    3/32" or 1/8" drivetrain?

    Are you running a 3/32" or 1/8" drivetrain with you std mtb cassette rear hub converted to single speed?

    If 3/32", whose sprockets turn you crank?
    I was planning to run a 28T Black Market Revolver Lite, but the 28T are sold out until May. There just don't seem to be many other options out there for 3/32" sprockets. Thinking of switching to 1/8" to open the door on a lot more options.

    If 1/8", what cassette cogs turn you crank?
    Surley and Endless Bike have a lot of 3/32" cogs available for ss converted cassettes, but there don't seem to be too many options out ther for 1/8" cogs for converted mtb cassette rear hubs.

    What brand BMX cog are you running? Do all the splined BMX cogs fit the standard Shimano 9sp cassette?

    Thanks

    If using a 8/9 speed with a spacer kit, definately use a 1/8" set-up if you can. Get something like a Mosh 1/8" cog or a Surly. Even though the Surly is a 3/32", the base is about 3 times thinker where it sits on the cassette spline. It will not rip apart the cassette like a standard 3/32" will over time.

    I have a Surly cog coming, but they only seem to make 3/32. Do they work well with a 1/8 chain and front sprocket?

    Where do you get your Mosh 1/8" cogs? I have been looking for a source, but have not found one yet.

    Thanks,

    You can run a 1/8" chain on a 3/32" cog. I found the Mosh somewhere one day but an Odyssey is bascally the same.
