And no, I don't mean the personality that appears on this board. While I enjoy reading his posts, I was wondering what "53-11" stands for. I know it has something to do with the gearing of a bicycle. Is it a 53-tooth large front cog and a 11-tooth small back cog? Or a 53-tooth big front cog and a 11-tooth small front cog? Also, how do I determine what I have on my bike (other than going to the manufacturer's website and looking it up on a stock bike)? Thanks in advance for the information.
