BMX shops/stores sell both kinds- each will work with your setup, but your rear hub dictates what kind you need.
It's a standard shimano mountain bike rear hub.
I guess my main question is if I want to use a bmx chain, what chainwheel/rear cog do I need. The cogs that come with the nashbar/jensen kits don't say.
