My 91 was our 1st road tandem and got it in 2019 for 400. Great starter bike for the road. There is something about 27 inch wheels that inspires confidence when riding. We just retired that to part time riding when down south. That is in a closet with our very 1st tandem which is one of those bright yellow cruiser tandems from the Walmart in Myrtle. That is all steel and single speed, not a bike to take seriously but perfect for those beach neighborhoods.
Our 3rd is a 2006, that has ultegra and discs, along with a thudbuster. That is our primary now.
We know what you mean about multiple bikes, probably looking at a trail bike next. Don't want to get started on folders. Between both places we have 14 bikes!!!
