I’m aware cross chaining is bad and don’t do it while riding but when replacing tube on back wheel once finished my chain is rubbing against each other whilst cross chained.
Please excuse my ignorance as I’m very much not mechanically minded. Can’t help but thinking even when cross chained the chain shouldn’t be touching like this. Do I need to do something to rear derailleur or have I done/doing something completely idiotic? Thanks

Your chain is far too long.
With chain in largest front chaining and smallest rear sprocket the chain should be so long as the pulleys in the jockey cage are vertically aligned.
How to use a link extractor : [https://www.youtube.com/watch?v=29bMrNgKUaA](https://www.youtube.com/watch?v=29bMrNgKUaA) . nb its best to find if you have a quick link and remove with quick link removal tool. Or use this guide [https://www.youtube.com/watch?v=6s1LR63ixqE](https://www.youtube.com/watch?v=6s1LR63ixqE) < how to remove quck link without tool.
If you use the link extractor its easier to replace with a quick link that get the pin back into the chain.
Cross chaining is using the largest front chain-ring with the largest rear sprockets or vica-versa, it causes dramatic premature wear of the chain-rings and rear sprockets. You want the chain to run as straight as possible from the front chain-rings to the sprockets at all times.
Chain too long
😱 long chain alert!
What’s it like in Big-Big ? It needs to be just long enough to shift into big-big.
