There is a backlash in the rear derailleur
Hello! I have equipment compagnolo record titanium! There is a backlash in the rear derailleur. On the picture.
Can you do something or just buy a new one? Sorry for my English, I'm from Russia. Thanks!

There has to be some clearance in the upper mount pivot to have the der be able to swing with the shifting forces and chain wrap duties. The question is whether the upper pivot is so sloppy that it effects the shifting/indexing. Does it do this? Andy

The leave as is. Don't fix a working part. Andy

I'm not clear on what the problem is but you may be interested in using this site by Sheldon Brown. He is (unfortunately he passed away a few years ago but his website still exists) a popular expert here in North America and has some articles in Russian. I hope this helps. https://www.sheldonbrown.com/russian.html

02Giant- So many people share this pain these days. Too many. Whether it transfers to the vote will be the big question. After 11 presidential elections I've lived through I have hope but no expectation of the general public seeing beyond their elbow and now what their hand is holding. Andy (the guy with too many analogies)

Here are some parts- if it's a broken spring, then part may be available.

Rear derailleurs with many thousands of miles of use can develop excessive side play at the main pivot. The C-clip that holds the parts together can be removed and a shim washer placed behind the clip to reduce the side play. I had one with a .25mm shim in it to fix the problem.
