I went ahead and switched it to 170’s. Lots of great info everyone shared, as always. I‘m a spinner, I stick to a cadence for the entire ride. Habit I picked up racing triathlon and using cadence sensors. I was most worried about knee pain which was brought up a lot. As of now I don’t have any knee pain and I want to keep it that way as I get older. Thanks again to a great bunch of people.
