This is a 9-speed setup. The wheels, crankset, derailleurs, and brifters were all working perfectly on the previous bike they lived on. I will look to see if the left brifter has a micro-shift mode. I'd love to find it, if it exists.
Basically, the problem is that there are three positions for the left brifter, and they are all too close together. The low setting doesn't go low enough, and the high one doesn't go high enough. Setting the limit screws, as described by the video that u2chin cited, doesn't seem to help. Cable travel is inadequate, and that seems to be the brifter's fault, not the adjustments on the derailleur.
And this is true not just on this bike. I see it on a lot of bikes, and I figure I need to know some trick, but I haven't found it yet.
