Do you, or anybody else, have a view on how a "comfortable cruising" ratio on a solo compares with that on a tandem (assuming averagely fit M+F). My solo cruising gear (11) is approx 60 inches, should I order a Rohloff ratio that gives a cruising ratio of say 70 inches? This would fit with your 44x16. How old and how fit are you both?
We weren't prepared to wait for a Tiawanese framed Rohloff tandem so Robin made us a (very) special.
Geared 44 x 16. 11th is about 71.5". I'd say about right. We're both 42 and did over 110 miles on Saturday even though we didn't really feel 'up for it' when we set off. 100 miles in 6 hrs 6 minutes, so averaging over 16mph.
I also have a Raven Tour geared the same.
