    This website gives a handy selection of 5/8 jackshaft sprocket options which will fit onto the SickBikeparts shift kit, to enable a greater selection of ratios.

    I like the fact that you can get an 8 tooth sprocket for the Jackshaft to increase the effective pulling power of the bike. The smallest that SickBikeParts sells is a 9 tooth.

    Those appear to be for a #35 or 40/41 chains not what SBP shift kit sells/use.

    I ordered a 14 tooth. It will work with the heavier 415 chain, but not 410 (BMX) chain.
    To use with 410, you have to grind about 3/32" off the toothed side of the gear so the teeth will be thin enough.
    I retruned it as I did not have access to a bench grinder/wheel.
