Everyone talks about top end and low end when discussing gear ratios. Those are the extremes. i tend to think around what do I usually ride.
If I had a 32 or 29 inner ring that would put me into this ring and cog combo:
29 x 11 = 69.3
32 x 12 = 70.1
34 x 13 = 68.7
That is some serious cross gearing. I suppose you can switch to the big ring. But that again is a cross chain situation. I am running 52 by 36, which is compact enough, otherwise it seems to be a cross chain situation on the flat.

1. No, switching to the big ring would put you right in the middle of the cassette.
2. Why would you not normally be in the big ring on the flats?
