Hope I understood you, it was quite a challenge. 22:18 = 18:14.75 As you can see, there isn't much difference between 22:18 and 18:15. I rode 22:18 a while ago and it was much much nicer than 18:16. Lots more power, easy to get to riding spots. However, the way a ratio feels also depends on other things like bb rise and chainstay length.
