I see that this bike's been made at least since 2007, however there is but 1 posting mentioning it in this forum. We are looking for our first tandem, and there doesn't seem to be much choice out there. The Schwinn Sierra is the only aluminum frame bike, that has a suspension and disk brakes, and until the stimulus money really kicks in, the streets around here (Chicago) demand both. I suppose the penalty is weight, but no manufacturer quotes weight anyhow. Very few LBS have tandems, and the closest ones have only Schwinns.
So, has anyone had any experience with this bike? Also, the top tubes are configured oddly, does this affect stiffness (or other frame attributes)?
