I want to develop an "eye" for determining useful mileage left on cassettes. Does anyone have a collection of pics showing the teeth of the gear and what mileage they have on them?

I think the differences are too small to see clearly, a pic will only show extreme cases. I got a new chain to go with my new chainrings, and had to replace the cassette as well because the new chain was skipping on the cassette. A new cassette solved the problem but I can only see a very slight difference between the old cassette and the new. Looking at it I would swear the old cassette is still good; not with the new chain it aint!

You're only talking about a couple of percentage points over a distance of about 1/4 inch. That's going to be pretty hard to eyeball.

You can buy a tool to measure cassette wear.

Not to repeat myself, but:

In short: I use the Rohloff tool because I can't trust my eyes, and intimately believe that noone really should.
