On one bike I have either the bottom of the range Shimano rear derailleur, or an imitation copy of the bottom of the range Shimano rear derailleur. The spring tension is weaker than many other rear derailleurs. The chain sags more than it should.
With a derailleur like this, the chain rides up on the sprockets more than it does with a derailleur with stronger spring tension. This results in the sprockets wearing out faster. The sprockets don't need to be very worn, before the chain starts jumping teeth.
I will not buy this type of derailleur in the future. I will buy derailleurs with stronger spring tension.
If anyone reading this notices their chain sags too much, this may be the cause. You may also find your sprockets wear out too fast.
There are not-too-expensive derailleurs available with stronger spring tension.
