Picked up a Surly SteamRoller last year at the end of the season (end of season model). Put quite a few KM's on the freewheel side and finally work up the courage to flip the hub to the fixed side a couple months ago. It is an addiction! Absolutely love riding fixed. Got it in my head to build an All-City Nature Boy for my next build. 35's with fenders, Soma Sparrows, bar end brakes, maybe one of the new light green Brooks...
