  1. On the new bikes I'm building, we're gonna run a single front ring (34T or maybe 32T) and an XT
    9spd cassette.

    If I run a typical singlespeed ring (possibly w/bashguard), can anyone think of any issues I should
    consider which may pose problems?

    Would a 9spd chain have any problems on a typical singlespeed ring?

    On my trials bike, I use a very small front ring (22T) with trials bashguard, and a 7spd cassette
    with 7/8spd chain. But I'm so sure about a 9spd chain on a singlespeed ring.

    Thanks!

    If it's a proper SS ring, it will be designed for a 1/8" chain.

    Yes.

    But the 22t was non-SS specific, I'm guessing.

    I just read your SS Sprocket question post. I think I can get the info I need from that. Or at least
    it will help.

    Thanks!,

    Many BMX freewheels are 3/32" on which you can run either 3/32" or 1/8" chain. Rings too: plain
    rings suitable for singlespeed usually come in either 3/32" or 1/8", and 9speed chain ought to work
    on the 3/32" variety.

    AFAIK, there is nothing special about a singlespeed ring, other than that it should have tall teeth
    and no shift ramps so the chain doesn't derail. So basically it's like all chainrings were before
    Shimano and other companies started using cut-down teeth and ramps. I just use an old Onza Buzzsaw
    steel ring.

    Running a single ring up front and 9 in the back, you will probably need some kind of chainguard up
    front so the chain doesn't bounce off. A bashguard and a chain-watcher on the inside, for example.

    You should set it up with a chainline biased more towards the top cogs in the back to keep the chain
    from derailing under climbing load, the bash guard will be helping to prevent that on the opposite
    side. Also you can buy bash guards that go on the inside, and make a chain ring sandwich.
