  1. Is there any reason to not use a Shimano road cassette on an off-road
    drivetrain? Either 8 speed or 9 speed?

    The cassettes I see offered for mountain bikes have cogs I will never use on
    both ends. Seems that getting more choices of useful gears would be better than
    having a 30, 32, 34 I never use never mind the 11 or 12 I don't have enough
    torque or large enough hills for. Something like a 13-28 would be great, but
    isn't sold as a "mountain" cassette.

    So any reason to not use the road parts? I've got an 8 speed setup now, but
    might convert to 9 when I start replacing this stuff.

    Will a 9 speed crankset work well with 8 speed chain and front der? In case I
    get a deal and want to start the conversion there.

    Thanks all.

    No, no problem at all. I use a 12-25 (I think) road cassette on my
    mountain bike, which I use as a foul-weather commuter.

  12. No need to change the chainset as your 8 speed chainset will probably
    be fine with 9s chain. Same applies to derailleurs (though I believe
    you need to match mtb front derailleurs with mtb shifters for indexing
    to work properly).

    Cassettes are interchangeable, the "road" or "mtb" is just a marketing
    term and doesn't reflect any differences in geometry etc.

    The things you will need to change are chain, cassette and indexed
    shifters.

    You can have the best of all worlds by retaining the largest sprocket,
    but replacing the rest of the cassette with a closer ratio "road"
    cassette. I do this on my touring bike to give a 13-24 +32
    arrangement. Then you have close ratios with a bail out gear in case
    you hit a steep hill at the end of a long day with lots of luggage.

    Thanks. I'm in the market for a crankset anyway. Long story, but I presently
    have a clear anodized left arm and a black right.

    I don't feel the need for a bail-out gear lower than say a 28. I've not used my
    granny ring since verifying that it works and I do live in Florida. Anything
    that steep and traction is more an issue than torque.

    Good info. Thank you.
