You're also going to do have some pretty big movement of the rear wheel to get onto that 32. Might even be too much depending on your dropout. I nominate still using crappy friction parts.
Well, I might or might not find a 5-speed freewheel with a 21 and a 30 tooth cog. And if I have to take the freewheel apart to customize it anyway, why would I want to carry around three cogs that I won't be using? I don't care about the weight, but it seems pointless.
As I said, I've never done this before. Are you saying that the 36-32 combination and the 47-21 will position the wheel differently in the dropout even though the total tooth count is the same? I didn't think that would be a problem.
