This is a great single-speed, especially at BT price. The frame is the same scandium that Kona used for their top of the line Major Jake. It feels responsive and light, no real complaints so far. Because it is a cyclocross bike the handlebars are a bit wider (for stability). If you want to race single speed you may want to swap out the wheels (sturdy but bricks), and the seat isn't the best (but what stock seat is?). The 'fixed' cog is not included, unlike some other Kona SSs.
Kona's single speeds are put together much better than others I have riden, particularly commuters, I definitely recommend.
