I really would like to put an IGH on my new build... either the Alfine-11 or a Rohloff. The only reason for hesitation on my part is the whole drop bar shifter issue. The aftermarket solutions seem a bit clunky to me. Right now I'm leaning toward an added little bar extension for the shifter; I've got one that I used at one point to give me some additional gadget mounting space on the bars of my old hybrid.
