Thanks guess. I am really just looking for an all around ratio. I was thinking 46/18 but went for a spin on another bike tonight with the gearing at 48/19. Still seems a little tall. A 48/19 is really close to 46/18 in gear inches. i am buying a fixed soon and will mostly be using for fitness. 46/19 I think will keep me pedalling pretty consistently. Which is my objective. So I don't blow out the knees at longer distances in higher gears. Thanks again.
