Yes, but 46/19 is about 64GI, which is really not a lot...

How much do you "feel" the difference in speed anyway?

64" with 165mm cranks is less than 0.1% difference in gain ratio compared with 66" and 170mm.

Thanks, but why would I change the crank length? I know that different crank lengths influence the gain ratio, but as I don't want to change the crank, I don't see where that's relevant?

I'm using Sheldons calculator which should factor in the crank length.
I'm at 72" at the moment, and would get to 69" or 66" with 44t or 42t chainrings respectively, or 64" with a 19t cog.
All with 165mm cranks.
