I think my sprocket is getting a bit worn and need to be changed, but I’m looking for a second opinion. It doesn’t have the «shark fins» I’ve been reading about, but the sprocket fins look a bit thin and worn.
Would appreciate someone’s opinion it.
Is the chain anywhere near needing replacing (any stiff links)? Usually you wouldn't change the sprocket until the chain needs to be replaced.
I think I have read in the past that you should always do them both because as the chain stretches the sprocket tends to wear to match the stretch, but I have reused sprockets without any problems.
Anyways it looks fine to me.
