There’s some rubbish written about the drag on Rohloffs.
We’re just back from a month in France during which we did 2000 miles of which 700 was off road. (previous to that it’d only done 1000 miles)
The Rohloff was ace.
Having said that, if I was on a budget then 3 x 9 works well. Make sure you carry a spare mech and hanger in case you drop the bike though. ;)
