While I know and have known for over 50 years what gear inches mean, I never think about that.

I just know from experience what 70 or 100 or 25 gear inches will mean in terms of being a match for...

Yes, on the surface it seems kinda dumb. I agree but then we need to think about what would be better. GI has survived through over a century of chain drive for the simple reason that it works so...

No, it's on the chain's return loop. Everything power related is about the upper loop and the sprockets.

yes, since the the distance between the sprockets is unchanged, and chain used to wrap the outer halves is likewise unchanged, the total length needed is the same.

There's a certain logic here.

Greasing reduces the friction which keeps the stem aligned with the fork. This is easily compensated for by making it tighter, but that in turn increases the stress...
