It looks like the Fandangos come with handbuilt Mammouth rims laced to White Industries Hubs.
They are 26" and I do like the idea of having tires obtainable! As for the thought about the Trailer I do plan to tour with a burley two wheel trailer. It makes things easier and hopefully the toungue weight will be enough to let me ride the tandem solo without too much trouble. Thanks for the help. Karen and Ben's site is amazingly helpful.
The one thing I don't like about the frame is that it is made of aluminum and not re-weldable in the field. Though after lots of research the breaks i have seen have all been at points that are not reparable. And the frame trashed. Hopefully the Fandango frame can live up to the abuse. I'm going to call mtbtandems today and talk to them about their bikes.
