My wife and I are proud new owners of a Burley Rock and Roll tandem we got for a great price this past weekend. We are new making all the adjustments, and I have one question. It has an adjustable stoker stem, and even setting it at the shortest position, the seat to handlebar distance is significantly shorter than that on her road or mountain bike. I can solve this issue by installing a fixed length stem 110 or 120 mm, but then I started thinking...should I be using her other bikes (which fit well) as the correct distance or are tandem stokers naturally using a shorter distance? Any advice before I go out and buy a short fixed length stem? A similar question is regarding the handler height, should I use her current bikes as a gage, or should I set those higher, which may be more comfortable?
