ha I was toying with the price, I was kinda intrigued the first time I saw them but after the "go to hell" look my gf gave me when she saw them and thinking about biking around with card suits on my crank I think it's safe to say they won't be on my build. I have too much time on my hands today apparently.
Though I did price match the all city black cog for $15 though, so I'm gonna pick up a 17t rear cog for the back even if I don't replace the chain ring.
