    New question here. Use of the Rohloff Caliber 2 chain checker?

    I have a Rohloff Caliber 2 chain checker. This tool has two sides, one for use with aluminum sprockets and one for use with steel sprockets:

    > If side A of the Caliber 2 tool sinks in fully, allowing the Rohloff Caliber 2 to lie
    > flat on the chain rollers (Fig. II), the chain wear factor has reached 0.075mm
    > per link. To protect ALUMINUM sprockets from premature wear, chain
    > replacement is recommended at this time. If side S of the Caliber 2 tool
    > sinks in fully, the chain wear factor is 0.1mm per link. The chain should now
    > be replaced to avoid skipping and to prevent wear on STEEL sprockets.

    Like most bikes, mine has steel cassette cogs and aluminim chainrings. When Rohloff talks about sprockets, are they talking about the cassette cogs or the chainrings? Since the bike has both steel and aluminum sprockets, should I just use the side of the tool for alumimum sprockets?

    Thanks!

    Replace according to the "A" side

    First off, I frickin' love that tool.

    Okay, you want to replace when the "A" side lays flat. If you have any aluminum rings or cogs you want to replace your chain before it can damage them, not when it's at the point it can damage the steel. If in doubt, replace the chain, helluva lot cheaper then new rings. My 2 cents at least.

    Most here use the "A" reading....

    ....this one has been discussed some times. (I actually asked the same long time ago)
    I use the "A" too, and when it falls in, maybe have a couple rides more....

    Speedhubnate will hopefully give you nice detailed info on that subject...
    Or look for it on previous threads...he will enlighten you
