^ Thanks for the visuals, RHM. I'll order a 20t, 21t AND 22t cog. All in chrome.

I spoke with a pretty knowledgeable guy at UBS about several SA products and learned some interesting stuff. Did you know the S3X threading is the same as a SS freewheel, so you could replace the fixed cog with a SS freewheel and have a 3 speed where third gear is direct drive? Pretty cool. Also, they're developing a freewheel version of the S2C kickback hub. Although, I'm not sure why someone would want that.
