@PSM: Had a closer look at your pic and see that you're running 10spd with a master link in the chain. Are your cassette and chain in good condition? That could certainly be the cause of the noise you're experiencing. Some good digital calipers is a nice tool to have as well. 132.60mm is the distance Campy recommends between the links before they recommend replacing. I've let it go longer, but I can definitely notice a degradation in performance around the time it reaches that spec. I see you have a master link in there as well. Not a fan of those, but haven't used anything like that since 8spd. I install a Campy chain with the peened pin, and leave it on. Only reason I would break it is if I was throwing on gearing that required it like a compact crank or something. And then I would still break the chain opposite of the initial peened link and use the special pin (also peened and which you can buy separately) to reattach things if the chain is still good otherwise. Oh yeah, then theres that damn $300 chain tool they like you to use :shock: But I'd be suspect of that master link as well, if all else fails in your troubleshooting the noise.

It is only when useing around 19T. Typical bent hanger I think.

And now for the main question... Did it solve your shifting woes? Have you put a derailleur hanger alignment tool on it to check that it is indeed aligned once replaced?

No hanger alignment but I can actually see the difference.
Looking from above the chain goes right through the jocke wheels and looks paralell to the cassette.

And also important, now I can move the whole hanger, rather than only the dereilleur when fitting my bike in it's case. :)

It was surprisingly easy to unskrew the damaged bolts with this solution. 8)

Probably this was not needed this way . . . .

When changing your Derailleurhanger, make sure you have tools with real good fit.
People need to know that there is a thin line between failure and success. A tool with real tight tolerances can make the difference.
Throw away your mediocre hex and torx tools and buy some good stuff. Like PB Swistools. Pays out on the long term.

Then when replacing a hanger ALWAYS use an alignment tool.
Not an option but necessity. Its not just the hanger that needs to be straight but the combination dropout/hanger.
