I'll be curious for our report. I have a 12-28 on a triple crank. I mostly use the middle ring up front & find my cadence often jumps 10-12 rpm when I shift in back. I'll probably need a new cassette in about 1000 miles and am thinking of getting a tighter group. My only concern is that while I don't often use the granny gear with the big cog, I do on occasion and am glad I have it when I do.
