This looks to be the best forum for this question.
I use my Madison for commuting only to this point. Its only a 5 mile one way commute, so the single speed has worked out nicely. I have however signed up for Cycle Oregon this year, and have been throwing around the idea of a Nexus type hub, to give me enough gearing to make the Madison work.
I talked to the LBS mechanic, he confirmed what I had feared, that the bikes drop outs are too narrow (120) for the nexus 8 speeds. This is kind of what I expected, but had to ask anyway.
So I thought would ask here, before totally dumping the idea. So is there an internal hub that might work? Would it be robust enough to for some climbs including a short 10% climb and an extended, it appears to be 9 mile, guessing 4-6 %. Would it be so ugly, that I would no longer be able to look upon my bike the same? smile.
My other choice is using my Schwinn Tempo (1987, recently overhauled) or as what is always fun, another bike, possibly building up a Cross Check.
My fitness level will be decent. Im 47 and no longer have a real desire to see just how much I can suffer, so the suggestion of "get in better shape and ride the single" will fall on deaf ears.
Thanks in advance for any help. My tech knowledge is pretty out of date, as I did my last serious riding before I was 30, and only started riding again after the chemo 7 months ago. I know little about the IGH, but have been reading up on the subject to some extent. I have no real world knowledge of them.
