Won't Shift to the 11

I just put DA 10 speed stuff on my Trek 5200. I have a 11-23 cassette and can't get it to shift to the 11. The "L" screw is all the way out and I have as much tension off the cable as I can get and still be able to shift up. When its on the 12 and trying to get to the 11, I can push lightly on RD and get it to go to the 11, it just won't do it on its own. Any ideas?

How old is that little loop of cable housing that goes into the rear derailleur? That's generally the first piece of cable housing to act up.

To be sure, try this:
remove chain
undo cable
stand behind the bike and unscrew the limit as much as it can go. Kinda eyeball the pulley with the 11t gear. Is it in the same line?

| <---- 11tooth grear

| <---- top pulley

If it looks like this:

| <-- 11 tooth

_| <--- pulley (the underscore is just a way for that line to move over, I can't seem to get it to work with just spaces)

Then you are good, this means you can put some turns on the limit screw.

If not, check rear dropout and/or derailleur hanger.

The "L" screw is the low gear limit stop.

The 11 is the highest gear, so the "H" screw is the one to look at.

Other possibilities include a bent hanger and excess cable friction.

Good catch by the master.

Yeah, get on the right limit screw and things will likely improve.

That doesn't definitely rule out a cable/housing problem. Could be a poorly finished cut end on the housing, could also be the housing is too short.

Thanks for the advice. I will look into all of that. Is there a poor man's way of checking if the hanger is bent short of buying the Derailleur Hanger Alignment Gauge or having my LBS do it?

Check to make sure you have the cable clamped right on the rear der. There was a thread just the other day with somebody with the exact same problem and he had the cable clamped wrong which wouldn't let the der. drop down onto the smallest cog.

Found it. It was on a different forum. The cable wasn't clamped wrong; The tab that clamps the cable was turned wrong and wouldn't let the der. drop down to the small cog. Here is the link:

That was it, the rear derail cable clamp washer needed to be turned 90 degrees. THANKS. I never would have come up with that one.
