Quamen bikes has been making flatland framesets for years and recently have branched off into making street fixed gears. While not as over-built as some of the other models, the Isyar has proven to be a great street frame. Tough enough to take a beating and with the same lines you’d expect from a BMX company; tight rear end, unicrown fork, beefy fork ends and an hourglass headtube.
Big ups to Jim at Orange 20 for the post. Really great video.
