Mark-
Nice going on the pics of the orange track tandem. At the risk of sounding corny- I would be honored to ride a Cinelli track tandem on the boards. I LOVE Cinellis and I LOVE track racing. You gotta believe that whomever built this frame knew that some racing dudes with big legs were going to ride the heck out of it, so, no shortcuts were taken. Top-quality and care all the way, right?
I don't yet have a Cinelli tandem in my collection, but here's some of the Cinellis that I do have:
