We've never ridden one, but a team or two at the Georgia Tandem Rally ride them. I do recall Ric and Marsha of House of Tandems brought one with them 2-3 GTRs ago. I was stunned by the weight. Or lack thereof. It was a possible contender for the "retirement bike". It's sad to another manufacturer call it day.
