Weird Behaviour Campagnolo Potenza

[Sillyoldman]

Ok, new chain fitted. Had to remove one link from the new chain following the instructions on the video Ajax Bay linked. This means one link was added to the old chain length. The idler run gap from chain to jockey is now 10mm. Leaving the chain uncut (ie 2 links more than old chain) had the chain idler distance to jockey at a couple of mm only. On the stand changing is still lovely. Hope to get out on the road tomorrow. I attach some photos for any comment. 1) small front to large rear, 2) small F to small R 3) trying to show chain gap to top jockey 4) large F to large R.
Many thanks for all your help, please advise if things still cause concern but hopefully this will have fixed it.

That is one sparkly clean bike you have there, @Sillyoldman .
That cage in the fourth image looks spookily close to 45 degrees.

The length of the cable & outer from the stop on the stay to the derailleur seems quite long

I agree with you, but it is a matter or aesthetics. Don't go and open another can of worms now.

Update: 27 miles ridden with no issues. Fingers crossed.

Cheers

I love it when a plan comes together. Thanks for the feedback.

Another 6o miles done no issues bar a puncture

I never knew that was the "Campagnolo method", But my Dad showed me how to do it when I was a kid.
Come to think of it My bike (his old one) had a Campagnolo groupset on it (Record Mk1).
I've been setting the chain length that way ever since.

If your problem is fixed, the great. I've just read this thread and have a totally different possibility.
Mavic Kysrium freehub bodies have a solid nylon(?) bearing which can start drying out/seizing up and make the cassette appear that the freewheel is sticking.

This happened to a friend of mine, freewheel used to screetch and chain would drop as iff cassette was seizing. Was somewhat intermittent.

There is a cross-reference to the problem & solution here

All fixed thanks with many miles done. If anything I am over zealous in servicing the Mavic freehub which gets done about every 600 miles. But thanks anyway.
