I have a NOS Jack Taylor tandem F/F that I really need to sell. It's a 21X1 8 Double Diamond with rear carrier. Just too small for us. I've got 1K in i t and that's what I would take for it, plus shipping. See here: http://www. flickr.com/photos/meauxtown/sets/72157615666099805/ Measured from center of bb to the top of the seat tube. If you hook a tape on the seat tube and measure to the center of bottom bracket you've got it.
