My LHT has a 48-36-26 165mm crank with an 11-34 cassette.

My Gunner will have a 22-32-44 170mm crank with an 11-34 cassette.

When I look at the gear inches from Sheldon Brown's gear calculator for both bikes I get confused by the following:

LHT = the 23-34 gear gives me 19.9 gear inches

Gunner = the 44-34 gear gives me 33.6 gear inches


What is this actually telling me - that the Gunner, with the full mountain drive-train, will get me further in the easiest gear over the LHT granny gear? If I understand this correctly then I can make sense out of the rest of the table. I think....

I am not looking for a total understanding, just an idea of how to interpret the numbers I am seeing.
I'm not sure what you're trying to compare, . Where did the 23 come from in the "23-34" referred to in your question? And why are you comparing it to the 44-34. That's the big chainring combined with your largest cog. That's comparing apples to oranges, it would appear.

The smallest gear you have on the LHT is a 26-34. The smallest gear you'll have on the Gunnar is a 22-34. I don't know how that translates in gear inches, but your Gunnar's smallest (easiest) gear is smaller than the smallest gear on your LHT. And both are darn small. The smallest gear on my bike is a 30-26.
