Shifting problems w/new compact crankset

[Triskeliongirl]

A few more thoughts:

OK, here are the problems - both with the front shifting:
A) I'm dropping the chain A LOT (more than half the time) when shifting from big ring to small. I understand this is a pretty common problem when converting to compact. ...

B) The shift from small to big now takes a very hard push of the shifter. And frequently it "groans" during this shift.

I have been using compact cranks (50/34 elliptical) for a few years, and disagree that this is a common problem with compacts. As I said above, it happens only when the lower limit screw is set too far. Likewise, in point B you mention having trouble shifting back, this suggests the uppper limit screw is set too far. Before I did anything else I would adjust my limit screws. If that isn't enough, I would look into a compact derailleur.
