Looks like Andy isn't answering. I'm in the process of adding a Rohloff to my Q45. So far, the only modification has been with the derailleur hanger. It's too thick and had to be thinned a little bit. I'm not sure, but I think the LBS said all they had to do is scrape the paint of the inside of the fork/chainstay. The other troubling problem is with the shifter. I prefer the shifter to be just below the brake on the right side, but it's too thick. My choices are to have it hanging off the end of the bar or placed next to the handlebar neck. I'm choosing the former as the latter would be to much of a pain to reach every time I want to shift. We'll see how that goes. I'm staying with a chain rather than a belt, so I have a chain tensioner hanging off the derailleur hanger. I don't have the bike back from the LBS yet, but when I do, I'll come back and give a breakdown on it and a review on how it's working.
