We have a one-piece 26" wheels Cannondale in Covington Louisianna that we left there last year. We're now shopping for another small size tandem. I'm 5'7" and my wife is 5'2" We believe your tandem would ba a good fit us.
26" wheels, great condition, S&S couplers, we have converted to Jeff Jones handlebars, also have all the original drop bars/bar end shifters, custom built for former owner with many upgraded parts. This bike is much more comfortable for me with the 26" wheels. Much more stable on gravel roads. 27 speed, ultegra derailleurs, I can send you pictures if you wish. At 5'2" I can captain this bike, however my husband 5'10" usually captains. Cane Creek shock absorbing stoker seat post is a dream. I am also known as Sepetal.
Sorry all, I started this thread but for some reason haven't been getting notifications of responses :-( I believe I have found a Mocha that will work for us, but happy to see that maybe this thread is helping others find one, too!
