    Rolf cassette wear checker

    I have one. I do not have the instructions and can't find the unit on the web to copy off instructions. I would like to know how to use it properly.

    It seems to me that I can make any cassette new or old be 'sticky' and hold the chain. I was working under the impression that the tool was to check if a cassette was worn and 'held' the chain to much, not allowing it to release to the next gear smoothly.

    I need to know how much pressure to hold the gauge/tool to the cassette with.

    I think the reason you're not finding anything on line is that you have the name wrong. Try googling Rohloff cog wear indicator and see what comes up. FWIW, I have one of these, and I have not found it to be terribly reliable.

    The only totally reliable check is to install a new chain and see if the chain skips on any of the cogs under heavy pedaling pressure. I'd never toss a cassette based on the reading from any tool. I only one cogs skips, you may find that the worn cog is useable with another chain, having only a few hundred miles of use - still good enough for a commuter or bad weather bike.

    Thanks. That solved that. Now all I need to do is practice on old cassettes vs new ones to get a good feel for the difference

    Well,
    All of this stemmed from trying to adjust the changer in the rear and I kept getting an issue with skipping in the middle gears. I would fix the middle and then have problems else where.

    I will now start a tread on chains.

    check your rear dérailleur's hanger , it may be bent, or your cable /housing need replacing due to age.

    Worn cogs are not the reason for poor shifting. If the chain skips over the top of the teeth under a heavy load, the caogs are worn out, but shifting to them should still be fine. The only times I had chain skip, I didn't have any shifting problem, but the first hill revealed worn out 19-21T cogs, when I stood to pedal.
