I don't usually post trick videos here, mostly because I assume that most of the people who come by here probably visit more than one fixed gear related blog regularly, and most other fixed gear blogs post videos all the time.
That said, I think this one makes the cut, its just a quick clip of popular Seattle based fixed gear rider Keo Curry being steezy as fuck.
And if for some reason that got you thinking of the olden days of smooth tricks on track bikes rather than the current FGFS phase of jumping leader bikes with 26" wheels off of ledges, I suggest you watch the following:
