cassette wear tool - worthwhile?
there are plenty of posts in the archives regarding chain-wear tools and their repeatable but overly-conservative approach to chain replacement (vs a plain-old ruler).
does anyone have a perspective on cassette wear tools, such as the rohloff one?
instructions can be found here.

and these:
Seriously,
the reason for a chain wear tool is to beable to replace a chain before it damages the cassette, (which is before you'll see or hear problems). When the cassette's worn out, you'll know it.

hahah 
fair enough!
i guess a worn chain is likely to take out a cassette...but a worn cassette is less likely to take out a chain, no? if a new chain skips -> replace the cassette.
thanks!
(the ruler works just fine for me for measuring chain stretch/wear.)

If you think you need a tool, it's probably time for a new cassette. If the teeth aren't symmetrical, it's done.

You can check cog wear with your fingernail, just drag it across the flat side of the tooth, out towards the edge. If your fingernail catches on a little lip just at the edge of the tooth, then your cassette is finished or close to it. The more pronounced the lip, the worse the wear.
