I am trying to push myself a little as I gain fitness and experience. Have been riding almost entirely on the center chain ring. This past week I started using the big chain ring. Made me feel like such a whimp! One thing for sure, it's faster. I just could not stay in the bigger gears long at all. I did show improvement, however, so I will stay at it.

Question is, what, in terms of gear inches, do most of you run on flat terrain in the course of your commute?
