Campy Upper Spring

[dabelknap571]

sorry if this is a repeat.... Looking for help replacing the upper pivot spring on a Chorus 11 Speed rear derailleur(non c-clip type). I'm fighting some chain slap and have gone through all the chain length setups and have everything shifting wonderfully, but with the roads in upstate NY I hear it all too often. I did increase the tension slightly by inserting a small shim between the upper stop and the hanger which did improve the situation and proved (in my logic...) that the spring is the culprit. Thanks!

A question out of pure ignorance--do the Campy 11 rears not have the extra hole that lets you increase the spring tension that is there on the 10s?

Yes, they do, part number RD-SR-016 BUT starting in 2012, that back plate/bolt assembly can't be taken apart and put back together w/o a special tool..that Campagnolo NA has.
So, if that plate is held on with a clip..yes, you can take it apart, move the spring end over one hole, and put back together.

And just to tease us they left the higher tension hole visible behind the non removable bolt…..
