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.
They're definitely worn, you can see the valleys are getting elongated and the peaks are getting thinner. I always found it helpful to find a picture of a brand new sprocket to compare with.
