Hope that's a typo, or else you have the longest lasting ultegra 9s shifter in history. Flush the
lever with WD-40, but me thinks, since all else is essentially new(ish), it has to be the lever.
These things don't last forever, some don't last for minutes.

I'm having a little trouble with the shifting of my rear derailleur. 9-speed Ultegra STI shifters
and cassette; Dura Ace triple rear derailleur. The best cable adjustment I can do allows for good
shifting when moving to a smaller cog, but I need to "overshift" slightly (not quite two clicks)
to move to a larger cog. If I move the shifter just enough to click, it won't move the derailleur
enough. It needs a little more push (another click followed by a shifting down a cog also works).

The cable and housing are new, the chain and cassette are in good condition, I've had a shop check
the hanger alignment, the derailleur is fairly new, and I've lubed the area where the cable passes
under the bottom bracket. The shifter has been used for about 15,0000 miles.

What appears to be happening is that I don't get enough cable pull when the shifter is moved just
enough to click once; if I move it a little more and then release, I get more cable pull (or if I
click again and then shift down a cog).

Not a real big deal, but anyone have any ideas for a remedy? Thanks a lot...

Sometimes you can't have a perfect shift both ways. I like to set up my derailleur so that
downshifts are done with just a click and no extra push. This usually makes upshifts slower unless
I'm spinning a high cadence. This is an acceptable tradeoff for me since I'm always spinning fast
when needing to upshift. It's either that or training your thumb to overshift the right amount for
each gear.

Thanks much for the tip Peter, but that doesn't seem to help. The shifter seems OK. There just seems
to be too much friction somewhere...

Are you sure that you had the right type of housing?

Was the housing snugged tightly up to the shifter body?

Does the cable seem to move smoothly if you move it by hand?

You might also check where you ran the cable on its way to the derailleur from the last loop. Try it
on the other side of the fixing bolt.

Before you reattach the cable, sight down the bike from the back wheel. With no cable tension, does
the derailleur line up properly with the smallest cog? If not, adjust the limit screw so it does so.
Then, pull on the cable with your left hand while tapping the downshift lever with your right. Make
sure you are in the lowest gear with respect to the shifter before you attach the cable.

Is there an extra housing ferrule stuck in the derailleur? Somewhere in the cable run? Frayed wires?
Crazed Gerbils?

If that don't do it, you may have worn the sucker out...
