    Gary Fisher Rig

    What kind of cogs does the GF Rig take, and what all is involved in changing one?

    Nah, it's not a freewheel. It's just some flat metal cog.

    Post a picture. Sounds like a cassette cog. Does it have threads or a spline pattern?

    Yeah, GF Rig Mountain Bike. I've got a fixed gear road bike and it has a fixed cog on one side and it has a freewheel on the other, and I just know that whatever is on the Rig isn't either of those.

    and you're not in luck. Of all the cogs. I have a 19t and 17t Chris King Cog.

    Let me know if you need either one

    Ah, I've got a 19 now and I think a 17 would be too hard. Thanks for looking though.

    You should be able to pick up a cassette cog at the local bike shop for $5-8. It may be called a BMX cog.
