Can anyone recommend someone in New York City who can put couplers on a frame?

Bilinky They are pretty darn close; nobody's going to let you watch anyway.

Thanks! I may not be able to afford to put on enough couplers to get the tandem in 2 suitcases, but I'll see what they can do.

I could see that project getting more expensive than a call to BF asking them if they will sell you a frame (or complete bike). They say they don't sell frames but they sometimes get overstock just like anyone else. At least with the singles, don't know about the chance in a tandem.
