In your opinion would you recommend them over Derailleur
Draws deep breathe.
If you only have one bike and you like going quickly then no.
On the other hand, they're perfect for riding on unsurfaced trails and tracks and, if I had a commute, I'd plump for a hub gear for that.
Provided I had a "weekend" bike.
It has to be said that most people that I know with Rohloffs love them. I respect rather than love mine.
I use my derailleur bike for fast or long rides.
I would strongly advise riding one. If you can't, stick with derailleurs unless you have issues with derailleurs.
Without wanting to muddy the water further, have you considered the Alfine 11 ?
It's much cheaper and you can get STI type shifters.
Downsides are the narrower gear range and they're possibly not as reliable.
A friend has one on his commuting bike and he loves it. It rides as well as the Rohloff from my limited experience with it.
