Hello all,
This is my first post to this forum!
I fixed up my old road bike recently: replaced chain, new rear cassette, fine tuned rear and front derailleur setting. I really thought I had done a good job as it was running more smoothly than ever....
Until today, i.e. 2 weeks after the overhaul (i probably did 200 km with it since then - without any issues)
The chain "skips", i.e. it periodically kind of gets off the jockey pulley, which is really annoying!!! When cycling backwards, the chain just gets off the jockey and blocks.
This does not seem to be due to improper chain tension as problem persists regardless of which gear the chain is on.
In order to illustrate this better, I took a bunch of videos. I took 4, it is kind of overkill I know But just so the problem is very clear:

What can I do about this? This is a high quality, albeit old, Campy friction derailleur, so I'd rather fix it than replace it with a cheap one.
Thanks a lot!!!
