Ozone co2 was a later incarnation of the Bigfoot Smokestone. Seen a few subtle differences between them. IIRC the cable routing on the top tube runs literally along the top for Ozone. Mine runs along the side.
Some other incarnations include plate type drop outs, and scallops to the chain stay to allow a bottle cage on the down tube.
I did say the differences were subtle!
