just looked at the gearing chart for the 920 and its not bad, very comparable to a 9 speed 11-32 and actually has slightly less percentage of jumps most of the time compared to the 11-32.
basically the range of gearing is from 21 to 104 which is perfectly fine and works well in a lot of conditions, could be a bit lower, but not bad at all.
still, that $2400 cost is high, throw in taxes here and you are at $2760, thats a lot.
