No, you didn't miss anything. I just didn't explain myself well. My thinking was that instead of having to make do with the 3 gears (20-23-26), I may be able to shift smoother by utilizing 4 gears (19-21-24-27). The next smaller cog in my current cassette is 17, which I can't make good use of now (due to my lack of strength). Am I making sense?
