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.

I'm not suggesting that, I'm just pointing out that you're making 2" difference into a bigger deal than it is, at least in terms of a gear ratio for general winter riding.

Sheldon's gear inch calculator ignores crank length, you need to be using his gain ratio calculation to include that.

Thanks, did not know that.

Overthinking is very much my style. I'll just try something out with cheap chainrings, and If I don't like it I'll just change it back.

Thanks everyone.
