Knowledge threshold reached and exceeded - 6700 RD
Soooooooo, I spent a good deal of the weekend trying to fine tune my front and rear derailleurs. The rear one in particular was problematic. No matter what I do I cannot resolve the following: either I can't shift into the smallest cog with the other gears all perfect OR the third largest cog is off (lots of rattle / skipping) with all the others working fine. In the former case, looking over the rear derailleur shows that the pulley guide is a few mm too close to the spokes.
Things I have tried or looked at:
- barrel adjustment
- re-installed rear cassette (slight improvement; maybe the rear lockring wasn't tight enough)
- checked spacers on the rear cassette (6700 cassette, pretty sure the spacers are all the same width). The gaps between cogs appear uniform to the naked eye.
- Limit screws don't hinder movement
Things I haven't tried yet:
- cleaning the cables
- Checking the rear hangar is straight (not had any falls on it though)
Which of these do you think is more likely? Or have I missed something obvious?
Thanks in advance for taking the time to advise me

I've found that for 6700 the cables have to be lubed, the rear mech outer has to be longer than you expect (i.e. with a straight run of outer into the mech).
Since I've done this, my Ultegra shifts very well. If this doesn't work then get the hanger checked.0 -
Thanks - seems to have done the trick0
