105 5700 shifters and ultegra 6700 rear deraileur
Moderator: robbosmans
Ok guys need your help with a problem with the rear derailleur or something else. Right then I have 105 5700 shifters and ultegra 6700 rear derailleur all 10 speed with ultegra 11-25 cassette and kmc 10sl chain . Since I put all this on and ridden for about 200miles it has never been right, it seems to change ok ish but never absolutely spot on . I think the frame is out slightly as I took it to a shop and he said the hanger was bent which he straightened but it was still not brill . I decided to buy a new hanger but when I put it on the mech was not pointing straight down , so I brought an alignment tool and straightened it horizontally and vertically but I am still getting noise as if it needs a 1/4 turn on the adjuster . I have set up the rear without the chain on to make sure that the pulley wheels line up with the cogs when shifting which is all good but as soon as the chain is on it messes up , I have tried 2 different wheels and another cassette but is still out, any ideas

Does the hanger move when you tighten the QR?
Lets go back to basics. What's the mileage on the components? How old is the cassette, how old is the chain?

i don't think the cables are the issue. Something is not properly aligned. You say that it shifts like it needs another 1/4 turn of the adjuster, but you didn't specify which way. Is this in all gears, or in one in particular? Also, have you tried another chain? My initial impression is that you either overcorrected the new hanger, or undercorrected it, which is leading to the problem you are having.

I especially think that cables can be the issue.
If your cables are old, housings are damaged or any other problem will make your derailleur move really unstable.
Make sure that all cable system is nice and smooth.

Change inner and outer cables, remove mech, remove hanger, remove cassette; rebuild.
In my experience an old inner cable and/or a rusty/old/dirt-filled outer cable can have a big impact on shifting, certainly enough to make you think something's broken.
Honestly it still sounds like a bent hanger to me... Pick up a cheap used mech off eBay and give it a go, should give you an idea of what the problem is if nothing else.
