I am currently coming up with the specs I want on a custom expedition touring bike. I am strongly considering a Rohloff. However, I also have a high cadence (105-110) so I really like small steps in gearing.

Is there any reason I can not use a front derailleur with a Rohloff?

I understand this somewhat defeats the purpose of the "no derailleur needed" benefit but the 13% jumps are not fun to me. Of course I would need to use a chain tensioner and the chainstay would be quite long at about 49 cm (over 19") so I would have some room to play with the chain line. The rear dropout would be a Rohloff OEM fitted with a standard rear derailleur hanger.

I would probably use a 32/34 on the front with a 16 tooth on the back. Yes, I know these are really low grears but that is what I use/need/want. Should I spin out on the top gear and I would be going about 26mph which is plenty fast for me on a fully loaded bike. I also understand this would be a "not allowed" low low gear.

Thanks in advance!
