I'm a proud new owner of a 1991 Cannondale tandem. Here are a couple of questions:
1. Is there a serial number on Cannondale tandems? I quickly scanned the frame and I didn't see it, for instance on the bottom bracket shell. I can do a more detailed look but was wondering if anyone knew the quick answer.
2. The bike has "Suntour XC" cantilever brakes - probably the originals. It also has a third drum brake. I assume that losing the drum will mean rebuilding the rear wheel given the hub spacing for the drum, which I might do eventually. Are more modern cantilevers a reasonable upgrade? Suggestions?
