You're probably right. Also the stock cog is a 20, not 22. So with the two rings, I get from 20" to 106". Disclaimers: I used mostly "parts on hand", so the crankset was from a projected AHH build that never happened. Or, to put it another way, I didn't really plan the gear range, but I knew I wanted to be able to go real low for the hills around Berkeley. I usually cruise in the 4/5 on the big ring. Dropping from there down to the 28" ring when hitting something steep has been pretty sweet.
So, yes, the 20x8 + 44 is probably more rational :.) But every once in awhile it's fun to rev up to the 106 and pace roadies, until my fat self runs out of steam :.)
