There is a way to calculate which would be best for you. Post the gear which you spend the most time in, and which direction you shift the most. (up or down) & what chain ring you are in in the front. (Middle ?) And I will give you the right choice. There is NO reason to wait till you wear out the old one, before you switch. You wouldn't wait till you wore out your shoes if they didn't fit right. Life to short, if you can afford it, go for it. Your talking under 50.00 dollars any way. Buy it from the LBS, & they will put it on for like 10 bucks..
