I have many years (since early 70's) riding experience but because I'm getting older (61) and arthritis it makes sense to go to a recumbent that I'll be using for touring. There's some requirements which is that 1) a adjustable seat back, 2) tadpole design, and 3) the same size tires all around. I want to stay with 700 wheels and have read someplace (don't ask where, I can't remember) that 700 wheels have some advantages over smaller wheels. The only real disadvantage is a slightly bigger turning radius. Also, it makes no sense to carry different size tubes and maybe spare tires, when touring. The Catrike 700 looks like a likely candidate except the seat back doesn't adjust.
So, with those 3 things in mind, adjustable seat back, tadpole and able to use 700 wheel set at all 3 corners, any suggestions?
