Ok, so I nearly bought this the other day, and only the location stopped me. I'm a huge bike fan, my wife less so, but we'd get out more together if we had a tandem, and I wouldn't find it so hard to go slow enough for her to keep up! I'm a vintage bike fan, and an able bike mechanic in most ways, but I don't know everything there is to know about tandems. Can somebody bring me up to speed on what the tandem specific parts are? I believe the front BB is unusual, there clearly a whole range of crank related wierdness that I need to understand, but what else? Standard 40 spoke rear wheel, or are there special hubs? Basically, I'm going to try to hunt down a used tandem for circa $200, and that's going to mean me doing some work on it. The main thing is to be sure that nothing tandem specific is completely knackered, since everything else I can replace or repair easily. Help!
