A while ago, my bike developed the symptoms of what I now know to be a 'stiff link'. I suffered for a while before embarking on a multi-week make-my-bike-not-suck project, which has included realigning the derailleurs and putting in new rear brake pads.
Unfortuantely, in all of this I've just made it all slightly less annoying. Or, at the very least, annoying in different ways.
The <a href="http://skunko.damnsw.net/bike-rear.jpg">rear derailleur</a> squeaks when pedaling. It's a fairly shrill metal-on-metal type thing. I'm pretty sure it's the chain rubbing on the metal surrounding the <a href="http://skunko.damnsw.net/bike-close.jpg">upper of the pully-thingies</a> [<a href="http://skunko.damnsw.net/bike-close2.jpg">bike-close2.jpg</a>, <a href="http://skunko.damnsw.net/bike-close3.jpg">bike-close3.jpg</a>]. The red arrows were an attempt to point out what I think is causing the squeaking.
I've fiddled with all the available adjustments, and managed to get it to make less noise, but not none. So, my question is this: what, short of removing metal or randomly bending things into a less-noisy shape, can I do to remedy this?
