Before even starting the tour we have received a number of inquiries on our gear and bike.  We will update this as we make changes during the tour.

Our tandem is a Calfee Tetra that will have about 4000 miles of riding before we start our 2021 tour.  We love this bike!  It handles like a carbon road bike!  (Well, we exaggerate just a bit.) 😊   But like always the real important stuff is in the details that follow.  Special thanks to Kevin at Tandem Cycle Works of Denver for a perfect build and fit.

A bit more context on our component selection.   We spec'd a lot of carbon to reduce the effects of road vibrations.   Then we went with a belt drive, internal hub drive train for minimal maintenance on the road.  The internal hub also removes the need to pull the cassette to fix a drive side broken spoke.

    1. Nope we are using tubes. I know how to repair tubes on the open road. Not as good with tubeless.
