Ergo Front Derailleur Cable Tension

There was a discussion here a few weeks ago about the need of an
adjuster for the front derailleur. My bicycles have none. With Ergo,
I just pull the cable as tight as possible. The limit being where the
front derailleur will not move fully inward to the stop.

Why do I need an adjuster with Ergo? Is there a device made that
would give more movement per click on the front shifter? With my
50/34 setups, it seems that I need to be on the last click when moving
from the 34 to 50 on many bikes I've setup. I never need to trim the
front derailleur. I'd like to swing the lever less to shift to the
big ring.

I understand that the STI is indexed and needs finer adjustment.

A front adjuster isn't essential but I find one makes setting up easier.
Trimming is needed with my triple derailleur and cable tension has to be
just right to get the clicks where I want them.

Certain old Shimano front derailleurs travel further per click with a
Campag shifter, but they're generally not as good.

You could say Ergos are indexed as well: micro indexed.

You need no adh=uster. Remember to push the thumb button down when you tighten
the front der cable as well. Then the minimum of lever movement will get the
chain onto the next ring.

NOT like the finicky DA or ultegra doubles/triples at all

I recently went to STI for the first time. Getting the rear adjusted was a piece
of cake, everything fell into place. The front was amazingly fussy. It wouldn't
work at all until it was just right. Then, it worked perfectly and continues to
do so. No such thing as "a little bit off" with this.
