This is a follow-up to the question I need to replace a cassette for CS-HG500-10 but want to go XT
Yesterday I replaced the cassette, as well as the chain and the jockey wheels and went for a ride. The problem has not disappeared.
I'm thinking that the chainring is completely worn out, but I'm also starting to think about the tension of the chain.
I'm using the biggest chainring almost all of the time, and was in the bad habit of using it with the biggest sprocket of the cassette, cross-chaining the entire range. I've used this chainring about 7500 km (maybe 3/4 of that distance).
When I use the middle chainring (it has 3 chainrings at the pedal), the problem is pretty much gone.
Here is a YouTube video which I made today, where I'm fully breaking and then putting pressure on the pedal, you can see the chain jump.
Here are some photos of the chainring:
I have already ordered a replacement, but I wonder if chain tension could also be a factor with this.
Could this problem be removed by increasing the chain tension, or does it look like I generally should increase it after replacing the chainring? How could I do that?
Update: The new chainring arrived today. I took pictures of both and compared them. Here is the result:
