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.
The cogs that come in the Nashbar/Jensen kits will work with any chain 3/32" or 1/8" or even wider if you want to. And they will work with your hub too. Sounds like you are golden.
