So, aside from the whole FG vs SS and coasting vs. pedaling debate, I'd really like to know more about the mechanism of a FG/SS instead. Like noglider said, the lower the crank-to-cog ratio, the easier for hills, but max speed is limited, and vice versa. But isn't it possible to create the same ratio from more than one crank-to-cog combination, and if so, what are the differences, say in bigger cogs and cranks?
Thanks for the help guys!
