Mark,
my understanding is that you had this frame custom built by Calfee. They now offer an Adventure tandem on their website.
I’m assuming that your bike was essentially the prototype for their current stock offering.
Do you know if there are any differences between your frame and the new offering.
Also is there anything you would spec differently in hindsight?
