Thanks, Denise...I may have to count those teeth on my chainrings and find out exactly what I have. I need to be more knowledgeable about some of this stuff. There was a time, many years ago, that I actually knew a few things about my bike, but I let that knowledge go where most unused knowledge goes ...

SBCTWIN, let me save you some time. There are NUMBERS on each little chain ring if you can find them. Hope that helps.
