Is there any harm in removing or adding spacers to the SA hub to match the dropout width? Supposing of course that the axle is long enough. I don't remember specifics at the moment, but I believe the OLD of my AW hub is 10mm wider than the spacing of the dropouts on my Technium. But, there are 20mm worth of spacers on the hub. I'm planning on just taking 10mm worth of spacers off. If that's not a good idea, I can always cold set the dropouts I guess. That's the nice thing about the Techniums, aluminum frame, but the rear triangle is steel.

rhm: you have a very good point! I've been looking for a 3 speed for a little while and I've only been able to find a 21". I ride a 23" road bike so 21" isn't so far off, but I think the north road handlebars make the bike feel even smaller because the 21" 3 speed I have feels really cramped. So in my case converting a 23" road frame to a 3 speed is the best option if I want to ride comfortably.
