am going for 8 speed for now. Still a lot of mysteries left. I have no idea what brand cranks are fitted. The bottom bracket is Omas, which I have never heard of before. And so on.
